22 isItStillActivegetZCalculate the current Z estimate responsibilities (posterior probabilities)DescriptionCalculate the current Z estimate responsibilities (posterior probabilities)UsagegetZ(z, zUsed, stillActive, nll, nllUSED)ArgumentszzUsedstillActivenllnllUSEDMatrix (m x n) of estimate responsibilities (probabilities that a count comes froma spike distribution at 0).Matrix (m x n) of estimate responsibilities (probabilities that a count comes froma spike distribution at 0) that are actually used (following convergence).A vector of size M booleans saying if a feature is still active or not.Vector of size M with the current negative log-likelihoods.Vector of size M with the converged negative log-likelihoods.ValueA list of updated zUsed and nllUSED.See AlsofitZigisItStillActiveFunction to determine if a feature is still active.DescriptionIn the Expectation Maximization routine features posterior probabilities routinely converge basedon a tolerance threshold. This function checks whether or not the feature’s negative log-likelihood(measure of the fit) has changed or not.UsageisItStillActive(eps, tol, stillActive, stillActiveNLL, nll)
