**What it does**

Converts a class vector (integers) to binary class matrix.

tf.keras.utils.to_categorical(
    y, num_classes=None, dtype='float32'
)

E.g. for use with categorical_crossentropy.

Arguments

y: a vector of numbers to be converted into a matrix of one-hot encoded values.
num_classes: total number of classes. If None, this would be inferred as the (largest number in y) + 1.
dtype: The data type expected by the input. Default: 'float32'.

Returns

A binary matrix representation of the input. The classes axis is placed last.

Raises

Value Error: If input contains string value
