Talk: Saga: Continuous Construction and Serving of Large Scale Knowledge Graphs

Abstract: In this talk I present Saga, an end-to-end platform for incremental and continuous construction of large scale knowledge graphs we built at Apple. Saga demonstrates the complexity of building such platform in industrial settings with strong consistency, latency, and coverage requirements. In the talk, I will discuss challenges around the following: building source adapters for ingesting heterogenous data sources; building entity linking and fusion pipelines for constructing coherent knowledge graphs that adhere to a common controlled vocabulary; updating the knowledge graphs with real-time streams; and finally, exposing the constructed knowledge via a variety of services. Graph services include: low-latency query answering; graph analytics; ML-biased entity disambiguation and semantic annotation; and other graph-embedding services to power multiple downstream applications. Saga is used in production at large scale to power a variety of user-facing knowledge features.

Talk: Artificial Intelligence And Digital Pathology: Making The Most of Limited Annotated Data

Abstract: Obtaining large datasets with detailed annotations for medical imaging AI projects is a time consuming and expensive process as it usually requires the input of expert radiologists and pathologists. Collecting data to train outcome prediction models is even more challenging as the number of patients with both imaging and follow up data may be small, and only weak labels are available.

This talk will describe several semi-supervised and self-supervised approaches which can make more efficient use of small and/or weakly labelled datasets. The focus will be on digital pathology but the methods described are applicable any medical imaging modality.

What You’ll Learn: Self-supervision and smart sampling strategies are essential in digital pathology

Talk: Outracing Champion Gran Turismo Drivers With Deep Reinforcement Learning

Abstract: Many potential applications of artificial intelligence involve making real-time decisions in physical systems while interacting with humans. Automobile racing represents an extreme example of these conditions; drivers must execute complex tactical manoeuvres to pass or block opponents while operating their vehicles at their traction limits. Racing simulations, such as the PlayStation game Gran Turismo, faithfully reproduce the non-linear control challenges of real race cars while also encapsulating the complex multi-agent interactions. Here we describe how we trained agents for Gran Turismo that can compete with the world’s best e-sports drivers. We combine state-of-the-art, model-free, deep reinforcement learning algorithms with mixed-scenario training to learn an integrated control policy that combines exceptional speed with impressive tactics.

In addition, we construct a reward function that enables the agent to be competitive while adhering to racing’s important, but under-specified, sportsmanship rules. We demonstrate the capabilities of our agent, Gran Turismo Sophy, by winning a head-to-head competition against four of the world’s best Gran Turismo drivers. By describing how we trained championship-level racers, we demonstrate the possibilities and challenges of using these techniques to control complex dynamical systems in domains where agents must respect imprecisely defined human norms.

What You’ll Learn: We demonstrate the possibilities and challenges of using deep RL techniques to control complex dynamical systems in domains such as Gran Turismo where agents must respect imprecisely defined human norms.

Jinen Setpal

Machine Learning Engineer, DagsHub

I’m a second-year undergraduate studying Data Science at Purdue University. I also work part-time as a Machine Learning Engineer @ DagsHub.

I love research – especially within academia! My interests lie firmly within Machine Vision, NLP & Cybersecurity; so far, I’ve published some peer-reviewed papers and have pending patents within these domains.

Talk: Interpretability Tools are Feedback Loops

Abstract: Fundamentally – Machine Learning as a field is designed to emulate the way humans think; hence, *neural* networks. When we train our models, we use optimizers and loss functions to measure their success. While these functions make sense mathematically, they are far from intuitive or explaining what happened behind the scenes. It’s hard to pick the correct functions, and performing huge grid searches to hyperparameter tune at scale is as logical as bruteforcing an SHA-256 hash.

On the other hand – Interpretability techniques can’t really be used in a training context but are intuitive in helping us understand how a given model interprets a set of data.

This talk aims to bridge the gap between the two, connecting them within a single training loop to maximize training effectiveness without disproportionately increasing compute or training time. Making training intuitive to how humans learn should help develop models that actually work, without resorting to “useless” training.

