Towards Tree Automata-based Success Types
Error detection facilities for dynamic languages are often based on unit testing. Thus, the advantage of rapid prototyping and flexibility must be weighed against cumbersome and time consuming test suite development. Lindahl and Sagonas’ success typings provide a means of static must-fail detection in Erlang. Due to the constraintbased nature of the approach, some errors involving nested tuples...
متن کاملNegative Tree Reweighted Belief Propagation
We introduce a new class of lower bounds on the log partition function of a Markov random field which makes use of a reversed Jensen’s inequality. In particular, our method approximates the intractable distribution using a linear combination of spanning trees with negative weights. This technique is a lower-bound counterpart to the tree-reweighted belief propagation algorithm, which uses a conv...
