Method Detail

fetch

public void fetch(int numExamples)

Description copied from interface: DataSetFetcher

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

Parameters:

numExamples - the number of examples to fetch

next

public org.nd4j.linalg.dataset.DataSet next()

Description copied from interface: DataSetFetcher

Returns the next data applyTransformToDestination

Specified by:

next in interface DataSetFetcher

Overrides:

next in class BaseDataFetcher

Returns:

the next dataset
