Learn how to get started with distributed Deep Learning library BigDL for Apache Spark. You will also see demo of a Deep Learning application that uses BigDL running on a Spark cluster. The application is written to identify handwritten digits (0 to 9) using a LeNet-5 (Convolutional Neural Networks) model that is trained and validated using MNIST database.

Distributed deep learning library for Apache Spark Open sourced by Intel (in Dec 2016) Feature parity with DL frameworks such as Caffe, Torch Integrates with Spark ML pipeline and Spark Streaming Supports Model snapshots Intel MKL (Math Kernel Library); multi-threading within each Spark task

- 12. Copyright 2017 © Qubole BigDL vs TensorFrames TensorFrames — can call TF from individual partitions of a DataFrame or an RDD (in PySpark)… However, since TF is not natively integrated with Spark, it does not support distributed deep learning such as for model training or fine tuning.
- 13. Copyright 2017 © Qubole BigDL vs TensorFlow on Spark (TFOS), Caffe TensorFlow on Spark* (TFOS) and Caffe on Spark — use Spark executors to launch TF or Caffe instances on the cluster… However, model training, predictions, etc. are performed outside of Spark across multiple TF or Caffe instances… • Run as standalone jobs outside of the pipeline • Very fine-grained/limited interaction with analytics pipeline *Not to be confused with natively distributed TensorFlow by Google
