| 摘 要： | 为了增强情感识别过程中皮肤电反应(GSR)信号特征选择的有效性,提出了一种改进的模拟退火免疫粒子群算法。首先,对342组被试6种情感的GSR信号进行去噪处理和原始特征提取;然后,将模拟退火机制引入到免疫粒子群(IPSO)算法的粒子更新过程中,使用新构造的模拟退火免疫粒子群(SA-IPSO)算法进行特征优化选择。实验表明:与IPSO相比,SA-IPSO能以较少特征获得较高的识别率,模拟退火机制的应用能更好地优化特征选择过程,且新的算法具有良好的全局收敛性能。

| Abstract: | An improved immune particle swarm optimization was presented in this study in order to increase the effectiveness of feature selection for emotion recognition based on Galvanic Skin Response (GSR). Firstly, 342 groups of GSR signal with each containing 6 kinds of affective data were denoised, and afterwards the original features were extracted. Then simulated annealing mechanism was introduced to the particle update process of Immune Particle Swarm Optimization (IPSO), and the Simulated Annealing-Immune Particle Swarm Optimization (SA-IPSO) was adopted for feature selection. The experimental results show that compared with IPSO, SA-IPSO can achieve relatively high recognition rate with fewer features, the application of simulated annealing mechanism can help with the optimization of feature selection, and the improved algorithm also performs well on global convergence. |
