针对面向大科学数据传输网络测量中遇到的问题,为了更有效地测量与分析网络性能,提出一种基于云服务模式的网络测量与分析架构———CS-Measure(network measurement and analysis architecture of cloudservice),实现了网络测量共享式服务,降低了单个应用系统的测量负担,并进行了部署及应用。
In order to recognize people's annoyance emotions in the working environment and evaluate emotional well- being, emotional speech in a work environment is induced to obtain adequate samples of emotional speech, and a Mandarin database with two thousands samples is built. In searching for annoyance-type emotion features, the prosodic feature and the voice quality feature parameters of the emotional statements are extracted first. Then an improved back propagation (BP) neural network based on the shuffled frog leaping algorithm (SFLA) is proposed to recognize the emotion. The recognition capability of the BP, radical basis function (RBF) and the SFLA neural networks are compared experimentally. The results show that the recognition ratio of the SFLA neural network is 4. 7% better than that of the BP neural network and 4. 3% better than that of the RBF neural network. The experimental results demonstrate that the random initial data trained by the SFLA can optimize the connection weights and thresholds of the neural network, speed up the convergence and improve the recognition rate.
