NAME¶

SYNOPSIS¶

 mlpack_preprocess_split [-h] [-v]  

DESCRIPTION¶

The program does not modify the original file, but instead makes separate files to save the training and test files; The program requires you to specify the file names with --training_file (-t) and --test_file (-T).

Optionally, labels can be also be split along with the data by specifying the --input_labels_file (-I) option. Splitting labels works the same way as splitting the data. The output training and test labels will be saved to the files specified by --training_labels_file (-l) and --test_labels_file (-L), respectively.

So, a simple example where we want to split dataset.csv into train.csv and test.csv with 60% of the data in the training set and 40% of the dataset in the test set, we could run

$ mlpack_preprocess_split -i dataset.csv -t train.csv -T test.csv -r 0.4

If we had a dataset in dataset.csv and associated labels in labels.csv, and we wanted to split these into training_set.csv, training_labels.csv, test_set.csv, and test_labels.csv, with 30% of the data in the test set, we could run

$ mlpack_preprocess_split -i dataset.csv -I labels.csv -r 0.3 > -t training_set.csv -l training_labels.csv -T test_set.csv > -L test_labels.csv
