Geometric SVM: A Fast and Intuitive SVM Algorithm
We present a geometrically motivated algorithm for finding the Support Vectors of a given set of points. This algorithm is reminiscent of the DirectSVM algorithm, in the way it picks data points for inclusion in the Support Vector set, but it uses an optimization based approach to add them to the Support Vector set. This ensures that the algorithm scales to O(n) in the worst case and O(n|S|) in...
متن کاملFast Bayesian Shape Matching Using Geometric Algorithms
We present a Bayesian approach to comparison of geometric shapes with applications to classification of the molecular structures of proteins. Our approach involves the use of distributions defined on transformation invariant shape spaces and the specification of prior distributions on bipartite matchings. Here we emphasize the computational aspects of posterior inference arising from such model...
متن کاملGeometric constant defining shape transitions of carbon nanotubes under pressure.
We demonstrate that when a single-walled carbon nanotube is under pressure it undergoes a series of shape transitions, first transforming from a circle to an oval and then from an oval to a peanut. Most remarkably, the ratio of the area of the tube cross sections at the second transition over that at the first transition appears as a constant, independent of the tube radius. Its accurate value ...
متن کاملSocial heuristics shape intuitive cooperation.
Cooperation is central to human societies. Yet relatively little is known about the cognitive underpinnings of cooperative decision making. Does cooperation require deliberate self-restraint? Or is spontaneous prosociality reined in by calculating self-interest? Here we present a theory of why (and for whom) intuition favors cooperation: cooperation is typically advantageous in everyday life, l...
متن کاملFast and Intuitive Clustering of Web Documents
Conventional document retrieval systems (e.g., Alta Vista) return long lists of ranked documents in response to user queries. Recently, document clustering has been put forth as an alternative method of organizing the results of a retrieval 6]. A person browsing the clusters can discover patterns that would be overlooked in the traditional ranked-list presentation. In this context, a document c...
