Identifying Synonyms among Distributionally Similar Words
There have been many proposals to compute similarities between words based on their distributions in contexts. However, these approaches do not distinguish between synonyms and an...

Computing the depth of a flat
We compute the regression depth of a k-flat in a set of n points in Rd, in time O(nd-2 + n log n) for 1 k d - 2. This contrasts with a bound of O(nd-1 + n log n) when k = 0 or

On Bipartite Matching under the RMS Distance
Given two sets A and B of n points each in R2 , we study the problem of computing a matching between A and B that minimizes the root mean square (rms) distance of matched pairs. W...

A Fast and Practical Algorithm for Generalized Penetration Depth Computation
— We present an efficient algorithm to compute the generalized penetration depth (PDg) between rigid models. Given two overlapping objects, our algorithm attempts to compute the...

Homotopy Methods to Compute Equilibria in Game Theory
This paper presents a complete survey of the use of homotopy methods in game theory. Homotopies allow for a robust computation of game-theoretic equilibria and their refinements....

Computing Acute and Non-obtuse Triangulations
We propose a method for computing acute (non-obtuse) triangulations. That is, for a given two dimensional domain (a set of points or a planar straight line graph), we compute a tr...

Computing Automorphic Forms on Shimura Curves over Fields with Arbitrary Class Number
We extend methods of Greenberg and the author to compute in the cohomology of a Shimura curve defined over a totally real field with arbitrary class number. Via the Jacquet-Langlan...

Fast Approximate PCPs
We investigate the question of when a prover can aid a verifier to reliably compute a function faster than if the verifier were to compute the function on its own. Our focus is ...