I aim to showcase – with a practical demonstration – learning techniques to build feedback loops wherein interpretability is used to better optimize a training sequence. I also aim to discuss how this carries forward to complex architectures, and a potential approach for their relevant implementation.

Structurally: the talk would provide an overview on machine interpretability, provide a brief overview on optimizers and loss functions before jumping into the implementation walkthrough of a case study. The case study uses TensorFlow, but can generally be applied to any desired framework.

What You’ll Learn: If, by the end my presentation, attendees are able to identify techniques for applying the proposed approach within their internal systems, or find themselves motivated to further research the ideas presented, I’d consider the talk a success.

Are there any industries (in particular) that are relevant for this talk?
Computer Software, Researchers within Academia

Who is this presentation for?
Data Scientists/ ML Engineers, ML Engineers, Researchers

What you’ll learn:
Most guides on Interpretable Machine Learning, while focusing on the seemingly black-box nature of models, fail to address the challenge of it only working post-training. It’s addressed as a final check tool to ensure it isn’t learning tragically differently from what the researcher expects, but not directly as part of the training feedback loop. I aim to address this.

What are the main core message (learning) you want attendees to take away from this talk?
If, by the end my presentation, attendees are able to identify techniques for applying the proposed approach within their internal systems, or find themselves motivated to further research the ideas presented, I’d consider the talk a success.

Pre-requisite Knowledge:
It’s a technical presentation, and requires participants to be familiar on a high level with model optimization techniques and machine interpretability. They should also be very familiar with the standard classification pipeline of a feedforward neural network.

What is unique about this speech, from other speeches given on the topic?
I work extensively on ML Reproducibility. In fact, it is the fundamental work done within my research grant funded by Google. Time and again, I find that papers tend to document the end-result and the problem statement extensively, but not everything in between. That’s where the real learning takes place, understanding what DIDN’T work and WHY.

This is rarely ever documented. Papers list working parameters, both functions and hyperparameters, but fail to explain why. I’ve struggled a lot with this and hope to relay potential solutions through the extent of my presentation.

Talk: The Risks of Excluding the Disengaged From your Dataset

Abstract: Analysts use machine learning tools to analyze the vast amounts of data now available. Big data is appealing, but even the best tools and techniques will give you noise if the underlying data aren’t robust and inclusive. To reliably predict elections, correctly anticipate consumer demand or to accurately predict the trajectory of a pandemic, leaders need to ask themselves who is (and isn’t) included in their dataset.

What You’ll Learn: There is a huge emphasis on tools to analyze big data but we need to spend at least as much time on the quality of the underlying dataset. If, for example, we exclude disengaged populations, as some common methods do, we risk getting things wrong, whether understanding a market’s potential, predicting an election result, or anticipating the trajectory of the pandemic, the war, or the economy.

Shiming Ren

Senior Engineering Manager – Safety, MLOps and Infrastructure, Amazon/Twitch

I worked as a Software Engineer Manager at Twitch about MLOps and Tooling in Safety team. Here is my linkedin. I spoke at Meta’s At Scale about Scaling ML Workflows for Real-Time Moderation Challenges at Twitch, I also spoke at TwitchCon about Integrating Data into Twitch at Scale. I worked in engineering leadership role for 5 years and our team made several company wide MLOps tooling such as orchstration and feature store.

Co-Presenter: Chen Liu

Talk: From Silo to Collaboration – Building Tooling to Support Distributed ML Teams at Twitch

Abstract: In this talk, we will cover Twitch’s current ML team structure and challenges of it. Then we dive deep into some solutions we have built to support ML development at Twitch, including what they are and how they will benefit the situation. We close with a discussion of Twitch’s distributed ML team style and how we collaborate using Conductor as an example.

ML has been playing a more and more important role in Twitch’s products (e.g. Recommendation, Safety). In order to allow products to iterate fast, we keep ML practitioners in the product teams and empower the teams to work independently. Undoubtedly, there are common challenges in ML development regardless of product areas. So we are striving to develop tooling and infrastructures for general ML development in order to reduce duplicate work across ML teams. We will dive into those efforts we made in this presentation. For example, Twitch machine learning feature store is developed to have a single control plane serving as feature registry but facilitates distributed feature ownership (e.g. storage, pipelines). Conductor, a in-house ML orchestration system, promotes best practices in pipeline management with templated process control flow and distributed infrastructure management. Meanwhile, we are promoting collaborative ML culture among Twitch engineering teams. It is similar to community owned open source projects where teams share the same interests and encourage cross team contribution and development.

