Directional Histogram Model for Three-Dimensional Shape Similarity
In this paper, we propose a novel shape representation we call Directional Histogram Model (DHM). It captures the shape variation of an object and is invariant to scaling and rigi...

In-group/out-group effects in distributed teams: an experimental simulation
Modern workplaces often bring together virtual teams where some members are collocated, and some participate remotely. We are using a simulation game to study collaborations of 10...

Empirical Price Modeling for Sponsored Search
We present a characterization of empirical price data from sponsored search auctions. We show that simple models drawing bid values independently from a fixed distribution can be...

A comparison of search heuristics for empirical code optimization
—This paper describes the application of various search techniques to the problem of automatic empirical code optimization. The search process is a critical aspect of auto-tuning...
