read_labels_file(path, delim, encoding=`'utf-8'`)

source code

Reads the labels of each column in the training and test files (features and reference files).

Parameters:

path - the path of the labels file
delim - the character used to separate the label strings.
encoding - the character encoding used to read the file. Default is 'utf-8'.

Returns:

a list of strings representing each feature column.

read_reference_file(path, delim, encoding=`'utf-8'`)

source code

Parses the file that contains the references and stores it in a numpy array.

@param path the path of the file. @delim char the character used to separate values.

Returns:: a numpy array representing each instance response value

read_features_file(path, delim, encoding=`'utf-8'`)

source code

Reads the features for each instance and stores it on an numpy array.

Parameters:

path - the path to the file containing the feature set.
delim - the character used to separate the values in the file pointed by path.
encoding - the character encoding used to read the file.

Returns:

an numpy array where the columns are the features and the rows are the instances.
