To enable meaning based search, computers have to store and compare meaning of user's search intentions and objects being searched. To address the key requirement of meaning compositionality, we present: design rationale; an algebraic theory; and a technique to represent composite meaning as a tensor which is amenable to efficient similarity computation.
Specialized search engines have potential to provide superior search precision, relevance and recall. A specialized P2P overlay network called semantic routed network, which forwards search queries based on their meanings, can unify a large number of specialized search engines under a single Internet wide search service. Providing fast and successful routing of search queries is a challenging task...
One of the major driving forces of bacterial foraging optimization algorithm (BFOA) is the reproduction phenomenon of virtual bacteria each of which models one trial solution of the optimization problem. During reproduction, the least healthier bacteria (with a lower accumulated value of the objective function in one chemotactic lifetime) die and the other healthier bacteria each split into two, which...
Differential evolution (DE) is well known as a simple and efficient algorithm for global optimization over continuous spaces. This article provides a simple mathematical model of the underlying evolutionary dynamics of a one-dimensional DE. The model relates the search process of DE with the classical gradient descent search and also analyzes the convergence behavior of a DE population, very near...
