MovingWindowDataSetFetcher

public MovingWindowDataSetFetcher(org.nd4j.linalg.dataset.DataSet data,
                                  int windowRows,
                                  int windowColumns)

Method Detail

fetch

public void fetch(int numExamples)

Fetches the next dataset. You need to call this to getFromOrigin a new dataset, otherwise BaseDataFetcher.next() just returns the last data applyTransformToDestination fetch

Parameters:

numExamples - the number of examples to fetch
