Project Hydrogen: Unifying State-of-the-Art AI and Big Data in Apache Spark

Speaker: Tim Hunter, Databricks

Big data and AI are joined at the hip: the best AI applications require massive amounts of constantly updated training data to build state-of-the-art models AI has always been on of the most exciting applications of big data and Apache Spark. Increasingly Spark users want to integrate Spark with distributed deep learning and machine learning frameworks built for state-of-the-art training. On the other side, increasingly DL/AI users want to handle large and complex data scenarios needed for their production pipelines.

This talk introduces a new project that substantially improves the performance and fault-recovery of distributed deep learning and machine learning frameworks on Spark. We will introduce the major directions and provide progress updates, including 1) barrier execution mode for distributed DL training, 2) fast data exchange between Spark and DL frameworks, and 3) accelerator-awareness scheduling.

Bio: Timothy Hunter received the diplôme d'ingénieur from École Polytechnique in 2007, the M.S. degree in electrical engineering from Stanford University in 2009 and the Ph.D. degree in computer science from the University of California at Berkeley in 2014. He is currently a software engineer at Databricks and contributes to the Apache Spark MLlib project, as well as the GraphFrames, TensorFrames and Deep Learning Pipelines libraries. He has been building distributed Machine Learning systems with Spark since version 0.0.2, before Spark was an Apache Software Foundation project.
