tf.contrib.layers.l1_regularizer

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

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

See the guide: Layers (contrib) > Regularizers

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.
