tfmri.convex.ConvexFunctionIndicatorBall

class ConvexFunctionIndicatorBall(domain_dimension, order, scale=None, dtype=None, name=None)

Bases: tensorflow_mri.python.ops.convex_ops.ConvexFunction

A ConvexFunction representing the indicator function of an Lp ball.

Parameters

• domain_dimension – A scalar integer tf.Tensor. The dimension of the domain.

• order – A float. The order of the norm. Supported values are 1, 2, np.inf.

• scale –

  A float. A scaling factor. Defaults to 1.0.

• dtype – A tf.dtypes.DType. The type of this ConvexFunction. Defaults to tf.dtypes.float32.

• name – A name for this ConvexFunction.

Initialize this ConvexFunction.
