in which K denotes a number of geometric shape components needed to represent all sources, Bk(l) is a relative amplitude for each shape component k, zk(l) is a vector that denotes latent input for the generator to produce shape component k of type l, and output of G(zk(l),l) is reshaped as a vector to match the dimension of S(ω0).
