基于免疫匹配追踪的语音稀疏分解算法
Speech Sparse Decomposition Algorithm Based on Immune Matching Pursuit
摘要
Abstract
Aiming at the problem that since the standard Matching Pursuit(MP) algorithm tends to cause enormous calculation quantity when searching for the optimal atoms, this paper proposes a scheme of Matching Pursuit algorithm based on Immune Algorithm(IA-MP). This algorithm adopts immune cloning optimization mechanism to search for the optimal atoms, using the population scale of antibodies to control the size of redundant dictionary, and choosing real cross and nonsymmetrical mutation to ensure the completeness of dictionary. Simulation results show that, compared with the standard MP and Genetic Algorithm-Matching Pursuit(GA-MP) algorithms, IA-MP algorithms can obviously reduce the matching pursuit calculation quantity, and the performance of this algorithm is more stable, in addition, this algorithm has high signal reconstruction accuracy.关键词
