WebThe model The Bayesian GP-LVM (Titsias and Lawrence, 2010) is an extension of the traditional GP-LVM where the latent space is approximately marginalised out in a … WebWhen the graph is directed and acyclic, the graphical model is called a Bayesian network (BN). To interpret BN causally, we make the common causal Markov assumption, namely, a variable is independent of its non-effects given all of its direct causes. For instance, if one believes smoking causes lung cancer only through lung tissue damage (i.e ...