What You’ll Learn: Twitch’s strategy of scaling our ML infra and MLOps tooling has never been discussed online. And we aim to help audience figure out the best strategy to utilize ML tooling for enhancing collaborations between ML teams and boost scientists self-service / efficiency. This is a good lesson if companies are seeking to start MLOps from stratch.

Talk: Builidng a Fully Automated ML Platform Using Kubeflow and Declarative Approach to Development of End-to-End ML Pipelines

Abstract: Recent innovations in the ML ecosystem have seen the emergence of operationally-focused technology like declarative systems and data-centric AI. These techniques appear to be a radical change for AI practitioners, who can now more simply frame use cases and manage workflows. In this talk, we’ll take a look at the history of AI to see the progress that has been made and how we’ve arrived at where we are now. How are high-tech companies handling AI initiatives internally, and why aren’t we all copying them? Has MLOps been the promised solution to simplifying deployment and monitoring of production AI? How do we create a simpler paradigm for operationalizing AI? All these questions and more will be addressed.

What You’ll Learn: A journey to higher levels of MLOps maturity is unique for any company and has no recipes due to experimental nature of MLOps. Many insights and ideas in this area are the results of investments by big names (Google, Microsoft, Amazon) and knowledge sharing between smaller companies like us working on similar problems. We are grateful for this opportunity to contribute to the ecosystem so that others can learn from us.

Eric is a Staff Data Scientist with more than 7 years of experience working at Altair Engineering and Anheuser-Busch. He has a PhD in probability from the University of Toronto, and a masters degree in Applied Math and an undergraduate degree in Engineering from Queen’s university. He’s also a world champion Blokus player.

Talk: Optimal Beer Pricing: An Optimization Layer for Price Elasticities

Abstract: At Anheuser-Busch, we’re obsessed with price elasticities. When the price of beer changes, how will that affect the volume of beer that we sell? These questions (yes, this is more than one question) have implications all over the business, from price setting to procurement to financial planning. We’ve worked hard to make sure our answers to these questions are as data driven as possible. But once we have a model to produce (and predict) these elasticities, how do we make business decisions based on that? And how do we make sure those business decisions are also as data driven as possible?

In this talk we’ll discuss an optimal pricing layer for beer elasticities. We’ll cover how to use mathematical optimization to make specific price change suggestions at a variety of granularities to help achieve specific business objectives. We’ll consider what objective we actually want to optimize (Profit? Revenue? Market Share?) and see how to use constraints to help smooth the trade-off between these objectives. Finally, we’ll investigate how to ensure our price suggestions stay within the regions where the underlying elasticities models make sense.

Ever wanted to see a real-world example of levelling up your analytics from predictive- to prescriptive-, and do so in the context of price setting (or beer drinking)? Now’s your chance!

What you’ll learn:
Putting a mathematical optimization layer on top of predictive models is still a mostly unused tool in the ML space. It’s very difficult to learn about that from existing resources.

What are the main core message (learning) you want attendees to take away from this talk?
How to add an optimization layer to ml models.

Pre-requisite Knowledge:
Not a lot. We’ll briefly discuss what price-elasticities and mathematical optimization are, but having heard those terms before (with a basic understanding) would help.

What is unique about this speech, from other speeches given on the topic?
I would argue the whole topic is fairly unique (optimization layers for predictive models are not widely used or discussed). In addition, the specifics of trying to work around the realities of the beer industry (especially varying laws about beer pricing across different geographies) add an extra layer of complexity to this already deep problem.

Talk: Solving Product Substitutions, The #1 Problem in Grocery E-Commerce – Through Self-Supervised ML

Abstract:
Background: Loblaw Companies Ltd is the largest grocery retailer in Canada. It operates multiple popular banners with Real Canadian Superstore, No Frills, and T&T being some of the most popular ones. E-commerce of grocery has become a significant part of the business accounting for more than $2 billion in sales per year.

