It is necessary to study the application of digital technology in English speech feature recognition. This paper combines actual needs recognition improve algorithm. Moreover, this fuzzy algorithm analyze features, analyzes shortcomings traditional algorithms, proposes digitized algorithm, and builds an model on basis. In addition, conducts time-frequency analysis chaotic signals signals, elimi...

Web page intelligent parsing is an inevitable part of data collection. News web pages contain a lot information with little relevance to the topic, which makes it difficult locate text content directly and quickly during collection process. This paper proposes algorithm based on symbol density. Through empirical research mainstream news websites in China, can accurately extract pages.

We are doing research and development of an intelligent lighting system. In the intelligent lighting system, the algorithm which controls lighting fixtures is important. In this research, we examine how to grasp the position relation between the lighting and the illuminance sensors with sufficient accuracy, and we propose a lighting control algorithm which estimates accurate position relation b...

As the fourth fundamental circuit element, memristor may execute computations while storing data. Fracmemristor takes advantage of fractional calculate’s long-term memory, non-locality, weak singularity, and memristor’s storage–computational integration. Since physical structure fracmemristor is similar to topology ant transfer probability flow in ACO, we propose fractional-order memristive col...

In order to solve the portfolio problem when security returns are bifuzzy variables, firstly we propose a new definition of risk, then one type of portfolio selection based on expected value and risk is provided according to bifuzzy theory. Furthermore, a hybrid intelligent algorithm by integrating bifuzzy simulation and genetic algorithm is designed. Finally, one numerical experiment is provid...
