Building Explainable Machine Learning Systems: The Good, the Bad, and the Ugly

The good news is building fair, accountable, and transparent machine learning systems is possible. The bad news is it’s harder than many blogs and software package docs would have you believe. The truth is nearly all interpretable machine learning techniques generate approximate explanations, that the fields of eXplainable AI (XAI) and Fairness, Accountability, and Transparency in Machine Learning (FAT/ML) are very new, and that few best practices have been widely agreed upon. This combination can lead to some ugly outcomes! This talk aims to make your interpretable machine learning project a success by describing fundamental technical challenges you will face in building an interpretable machine learning system, defining the real-world value proposition of approximate explanations for exact models, and then outlining the following viable techniques for debugging, explaining, and testing machine learning models: *Model visualizations including decision tree surrogate models, individual conditional expectation (ICE) plots, partial dependence plots, and residual analysis. *Reason code generation techniques like LIME, Shapley explanations, and Treeinterpreter. *Sensitivity Analysis. Plenty of guidance on when, and when not, to use these techniques will also be shared, and the talk will conclude by providing guidelines for testing generated explanations themselves for accuracy and stability. Open source examples (with lots of comments and helpful hints) for building interpretable machine learning systems are available to accompany the talk at: https://github.com/jphall663/interpretable_machine_learning_with_python Bio: Patrick Hall is senior director for data science products at H2O.ai where he focuses mainly on model interpretability.
