In this paper we propose a new segment-synchronous speaker clustering algorithm based on the Bayesian Information Criterion (BIC), which is motivated by the Dynamic Programming (DP) idea. Compared with the commonly used agglomerative speaker clustering methods, the proposed algorithm is faster for lack of distance-matrix building and more reasonable as it avoids in some degree the simple irrevo...

We proposed earlier an optimization approach to reactive ow control where the objective of the control is to maximize the total utility of all sources over their transmission rates. The control mechanism is derived as a gradient projection algorithm to solve the dual problem. In this paper we extend the algorithm to a scaled gradient projection. The diagonal scaling matrix approximates the diag...

this paper presents a biogeography-based optimization (bbo) algorithm to solve the economic loaddispatch (eld) problem with generator constraints in thermal plants. the applied method can solvethe eld problem with constraints like transmission losses, ramp rate limits, and prohibited operatingzones. biogeography is the science of the geographical distribution of biological species. the modelsof...

This paper describes an Active Character Recognition methodology, henceforth referred to as ACR. We present in this paper a method that uses an active heuristic function similar to the one used by A* search algorithm that adaptively determines the length of the feature vector as well as the features themselves used to classify an input pattern. ACR adapts to factors such as the quality of the i...
