ComputesY = g(X) = 1 - exp((-X / scale) ** concentration) where X >= 0
This bijector maps inputs from [0, inf] to [0, 1]. The inverse of the
bijector applied to a uniform random variable X ~ U(0, 1) gives back a
random variable with the Weibull distribution:
tfb_weibull( scale = 1, concentration = 1, validate_args = FALSE, name = "weibull" )
scale |
Positive Float-type Tensor that is the same dtype and is
broadcastable with concentration.
This is l in |
concentration |
Positive Float-type Tensor that is the same dtype and is
broadcastable with scale.
This is k in |
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. |
Y ~ Weibull(scale, concentration)
pdf(y; scale, concentration, y >= 0) = (concentration / scale) * (y / scale)**(concentration - 1) * exp(-(y / scale)**concentration)
a bijector instance.
