When electrical current stimuli of predetermined frequency and amplitudes are applied on a subject, an amplifier is employed to monitor the subject's galvanic skin response (GSR).

当向被试施加特定频率、幅度的电流刺激时，被试的皮肤电流响应信号由一个放大仪客观地记录下来。

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).

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。
