Approximability of Probability Distributions

  title={Approximability of Probability Distributions},
  author={Alina Beygelzimer and Irina Rish},
We consider the question of how well a given distribution can be approximated with probabilistic graphical models. We introduce a new parameter,effective treewidth, that captures the degree of approximability as a tradeoff between the accuracy and the complexity of approx imation. We present a simple approach to analyzing achievable tradeo ffs that exploits the threshold behavior of monotone graph properties , and provide experimental results that support the approach.
