tf.keras.backend.bias_add

tf.keras.backend.bias_add(
    x,
    bias,
    data_format=None
)

Defined in tensorflow/python/keras/_impl/keras/backend.py.

Adds a bias vector to a tensor.

Arguments:

  • x: Tensor or variable.
  • bias: Bias tensor to add.
  • data_format: string, "channels_last" or "channels_first".

Returns:

Output tensor.

Raises:

  • ValueError: In one of the two cases below: 1. invalid data_format argument. 2. invalid bias shape. the bias should be either a vector or a tensor with ndim(x) - 1 dimension
