tfb_scale_matvec_lu

Matrix-vector multiply using LU decomposition.

Description

This bijector is identical to the "Convolution1x1" used in Glow (Kingma and Dhariwal, 2018).

Usage

tfb_scale_matvec_lu(
  lower_upper,
  permutation,
  validate_args = FALSE,
  name = NULL
)

Arguments

`lower_upper`	The LU factorization as returned by `tf$linalg$lu`.
`permutation`	The LU factorization permutation as returned by `tf$linalg$lu`.
`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.
