Computing Upper and Lower Bounds on Likelihoods in Intractable Networks
Tommi Jaakkola, Michael I. Jordan · arXiv (Cornell University) · 2013
We present deterministic techniques for computing upper and lower bounds on marginal probabilities in sigmoid and noisy-OR networks. These techniques become useful when the size of the network (or clique size) precludes exact computations. We illustrate the tightness of the bounds by numerical experiments.
