.SH DESCRIPTION


This utility takes a dataset and a \fIvector\fP of indices and does one-hot encoding
of the respective features at those indices. Indices represent the IDs of the
dimensions to be one-hot encoded.
.PP
The output matrix with encoded features may be saved with the '\fB--output_file\fP
(\fB-o\fP)' parameters.
.PP
So, a simple example where we want to encode 1st and 3rd feature from dataset
\(cqX.csv' into 'X_output.csv' would be
.PP
$ \fBmlpack_preprocess_one_hot_encoding\fP \fB--input_file\fP X.csv \fB--output_file\fP
X_ouput.csv \fB--dimensions\fP 1 \fB--dimensions\fP 3