Problem: Shopping for groceries online is an inherently different process than shopping in person. We take for granted the in-store shopper’s ability to make quick decisions on the fly when faced with the issue of product availability.

We fulfill from stores to ensure freshness which has a very dynamic inventory. This makes promises of items collected, sometimes a day or two after the order depending on the customer’s delivery date, affected by many factors – some of which we cannot control. Thus, we need a solution to substitute items that are out of stock at the time of picking to make sure the customer experience is minimally impacted. While shopping at a physical store, a customer can make a suitable choice of an alternative. In the e-commerce process of grocery shopping, either the customer has to make a selection of the substitute, or the Loblaw employee picking the order on behalf of the customer needs a relevant suggestion on the best substitute for the given item, personalized for the given customer.

Loblaw has historical data available on what selection was made by customers from the list of various possible substitute options available for a given item. Additionally, there is data available on the choices made by pickers – the employees who shop at the store to fulfill customers’ orders. This provides us an opportunity to tailor product similarities toward product substitutions that are tied to business metrics.

Solution: We explored multiple solutions to solve this problem. Our most promising solution that we wish to present leverages features extracted from text descriptions and images of products. In this talk, we will discuss how our approach evolved over time and how this cutting-edge self-supervised method is a big improvement over the traditional techniques.

What You’ll Learn: The talk covers the data curation process by which we prepared a benchmarking Products Substitutions dataset using historical human-selected substitutions data at Loblaw.

The audience will learn about self-supervised ML approaches we used to recommend product substitutions benchmarked against the above mentioned products substitutions Testset.

Quoc Tien Au

Data Scientist, Manifest Climate

I am a data scientist at Manifest Climate, working on applying machine learning and natural language processing to climate disclosures. Extracting information at scale is paramount to increase transparency in financial markets, so that we can improve decision-making with data-driven climate information.

Talk: Assessing Alignment of Climate Disclosures Using NLP for the Financial Markets

Abstract: Climate-related disclosure is increasing in importance as companies and stakeholders alike aim to reduce their environmental impact and exposure to climate-induced risk. Companies primarily disclose this information in annual or other lengthy documents where climate information is not the sole focus. To assess the quality of a company’s climate-related disclosure, these documents, often hundreds of pages long, must be reviewed manually by climate experts. We propose a more efficient approach to assessing climate-related financial information. We construct a model leveraging TF-IDF, sentence transformers and multi-label k nearest neighbors (kNN). The developed model is capable of assessing alignment of climate disclosures at scale, with a level of granularity and transparency that will support decision-making in the financial markets with relevant climate information.

What You’ll Learn: How an early-stage startup runs machine learning experiments ; takes decisions balancing model performance, model explainability, resource constraints and added business value ; uses deep language models to create the most valuable business opportunities.

What is unique about this speech, from other speeches given on the topic?
In my knowledge there is no company in North America doing data science/ML in parking industry. The problems we are solving are present in other industries but parking adds another layer of complexity on top of it.

Abstract of Talk:
SpotHero is the biggest and fastest growing off-street reservation platform in North America. It is a two sided marketplace involving drivers and parking garage owners. The data science team at SpotHero is working on many interesting problems in the areas of dynamic pricing, marketing, ranking etc. One of the key challenges that we face is how we test our machine learning models in production and make sure that the changes we make lead to an improvement in our KPI’s. In this talk, I will focus on how SpotHero runs experiments whenever we make improvements or create a new model to generate prices for our parking spots. I will cover why the general A/B test framework will not work in our scenario, various approaches that we considered and introduce switchback experimentation as an alternative. I will discuss our experiment design and conclude the talk with a result from one of our experiments and our technical architecture.

Can you suggest 2-3 topics for post-discussion?

Case Study

Technical level of your talk?
(Technical level: 6/7)

What you’ll learn:
The insights and findings we share in this talk are derived from using the latest ML techniques and tools for solving real-world use cases at SPINS and are not readily available on the internet. We also open the stage for Q&A at the end of this talk to address the questions from the audience.

