tf.contrib.layers.l1_regularizer()

tf.contrib.layers.l1_regularizer(scale, scope=None)

Returns a function that can be used to apply L1 regularization to weights.

L1 regularization encourages sparsity.

Args:

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

Returns:

A function with signature l1(weights) that apply L1 regularization.

Raises:

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