Hierarchical probabilistic synthesis and analysis models have recently been suggested as architectures for performing density estimation. Strict hierarchies makes it easy to evaluate generative or synthetic probabilities. However, both theoretical and neurobiological considerations weigh in favour of integrating lateral influences within a layer together with top-down and bottom up influences from lower and higher layers. This is known to be computationally tricky. We suggest a new recurrent sampling model and show that has the appropriate structure and behaviour for the analysis model for linear and Gaussian factor analysis. Then we extend this model to the case of binary stochastic units. Finally, we comment on the more general use of this model.
