tfd_uniform

Uniform distribution with low and high parameters

Description

Mathematical Details

Usage

tfd_uniform(
  low = 0,
  high = 1,
  validate_args = FALSE,
  allow_nan_stats = TRUE,
  name = "Uniform"
)

Arguments

`low`	Floating point tensor, lower boundary of the output interval. Must have `low < high`.
`high`	Floating point tensor, upper boundary of the output interval. Must have `low < high`.
`validate_args`	Logical, default FALSE. When TRUE distribution parameters are checked for validity despite possibly degrading runtime performance. When FALSE invalid inputs may silently render incorrect outputs. Default value: FALSE.
`allow_nan_stats`	Logical, default TRUE. When TRUE, statistics (e.g., mean, mode, variance) use the value NaN to indicate the result is undefined. When FALSE, an exception is raised if one or more of the statistic's batch members are undefined.
`name`	name prefixed to Ops created by this class.

Details

The probability density function (pdf) is,

pdf(x; a, b) = I[a <= x < b] / Z
Z = b - a

where

low = a,
high = b,
Z is the normalizing constant, and
I[predicate] is the indicator function for predicate.

The parameters low and high must be shaped in a way that supports broadcasting (e.g., high - low is a valid operation).

Value

a distribution instance.
