Public Methods

[more] MatDataSet(const char* filename, int n_inputs_, int n_targets_, bool one_file_is_one_sequence=false, int max_load=-1, bool binary_mode=false)
Create a new dataset from the file filename.
[more] MatDataSet(char** filenames, int n_files_, int n_inputs_, int n_targets_, bool one_file_is_one_sequence=false, int max_load=-1, bool binary_mode=false)
Same as the previous constructor, but for several files.
[more] MatDataSet(char** input_filenames, char** target_filenames, int n_files_, int max_load=-1, bool binary_mode=false)
Here the inputs and the targets are in separated files.

Documentation

Matrix DataSet. The standard dataset, with data fully loaded in memory. Usefull for large databases.

o MatDataSet(const char* filename, int n_inputs_, int n_targets_, bool one_file_is_one_sequence=false, int max_load=-1, bool binary_mode=false)
Create a new dataset from the file filename. If the file contains only one sequence, set one_file_is_one_sequence to true. If there is several sequences, and you want only to load the first n ones, set max_load to n (else max_load should be a negative number). If binary_mode is true, the IOBin format will be used, else it will be the IOAscii format.

Input and target sequence will have the same number of frames. For each frame given by the dataset, the first n_inputs_ real are for the inputs and then the next n_targets_ real are for the targets. (n_inputs_ is the input frame size and n_targets_ is the target frame size).

o MatDataSet(char** filenames, int n_files_, int n_inputs_, int n_targets_, bool one_file_is_one_sequence=false, int max_load=-1, bool binary_mode=false)
Same as the previous constructor, but for several files. If one_file_is_one_sequence is true, each files will be considered as they had only one sequence.

o MatDataSet(char** input_filenames, char** target_filenames, int n_files_, int max_load=-1, bool binary_mode=false)
Here the inputs and the targets are in separated files. Input and target frame sizes are therefore auto-detected. One file must correspond to one sequence.
