A Comparative Study of Variable Elimination and Arc Reversal in Bayesian Network Inference
Cory J. Butz, Junying Chen, K. Konkel, Pawan J. Lingras · 2009
We compare two approaches to Bayesian network inference, called variable elimination (VE) and arc reversal (AR). It is established that VE never requires more space than AR, and never requires more computation (multiplications and additions) than AR.