Abstract of Talk:
In recent years, we have seen amazing results in artificial intelligence and machine learning owing to the emergence of models such as transformers and pretrained language models. Despite the astounding results published in academic papers, there remains a lot of ambiguity and challenges when it comes to deploying these models in the industry because 1) troubleshooting, training, and maintaining these models is very time and cost consuming due to their inherent large sizes and complexities 2) there is not yet enough clarity about when the advantages and challenges of these models outweigh classical ML models. These challenges are even more severe for small and mid-sized companies that do not have access to huge compute resources and infrastructure. In this talk, we discuss these challenges and share our findings and recommendations from working on real-world examples at SPINS, a data/tech company focused on the natural grocery industry. More specifically, we describe how we leverage state-of-the-art language models to seamlessly automate parts of SPINS’ data ingestion workflow and drive substantial business outcomes. We provide a walk-through of our end-to-end MLOps system and discuss how using the right tools and methods has helped to mitigate some of these challenges. We also share our findings from our experimentation and provide insights on when one should use these massive transformer models instead of classical ML models. Considering that we have a variety of challenges in our use cases from an ill-defined label space to a huge number of classes (~86,000) and massive data imbalance, we believe our findings and recommendations can be applied to most real-world settings. We hope that the learnings from this talk can help you to solve your own problems more effectively and efficiently!

Workshop: Beyond the Basics: Data Visualization in Python

Abstract: The human brain excels at finding patterns in visual representations, which is why data visualizations are essential to any analysis. Done right, they bridge the gap between those analyzing the data and those consuming the analysis. However, learning to create impactful, aesthetically-pleasing visualizations can often be challenging. This session will equip you with the skills to make customized visualizations for your data using Python.

While there are many plotting libraries to choose from, the prolific Matplotlib library is always a great place to start. Since various Python data science libraries utilize Matplotlib under the hood, familiarity with Matplotlib itself gives you the flexibility to fine tune the resulting visualizations (e.g., add annotations, animate, etc.). This session will also introduce interactive visualizations using HoloViz, which provides a higher-level plotting API capable of using Matplotlib and Bokeh (a Python library for generating interactive, JavaScript-powered visualizations) under the hood.

What You’ll Learn: Data visualization is essential for anyone working with data, but sometimes it can be difficult to create impactful visualizations in Python. In this workshop, we will move beyond the plotting basics and explore how to make compelling static, animated, and interactive visualizations.

Workshop (1.5-4 hours)

Technical level of your talk?
(Technical level: 4/7)

Who is this presentation for?
Data Scientists/ ML Engineers, ML Engineers, Researchers

What you’ll learn:
A workshop provides the attendees opportunities to ask questions to make sure they are understanding the concepts. Attendees will also have a workshop of curated examples using real-world data rather than the dummy or randomly-generated data nearly everywhere. Each of the visualizations is also created step-by-step, viewing how it changes with each command, which gives attendees a much stronger grasp of the concepts that they can apply elsewhere.

What are the main core message (learning) you want attendees to take away from this talk?
Data visualization is essential for anyone working with data, but sometimes it can be difficult to create impactful visualizations in Python. In this workshop, we will move beyond the plotting basics and explore how to make compelling static, animated, and interactive visualizations.

Pre-requisite Knowledge:
You should have basic knowledge of Python and be comfortable working in Jupyter Notebooks. Check out this notebook for a crash course in Python or work through the official Python tutorial for a more formal introduction. The environment we will use for this workshop comes with JupyterLab, which is pretty intuitive, but be sure to familiarize yourself using notebooks in JupyterLab and additional functionality in JupyterLab. In addition, a basic understanding of pandas will be beneficial, but is not required; reviewing the first section of my pandas workshop will be sufficient.

What is unique about this speech, from other speeches given on the topic?
My teaching style is very different: since the code examples I provide are carefully chosen, it’s easy to see why would take the approach I show, so I make sure that the attendees understand exactly what each line of code is doing to make that happen. I find that this gives the attendees knowledge that they can apply to other problems, rather than just knowing that the code all together has some effect — they get a deeper understanding and can use the concepts like building blocks for their own use cases. Attendees often praise the content in the slides as a detailed reference for later as well.

