Handling of many-objective problems is a hot issue in the evolutionary multiobjective optimization (EMO) community. It is well-known that frequently-used EMO algorithms such as NSGA-II and SPEA do not work well on many-objective problems whereas they have been successfully applied to a large number of test problems and real-world application tasks with two or three objectives. The main difficulty...
In this paper we develop a voice activity detection algorithm based on spectrum estimation of speech and non-speech segments using vector quantization method. In this method, we try to classify entry speech signal to speech and non-speech classes. Commonly, the performance of the voice activity detection (VAD) algorithms in non-stationary background noise is not so satisfying under low SNR, so we...
In this paper we show that e-business and strategic management problems in Digital Information Management (DIM) methodologies can be efficiently solved by using corresponding adaptive algorithmic procedures. A case study representing characteristic e-business problems and strategic management methodologies in DIM related to supply chain management and automatic detection of out-of-shelf (OOS) products,...
The objective of this paper is to introduce the Improved-Ant Colony Optimization in Virtual Circuit Networks. We discuss AntNet, an improved version of Ant Colony applied as a routing protocol. A new model is proposed that introduces the application of Ant Colony Optimization in the area of communication network. The proposed model is analyzed with the application of shortest path algorithm in Virtual...
