How to train a DeepLearning4j model with custom images. 'new File("directory")' is the directory wich has 1 subdirectory with images for each category you have.

train.java

RecordReader recordReader = new ImageRecordReader(Config.IMAGE_WIDTH, Config.IMAGE_HEIGHT, Config.CHANNELS, true);
recordReader.initialize(new FileSplit(new File("directory"), BaseImageLoader.ALLOWED_FORMATS));
DataSetIterator dataIter = new RecordReaderDataSetIterator(recordReader, batchSize, -1, numLabels);
while (dataIter.hasNext()) {
	dsNext = dataIter.next();
	dsNext.scale();

	network.fit(dsNext);
}
