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

tfb_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.

Details

Warning: this bijector never verifies the scale matrix (as parameterized by LU ecomposition) is invertible. Ensuring this is the case is the caller's responsibility.
