Converts a class vector (integers) to binary class matrix.
Aliases:
tf.keras.utils.to_categorical(
y,
num_classes=None,
dtype='float32'
)
E.g. for use with categorical_crossentropy.
Arguments:
y: class vector to be converted into a matrix (integers from 0 to num_classes).num_classes: total number of classes.dtype: The data type expected by the input. Default:'float32'.
Returns:
A binary matrix representation of the input. The classes axis is placed last.
