tf.contrib.distributions.softplus_inverse(x, name=None)

tf.contrib.distributions.softplus_inverse(x, name=None)

See the guide: Statistical Distributions (contrib) > Utilities

Computes the inverse softplus, i.e., x = softplus_inverse(softplus(x)).

Mathematically this op is equivalent to:

softplus_inverse = log(exp(x) - 1.)

Args:

• x: Tensor. Non-negative (not enforced), floating-point.
• name: A name for the operation (optional).

Returns:

Tensor. Has the same type/shape as input x.
