CMLPDataFile Class Reference

Detailed Description

MLPDataFile = CSV in a binary format.

The byte order is Little-Endian.

Format:

int - NIn (only for Alglib_MultilayerPerceptron and Alglib_RandomForest)
int - NOut (only for Alglib_MultilayerPerceptron and Alglib_RandomForest)
int - header size
   if (header size > 0) {
      int - length of string
      byte[] - UTF-16LE
      ...
   }
int - data size
double[data size] - data array
...
