From the joint p(m, z|θ), again using rules from (Petersen et al., 2008) Sections (8.1.2) we get For the case of two views, the joint probability can be factored as where  This follows the same form as regular factor analysis, but with a block-diagonal constraint on Ψ.
by Equations (5) and (6) of (Ghahramani et al., 1996), we apply EM as follows.
