Learning Human Interactions with the Influence Model
 MIT MEDIA LABORATORY TECHNICAL NOTE
, 2001
"... We are interested in quantitatively modeling the interactions between humans in conversational settings. While a variety of models are potentially appropriate, such as the coupled HMM, all require a very large number of parameters to describe the interactions between chains. We propose as an alt ..."

as an alternative the generative model developed in [1], the Influence Model, which parametrizes the hidden state transition probabilities by taking a convex combination of the pairwise transitions with constant "influence" parameters. We develop a learning algorithm for this model and show its
Measuring Global Behaviour of MultiAgent Systems from PairWise Mutual Information
"... Abstract. In this paper we present a method for finding general dependencies between individual agents in a multiagent system. We use mutual information as the general measure for dependence and demonstrate how it can be used to estimate pairwise coupling in a 2 dimensional swarm. We then show tha ..."

Pairwise Coupled Hybrid Vanadium DioxideMOSFET (HVFET) Oscillators for NonBoolean Associative Computing
"... Information processing applications related to associative computing like image / pattern recognition consume excessive computational resources in the Boolean processing framework. This motivates the exploration of a nonBoolean computing approach for such applications. In this work, we demonstrate, ..."

An Active Learning Algorithm for Ranking from Pairwise Preferences with an Almost Optimal Query Complexity
"... Given a set V of n elements we wish to linearly order them given pairwise preference labels which may be nontransitive (due to irrationality or arbitrary noise). The goal is to linearly order the elements while disagreeing with as few pairwise preference labels as possible. Our performance is measu ..."

Neighborliness of RandomlyProjected Simplices in High Dimensions
 Proc. Natl. Acad. Sci. USA
, 2005
"... Let A be a d by n matrix, d < n. Let T = T n−1 be the standard regular simplex in R n. We count the faces of the projected simplex AT in the case where the projection is random, the dimension d is large and n and d are comparable: d ∼ δn, δ ∈ (0, 1). The projector A is chosen uniformly at random ..."

and Sporyshev, who obtained qualitative results about the existence of a threshold ρV S(δ)> 0 at which phase transition occurs in k/d. We compute and display ρV S and compare to ρN. Our results imply that the convex hull of n Gaussian samples in R d, with n large and proportional to d, ‘looks like a simplex
THE PHASE TRANSITION FOR DYADIC TILINGS
"... Abstract. Adyadictile ofordernis anyrectangleobtained from the unit square by n successive bisections by horizontal or vertical cuts. Let eachdyadictile ofordernbe availablewith probabilityp, independently of the others. We prove that for p sufficiently close to 1, there exists a set of pairwise dis ..."

Reduced Rank Approximations of Transition Matrices
 AI & STATS
, 2003
"... We present various latent variable models for the reduced rank approximation of transition matrices. Two main categories of models, termed Latent Markov Analysis(LMA) models, are introduced. We first address the case where the transition matrix is consistent with a reversible random walk. A more gen ..."

Transitive Comparison of Marginal Probability Distributions
"... A generalized dice model for the pairwise comparison of nonnecessarily independent random variables is established. It is shown how the transitivity of the probabilistic relation generated by the model depends on the copula defining the coupling of the marginal distribution functions in the joint d ..."
