Aliases:

    y,
    num_classes=None,
    dtype='float32'
)

Used in the guide:

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.
