Distributed Machine Learning with confidence

Contemporary machine learning generally output point predictions, with predictive accuracy measured on an external test set or using cross-validation. This unavoidably leads to discussion of a model's "applicability domain", which is a fuzzy concept without stringent definition.

In this project we develop methods for enabling distributed machine learning based on Conformal Prediction theory, delivering prediction intervals instead of point predictions, implemented in the Big Data framework Apache Spark. We apply the methods primarily on drug discovery data in collaboration with partners at AstraZeneca R&D and SweTox.
