tf.train.sdca_shrink_l1(
    weights,
    l1,
    l2,
    name=None
)

Defined in tensorflow/python/ops/gen_sdca_ops.py.

Applies L1 regularization shrink step on the parameters.

Args:

• weights: A list of Tensor objects with type mutable float32. a list of vectors where each value is the weight associated with a feature group.
• l1: A float. Symmetric l1 regularization strength.
• l2: A float. Symmetric l2 regularization strength. Should be a positive float.
• name: A name for the operation (optional).

Returns:

The created Operation.
