Generalized loopy 2U: A new algorithm for approximate inference in credal networks
Credal nets generalize Bayesian nets by relaxing the requirement of precision of probabilities. Credal nets are considerably more expressive than Bayesian nets, but this makes bel...

A general approximation framework for direct optimization of information retrieval measures
Recently direct optimization of information retrieval (IR) measures becomes a new trend in learning to rank. Several methods have been proposed and the effectiveness of them has ...

Approximate Models for General Cache Networks
Abstract—Many systems employ caches to improve performance. While isolated caches have been studied in-depth, multicache systems are not well understood, especially in networks w...

Power series approximations for two-class generalized processor sharing systems
: We develop power series approximations for a discrete-time queueing system with two parallel queues and one processor. If both queues are non-empty, a customer of queue 1 is serv...
