getZ: Calculate the current Z estimate responsibilities (posterior probabilities)
Description
Calculate the current Z estimate responsibilities (posterior probabilities)
Usage
getZ(z, zUsed, stillActive, nll, nllUSED)
Arguments
z
Matrix (m x n) of estimate responsibilities (probabilities that a
count comes from a spike distribution at 0).
zUsed
Matrix (m x n) of estimate responsibilities (probabilities that
a count comes from a spike distribution at 0) that are actually used
(following convergence).
stillActive
A vector of size M booleans saying if a feature is still
active or not.
nll
Vector of size M with the current negative log-likelihoods.
nllUSED
Vector of size M with the converged negative log-likelihoods.
