The Complexity of Approximating Bounded-Degree Boolean #CSP
The degree of a CSP instance is the maximum number of times that a variable may appear in the scope of constraints. We consider the approximate counting problem for Boolean CSPs wi...

Approximate query mapping: Accounting for translation closeness
Abstract In this paper we present a mechanism for approximately translating Boolean query constraints across heterogeneous information sources. Achieving the best translation is ch...

Privacy-preserving approximation of L1 distance for multimedia applications
Alice and Bob possess sequences x and y respectively and would like to compute the 1 distance, namely x - y 1 under privacy and communication constraints. The privacy constraint r...

Convex approximations for a class of mixed-integer recourse models
We consider mixed-integer recourse (MIR) models with a single recourse constraint. We relate the second-stage value function of such problems to the expected simple integer recour...
