tf.contrib.layers.l2_regularizer()

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

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

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.
