DeepLearning4J (DL4J) is one of the most used opensource library in machine learning. It can be found at https://deeplearning4j.org/.
The best description for this library is available on its website, which says—Deeplearning4j is the first commercial-grade, open-source, distributed deep learning library written for Java and Scala. Integrated with Hadoop and Apache Spark, DL4J brings AI to business environments for use on distributed GPUs and CPUs.
In this recipe, we will see how it's possible to use Elasticsearch as a source for data to be trained in a machine learning algorithm.
