Running a CNN for learning MNIST with DeepLearning4j over Spark

In this recipe, we'll see how to run a CNN for classifying the iris dataset.

Getting ready

To step through this recipe, you will need a running Spark cluster either in pseudo distributed mode or in one of the distributed modes, that is, standalone, YARN, or Mesos. Also, get familiar with ND4S, that is, n-dimensional arrays for Scala (Scala bindings for ND4J). ND4J and ND4S are scientific computing libraries for the JVM. Please visit http://nd4j.org/ for details. The prerequisites to be installed are Java 7, IntelliJ, and the Maven or SBT build tool.

How to do it…

  1. The MNIST database is a large set of handwritten digits used to train neural networks and other algorithms in image recognition. ...
