Computational complexity of queries based on itemsets
We investigate determining the exact bounds of the frequencies of conjunctions based on frequent sets. Our scenario is an important special case of some general probabilistic logi...

A general computation rule for lossy summaries/messages with examples from equalization
Abstract-- Elaborating on prior work by Minka, we formulate a general computation rule for lossy messages. An important special case (with many applications in communications) is t...

Speeeding Up Markov Chain Monte Carlo Algorithms
We prove an upper bound on the convergence rate of Markov Chain Monte Carlo (MCMC) algorithms for the important special case when the state space can be aggregated into a smaller ...

Choice in Dynamic Linking
We introduce a computational interpretation for Hilbert’s choice operator (ε). This interpretation yields a typed foundation for dynamic linking in software systems. The use of ...

Fast Algorithms for Logconcave Functions: Sampling, Rounding, Integration and Optimization
We prove that the hit-and-run random walk is rapidly mixing for an arbitrary logconcave distribution starting from any point in the support. This extends the work of [26], where t...
