class DiskDataSet

Provides an interface to manipulate all kind of data which are kept on disk, and not fully loaded in memory.

Inheritance:

Public Methods

DiskDataSet()

void init(IOSequence* io_inputs_, IOSequence* io_targets_)

This function has to be called by your sub-classes.

Documentation

Provides an interface to manipulate all kind of data which are kept on disk, and not fully loaded in memory. It uses IOSequence. Usefull for large databases. DiskMatDataSet is a good example if you plan to code a new DiskDataSet.

PreProcessingList* pre_processes

List if pre processes to do

IOSequence* io_inputs

IOMatrix which provides inputs

IOSequence* io_targets

IOMatrix which provides targets

DiskDataSet()

void init(IOSequence* io_inputs_, IOSequence* io_targets_)

This function has to be called by your sub-classes. You give here the IOMatrix which handle the inputs and the targets of your dataset. Should be called in the constructor of all yoyr sub-classes.
