Karthikeya Sampa Subbarao: Large-scale elastic machine learning using sparse grid combination technique

Large scale machine learning (ML) often requires flexible specification of ML algorithms for dynamic scaling, depending on the availability of resources. In this work, we introduce a grid-based ensemble technique for regression, which provides the foundation for a framework capable of dynamic resource utilization and fault tolerance. We also introduce a technique based on gradient boosting for efficient selection of grids for refinement.
