Exposure-Resilient Extractors and the Derandomization of Probabilistic Sublinear Time
There exists a positive constant < 1 such that for any function T(n) n and for any problem L BPTIME(T(n)), there exists a deterministic algorithm running in poly(T(n)) time w...

The Strength of Multilinear Proofs
We introduce an algebraic proof system that manipulates multilinear arithmetic formulas. We show that this proof system is fairly strong, even when restricted to multilinear arith...

Communication Complexity Under Product and Nonproduct Distributions
We solve an open problem in communication complexity posed by Kushilevitz and Nisan (1997). Let R (f) and D

Automatic Grammar Partitioning for Syntactic Parsing
Natural language processing technologies offer ease-of-use of computers for average users, and easeof-access to on-line information. Natural language, however, is complex, and the...

Parsing and Hypergraphs
While symbolic parsers can be viewed as deduction systems, this view is less natural for probabilistic parsers. We present a view of parsing as directed hypergraph analysis which ...
