Deeplearning4j - Apache Apex

This repository contains Apex Operators for training, evaluations and scoring of Deeplearning4j Models.

Deeplearning4j Scoring Operator

Operator Objective

Using Deeplearning models trained by Deeplearning4j for machine scoring of incoming tuples.

Properties of Deeplearning4j Scoring Operator

Property	Description	Type	Mandatory	Default Value
modelFilePath	Path where the model zip file is stored on hdfs. e.g. /user/ambarish/iris	String	YES	N/A
modelFileName	Name of the model file. e.g. iris.zip	String	YES	N/A

Ports

Port	Description	Type	Mandatory
input	Tuples to be scored by dl4j model are received at this port.	DataSet	Yes
scoredDataset	Scored Dataset will be emmited to this port.	DataSet	Yes
feedback	Model can be extended by giving labelled dataset on this port	DataSet	No

Example