Some of the twists and turns will include:
– Integrating a BERT based model with a message queue system
– Speeding up semantic search through vectorization
– Enabling multi lingual recommendations

Each member of the talk will have access to the code examples and will be encouraged to think beyond the challenges addressed and how they can apply some of our lessons learned to their own work.

What You’ll Learn:
– How to go from idea to product
– How to iterate on a product
– How to go to production
– How to incorporate customer feedback

Workshop: Open Source Intelligent Application Delivery on Kubernetes

Abstract: The recent rise in popularity of containerized workloads demanded better ways to orchestrate and manage these workloads hence the creation of the Kubernetes platform.

When it comes to running intelligent application workloads which contain built-in AI/ML software components, the requirement of a Kubernetes platform as a service extends beyond agility, portability, flexibility and scalability as it is required to also answer to the datascientist’s dilemma: getting started and getting into production.

However, as the ML code is only a small part of the entire intelligent application ecosystem, with this workshop we present a showcase for using a Kubernetes platform and a blueprint architecture that proposes an answer to many challenges related to the development, deployment and management of distributed applications.
The user stories we shall focus on in this workshop concerning the developer, data scientist and operations engineer personas are:
– As a data scientist, I want to develop ML models using Jupyter Hub (lab/notebooks) as my preferred research environment.
– As a data scientist, I want my model to be deployed quickly so that it may be used by other applications.
– As a (fullstack) developer, I want to have quick access to resources that support the business logic of my applications, including databases, storage, messaging.
– As a (fullstack) developer, I want an automated build process to support new releases/code updates as soon as they are available in a git repository.
– As an operations engineer, I want an integrated monitoring dashboard to new applications available on the (production) infrastructure.

What You’ll Learn: Open source container platforms are a great option to integrate Machine Learning with any application or service by boosting productivity while maintaining a high level of security.

Abstract of Talk:
Many Machine Learning fail to turn an initial idea and potentially even first model into the business impact, as they neglect the importance (and associated work) of building a production-grade ML pipeline. There are many great tutorials for training your deep learning models using PyTorch, TensorFlow, Keras, Spark or one of the many other frameworks. But training is only a small part in the overall deep learning pipeline. This workshop gives an overview into building a complete automated deep learning pipeline starting with exploratory analysis, over training, model storage, model serving, meta-data storage, and monitoring using available Open-Source tool.

The participants will build an end-to-end data analytics pipeline including:
– Pipeline Orchestration
– Data preparation using Apache Spark
– Jupyter Notebooks
– Distributed training with TensorFlow
– Automation & CI/CD using Jenkins and Argo
– Model and metadata storage
– Model serving and monitoring

Workshop: Learning Embedded Representation of the Stock Correlation Matrix using Graph Machine Learning

Abstract: Understanding non-linear relationships among financial instruments has various applications in investment processes ranging from risk management, portfolio construction and trading strategies. Here, we focus on interconnectedness among stocks based on their correlation matrix which we represent as a network with the nodes representing individual stocks and the weighted links between pairs of nodes representing the corresponding pair-wise correlation coefficients. The traditional network science techniques, which are extensively utilized in financial literature, require handcrafted features such as centrality measures to understand such correlation networks.

However, manually enlisting all such handcrafted features may quickly turn out to be a daunting task. Instead, we propose a new approach for studying nuances and relationships within the correlation network in an algorithmic way using a graph machine learning algorithm called Node2Vec.

In particular, the algorithm compresses the network into a lower dimensional continuous space, called an embedding, where pairs of nodes that are identified as similar by the algorithm are placed closer to each other. By using log returns of S&P 500 stock data, we show that our proposed algorithm can learn such an embedding from its correlation network. We define various domain specific quantitative (and objective) and qualitative metrics that are inspired by metrics used in the field of Natural Language Processing (NLP) to evaluate the embeddings in order to identify the optimal one. Further, we discuss various applications of the embeddings in investment management.

