CLUSTER SYNERGY MENTAL MAP

Measurement and the mental map

In order to test between subtractive and ratio theories of stimulus comparison, judges were asked to estimate "ratios" and "differences" of easterliness and westerliness of U.S. cities. "Difference" judgments fit the subtractive model, and "ratio" judgments fit the ratio model. However, "ratios" and "differences" were monotonically related, contrary to the theory that judges compute both relati...

Lifting Relational MAP-LPs using Cluster Signatures

Inference in large scale graphical models is an important task in many domains, and in particular probabilistic relational models (e.g. Markov logic networks). Such models often exhibit considerable symmetry, and it is a challenge to devise algorithms that exploit this symmetry to speed up inference. Recently, the automorphism group has been proposed to formalize mathematically what ”exploiting...

Coupled Map Lattices without Cluster Expansion

We present an approach to the investigation of the statistical properties of weakly coupled map lattices that avoids completely cluster expansion techniques. Although here it is implemented on a simple case we expect similar strategies to be applicable in a much larger class of situations.

Parallel Processing of cluster by Map Reduce

MapReduce is a parallel programming model and an associated implementation introduced by Google. In the programming model, a user specifies the computation by two functions, Map and Reduce. The underlying MapReduce library automatically parallelizes the computation, and handles complicated issues like data distribution, load balancing and fault tolerance. Massive input, spread across many machi...
