tf.contrib.layers.l2_regularizer

Returns a function that can be used to apply L2 regularization to weights.

tf.contrib.layers.l2_regularizer(
    scale,
    scope=None
)

Defined in contrib/layers/python/layers/regularizers.py.

Small values of L2 can help prevent overfitting the training data.

Args:

  • scale: A scalar multiplier Tensor. 0.0 disables the regularizer.
  • scope: An optional scope name.

Returns:

A function with signature l2(weights) that applies L2 regularization.

Raises:

  • ValueError: If scale is negative or if scale is not a float.
