For a specific document $n$ and feature $k$, the optimal variational parameter $\phi_nk$ (the probability that feature $k$ is active for data point $n$) is updated by solving the fixed-point equation derived from the ELBO gradient: $$ \phi_nk \propto \exp\left( E_q[\log \pi_k] + E_q[\log p(x_n | z_nk=1, \textrest)] \right) $$ Unlike batch VI, ICD computes this update and immediately updates the sufficient statistics required for the global parameters.
Periodically check that your most common ICD codes are correctly triggering the necessary safety warnings. Conclusion icd bbw fixed
