Boolean Factor Analysis (BFA) implies that signal components, factor loadings and factor scores are binary variables. In this study new approach to Boolean factor analysis (BFA) based on combining previously offered BFA method ANNIA (Attractor Neural Network with Increasing Activity) and likelihood maximization is described. We demonstrate the efficiency of new method when analyzing the KEGG database containing full genome sequencing of 1368 organisms.
