The O’Reilly Data Show Podcast: Jason Dai on BigDL, a library for deep learning on existing data frameworks.
In this episode of the Data Show, I spoke with Jason Dai, CTO of big data technologies at Intel, and co-chair of Strata + Hadoop World Beijing. Dai and his team are prolific and longstanding contributors to the Apache Spark project. Their early contributions to Spark tended to be on the systems side and included Netty-based shuffle, a fair-scheduler, and the “yarn-client” mode. Recently, they have been contributing tools for advanced analytics. In partnership with major cloud providers in China, they’ve written implementations of algorithmic building blocks and machine learning models that let Apache Spark users scale to extremely high-dimensional models and large data sets. They achieve scalability by taking advantage of things like data sparsity and Intel’s MKL software. Along the way, they’ve gained valuable experience and insight into how companies deploy machine learning models in real-world applications.
When I predicted that 2017 would be the year when the big data and data science communities start exploring techniques like deep learning in earnest, I was relying on conversations with many members of those communities. I also knew that Dai and his team were at work on a distributed deep learning library for Apache Spark. This evolution from basic infrastructure, to machine learning applications, and now applications backed by deep learning models is to be expected.
Once you have a platform and a team that can deploy machine learning models, it’s natural to begin exploring deep learning. As I’ve highlighted in recent episodes of this podcast (here and here), companies are beginning to apply deep learning to time-series data, event data, text, and images. Many of these same companies have already invested in big data technologies (many of which are open source) and employ data scientists and data engineers who are comfortable with these tools.
