Hosted By: Ben Lorica

Deep learning is a popular area of machine learning. Deep learning models that are used in practice for image classification and speech recognition contain a huge number of weights, require a lot of computations, and are trained with large datasets. Training such models might take days or even months on a single powerful machine, but ongoing research is exploring how to scale out the training by means of distributed computations and data processing. Since Apache Spark provides these capabilities, as well as many other useful libraries essential to analytics and machine learning, it is a strong contender for a distributed training platform for deep learning. Alexander Ulanov offers an overview of a number of different tools and frameworks that have been proposed for performing deep learning on Spark and compares them. Alexander also considers the limitations of distributed training itself in the context of Spark and modern hardware.
