vi_total_variation: The Total Variation Csiszar-function in log-space
In rstudio/tfprobability: Interface to 'TensorFlow Probability'
vi_total_variation R Documentation
The Total Variation Csiszar-function in log-space
Description
A Csiszar-function is a member of F = { f:R_+ to R : f convex }.
Usage
vi_total_variation(logu, name = NULL)
Arguments
logu
float-like Tensor representing log(u) from above.
name
name prefixed to Ops created by this function.
Details
The Total-Variation Csiszar-function is:
f(u) = 0.5 |u - 1|
Warning: this function makes non-log-space calculations and may therefore be
numerically unstable for |logu| >> 0.
Value
total_variation_of_u: float-like Tensor of the Csiszar-function
evaluated at u = exp(logu).
