SYNOPSIS

9        mlpack_preprocess_imputer [-h] [-v]
10

DESCRIPTION

12       This utility takes a dataset and converts user defined missing variable
13       to another to provide more meaningful analysis
14
15       The program does not modify the original file, but instead makes a sep‐
16       arate file to save the output data; You can save the output by specify‐
17       ing the file name with --output_file (-o).
18
19       For example, if we consider 'NULL' in dimension 0 to be a missing vari‐
20       able  and  want  to delete whole row containing the NULL in the column-
21       wise dataset, and save the result to result.csv, we could run
22
23       $ mlpack_preprocess_imputer -i dataset.csv -o result.csv -m NULL -d 0 >
24       -s listwise_deletion
