Documentation

DataSet where data is fully loaded in memory.

Inputs and targets are put in two arrays: inputs_array and targets_array. You can fill these fields by using the init() method (if you are using IOSequence). But you could imagine a MemoryDataSet where you fill these fields by hand (based on the init() method). MatDataSet is a good example if you plan to do a new MemoryDataSet.

Sequence** inputs_array

Inputs array

Sequence** targets_array

Targets array

MemoryDataSet()

void init(IOSequence* io_inputs, IOSequence* io_outputs)

May help you to initialize the DataSet if you're using IOSequence. You should call this method in the constructor of your subsclasses. Initialize n_examples, n_real_examples, n_inputs and n_targets. inputs_array and targets_array filled with sequences given by the IOSequence classes.

void setInputs(Sequence** inputs_, int n_sequences_)

Override current inputs array

void setTargets(Sequence** targets_, int n_sequences_)

Override current targets array
