Efficient Computationally Private Information Retrieval from Anonymity or Trapdoor Groups
A Private Information Retrieval (PIR) protocol allows a database user, or client, to obtain information from a data- base in a manner that prevents the database from knowing which...

Efficient Lifting for Online Probabilistic Inference
Lifting can greatly reduce the cost of inference on firstorder probabilistic graphical models, but constructing the lifted network can itself be quite costly. In online applicatio...

Near-Optimal Conversion of Hardness into Pseudo-Randomness
Various efforts ([?, ?, ?]) have been made in recent years to derandomize probabilistic algorithms using the complexity theoretic assumption that there exists a problem in E = dti...
