ComputesY = g(X) = exp(-exp(-(X - loc) / scale))
Description
This bijector maps inputs from [-inf, 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 Gumbel distribution:
Usage
tfb_gumbel(loc = 0, scale = 1, validate_args = FALSE, name = "gumbel")
Arguments
loc |
Float-like Tensor that is the same dtype and is broadcastable with scale.
This is loc in |
scale |
Positive Float-like Tensor that is the same dtype and is broadcastable with loc.
This is scale 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. |
Details
Y ~ Gumbel(loc, scale)
pdf(y; loc, scale) = exp(-( (y - loc) / scale + exp(- (y - loc) / scale) ) ) / scale
Value
a bijector instance.
