The mixture structure allows a subject to express several templates in different proportions rather than belong to one hard cluster. BALM becomes more advantageous as memberships overlap, but is less advantaged when the truth is nearly categorical. Each subject's latent edge-strength vector is represented as a convex combination of shared templates. Subject weights lie on a simplex and sum to one across templates.