What You’ll Learn: In this paper we have shown how to create stock embedding representation from stock correlation matrix. And evaluated the learnt embeddings using a quantitative way

Workshop

What you’ll learn:
What drift detection is, why it’s important and how to get started.

Pre-requisite Knowledge:
No prior knowledge or understanding of drift detection is required (we’ll be covering that) but a basic knowledge of machine learning and some experience with Python will be helpful.

Abstract of Talk:
Although powerful, modern machine learning models can be sensitive. Seemingly subtle changes in a data distribution can destroy the performance of otherwise state-of-the art models, which can be especially problematic when ML models are deployed in production. In this workshop, we will give a hands-on overview to drift detection, the discipline focused on detecting such changes. We will start by building an understanding of the ways in which drift can occur, and why it pays to detect it. We’ll then explore the anatomy of a drift detector, and learn how they can be used to detect drift in a principled manner.

You will work through a real-world example using Alibi Detect, an open-source Python library offering powerful algorithms for adversarial, outlier and drift detection.You’ll learn how to set-up drift detectors, and deduce what type of drift is occurring. Since data can take many forms, such as image, text or tabular data, you’ll explore how to use existing ML models to pre-process your data into a form suitable for drift detectors. Then, to gain further insights into the causes of drift, you’ll employ state-of-the art detectors which are able to perform fine-grained attribution to instances and features. To assess whether model performance has been affected by drift, you’ll experiment with using model uncertainty based detectors. Finally, you’ll use a novel context-aware drift detector. This takes in context (or conditioning) variables, allowing you to test for drift conditional on context that is permitted to change. We’ll discuss how this functionality can be crucial in many real-world drift detection scenarios.

This hands-on workshop is targeted at a beginner-intermediate level. No prior knowledge or understanding of drift detection is required (we’ll be covering that) but a basic knowledge of machine learning and some experience with Python will be helpful.

The workshop will be hands-on based on Jupyter notebooks and cover sessions

What you’ll learn:
This session will explore the steps you can take to prepare for ML observability. We will also discuss how observability helps data scientists and MLOps practitioners showcase the business value of the applications they deploy and get recognition for their hard work.

Abstract of Talk:
MLOps is bringing a lot of attention to the business impact of Machine Learning. It also introduces new challenges that cannot be efficiently addressed with DevOps. What are these challenges, and what makes MLOps so different from DevOps? They both deal with the life cycle of an application, so what is the difference? Most software applications have a pre-defined behavior. We know the data going in, and we know the data going out. Anything not matching a predefined format or schema is a problem. Machine Learning models follow the same pattern to operate, but their value diminishes as the content of the data changes. We are looking at the schema, format, and patterns describing a change in the data. This is the big difference between DevOps and MLOps, observing the data.

Most organizations have focused on the simplification, automation, and scalability of Machine Learning applications. Observability has taken a back seat. This session will explore the steps you can take to prepare for ML observability. We will also discuss how observability helps data scientists and MLOps practitioners showcase the business value of the applications they deploy and get recognition for their hard work.

Lightning Ignite Talk

Abstract of Talk:
The financial and business community have already caught on to the essential importance of sustainability. Investors now call for better practices and reporting on Environment, Social, and Governance, or ESG performance metrics. According to Bloomberg Intelligence, growth in ESG investing is fast becoming the new norm, with ESG investments projected to exceed USD 50 trillion by 2025 – more than 1/3 of all global assets under management. This movement of funds to ESG represents a massive, once-in-a-generation transition to an entirely new economy.

Sustainability is incredibly complex, involving billions of moving parts and decisions. It starts at the edge, where exabytes of data are flowing from real-time sensors and controls in factories and power plants, which aggregate up to the top-level decision makers in companies, which aggregate up to the massive funds that hold portfolios of those companies, and to government regulators and policymakers. AI is critical in analyzing those exabytes of data and enables closed-loop optimization to reduce energy, water, and waste.

In this session, we’ll explore the top 3 needs and opportunities for AI to catalyze change toward more sustainable companies, economies, and societies.
