ComputesY = g(X) = (1 + X * c)**(1 / c), where X >= -1 / c

The power transform maps inputs from [0, inf] to [-1/c, inf]; this is equivalent to the inverse of this bijector. This bijector is equivalent to the Exp bijector when c=0.

tfb_power_transform(power, validate_args = FALSE, name = "power_transform")

Arguments

power	float scalar indicating the transform power, i.e., Y = g(X) = (1 + X * c)**(1 / c) where c is the power.
validate_args	Logical, default FALSE. Whether to validate input with asserts. If validate_args is FALSE, and the inputs are invalid, correct behavior is not guaranteed.
name	name prefixed to Ops created by this class.

Value

a bijector instance.
