基于核相关分析算法的情感识别模型

针对目前情感识别模型中存在的识别精度低、速度慢等问题,设计一种基于核相关分析算法的情感识别模型.首先对目前情感识别的研究现状进行分析,找出导致识别精度低的原因;然后提取情感识别的特征,并通过核相关分析算法选择最优情感识别的特征子集,减少情感识别的特征向量数;最后选择高斯混合模型对情感识别的训练集进行建模,并通过具体情感数据集进行仿真实验.实验结果表明,核相关分析算法可有效去除情感识别的不利特征,加快了情感识别速度,提高了情感识别的正确率.     

Performance Prediction of Carbon Fiber Protofilament Based on SAGA-SVR

The existing optimized performance prediction of carbon fiber protofilament process model is still unable to meet the production needs. A way of performance prediction on carbon fiber protofilament was presented based on support vector regression （SVR） which was optimized by an optimization algorithm combining simulated annealing algorithm and genetic algorithm （SAGA-SVR）. To verify the accuracy of the model, the carbon fiber protofilament production test data were analyzed and compared with BP neural network （BPNN）. The results show that SAGA-SVR can predict the performance parameters of the carbon fiber protofilament accurately.
