Deep Mining : scaling Bayesian auto-tuning of data science pipelines

Within the automated machine learning movement, hyperparameter optimization has emerged as a particular focus. Researchers have introduced various search algorithms and open-source systems in order to automatically explore the hyperparameter space of machine learning methods. While these approaches have been effective, they also display significant shortcomings that limit their applicability to realistic data science pipelines and datasets. In this thesis, we propose an alternative theoretical and implementational approach by incorporating sampling techniques and building an end-to-end automation system, Deep Mining. We explore the application of the Bag of Little Bootstraps to the scoring statistics of pipelines, describe substantial asymptotic complexity improvements from its use, and empirically demonstrate its suitability for machine learning applications. The Deep Mining system combines a standardized approach to pipeline composition, a parallelized system for pipeline computation, and clear abstractions for incorporating realistic datasets and methods to provide hyperparameter optimization at scale.
