Optimal Strategies for Bidding on Perfect Substitutes in Simultaneous Vickrey Auctions
We derive optimal bidding strategies for a global bidder who participates in multiple, simultaneous second-price auctions with perfect substitutes. We first consider a model where...

Comparison of methods for estimating the nucleotide substitution matrix
Background: The nucleotide substitution rate matrix is a key parameter of molecular evolution. Several methods for inferring this parameter have been proposed, with different math...

An interactive visualization tool to explore the biophysical properties of amino acids and their contribution to substitution ma
Background: Quantitative descriptions of amino acid similarity, expressed as probabilistic models of evolutionary interchangeability, are central to many mainstream bioinformatic ...

Learning dictionaries of stable autoregressive models for audio scene analysis
In this paper, we explore an application of basis pursuit to audio scene analysis. The goal of our work is to detect when certain sounds are present in a mixed audio signal. We fo...

A Primal-Dual Algorithm for Computing Fisher Equilibrium in the Absence of Gross Substitutability Property
Abstract. We provide the first strongly polynomial time exact combinatorial algorithm to compute Fisher equilibrium for the case when utility functions do not satisfy the Gross su...
