The Case for Model Debugging

Abstract: Prediction by machine learning models is fundamentally the execution of computer code. Like all good code, machine learning models should be debugged for logical or runtime errors or for security vulnerabilities. Recent, high-profile failures have made it clear that machine learning models must also be debugged for disparate impact across demographic segments and other types of sociological bias. Model debugging enhances trust in machine learning directly by increasing accuracy in new or holdout data, by decreasing or identifying hackable attack surfaces, or by decreasing sociological bias. As a side-effect, model debugging should also increase understanding and explainability of model mechanisms and predictions. This presentation outlines several standard and newer model debugging techniques and proposes several potential remediation methods for any discovered bugs. Discussed debugging techniques include adversarial examples, benchmark models, partial dependence and individual conditional expectation, random attacks, Shapley explanations of predictions and residuals, and models of residuals. Proposed remediation approaches include alternate models, editing of deployable model artifacts, missing value injection, prediction assertions, and regularization methods.

Bio: Patrick Hall is the Senior Director of Product at H2O.ai where he focuses mainly on model interpretability. Patrick is also currently an adjunct professor in the Department of Decision Sciences at George Washington University, where he teaches graduate classes in data mining and machine learning. Prior to joining H2O.ai, Patrick held global customer-facing roles and research and development roles at SAS Institute.

Productionizing H2O Models with Apache Spark

Spark pipelines represent a powerful concept to support productionizing machine learning workflows. Their API allows to combine data processing with machine learning algorithms and opens opportunities for integration with various machine learning libraries. However, to benefit from the power of pipelines, their users need to have a freedom to choose and experiment with any machine learning algorithm or library. Therefore, we developed Sparkling Water that embeds H2O machine learning library of advanced algorithms into the Spark ecosystem and exposes them via pipeline API. Furthermore, the algorithms benefit from H2O MOJOs – Model Object Optimized – a powerful concept shared across entire H2O platform to store and exchange models. The MOJOs are designed for effective model deployment with focus on scoring speed, traceability, exchangeability, and backward compatibility. In this talk we will explain the architecture of Sparkling Water with focus on integration into the Spark pipelines and MOJOs. We’ll demonstrate creation of pipelines integrating H2O machine learning models and their deployments using Scala or Python. Furthermore, we will show how to utilize pre-trained model MOJOs with Spark pipelines.

Bio: Jakub (or “Kuba” as we call him) completed his Bachelor’s Degree in Computer Science and Master’s Degree in Software Systems at Charles University in Prague. As a bachelor’s thesis, Kuba wrote a small platform for distributed computing of any types of tasks. During his master’s degree studies, he developed a cluster monitoring tool for JVM based languages which makes debugging and reasoning the performance of distributed systems easier using a concept called distributed stack traces. Kuba enjoys dealing with problems and learning new programming languages. At H2O.ai, Kuba works on Sparkling Water.

Aside from programming, Kuba enjoys exploring new cultures and bouldering. He’s also a big fan of tea preparation and the associated ceremony.
