mfcc
- matlab下语音处理,求mfcc参数,需要voicebox工具箱-matlab for speech processing, seeking mfcc parameters need voicebox toolbox
Single-exponential-smoothing
- 一次指数平滑法是指以最后的一个第一次指数平滑。如果为了使指数平滑值敏感地反映最新观察值的变化,应取较大阿尔法值,如果所求指数平滑值是用来代表该时间序列的长期趋势值,则应取较小阿尔法值。同时,对于市场预测来说,还应根据中长期趋势变动和季节性变动情况的不同而取不同的阿尔法值,一般来说,应按以下情况处理:1.如果观察值的长期趋势变动接近稳定的常数,应取居中α值(一般取0.6—0.4)使观察值在指数平滑中具有大小接近的权数;2.如果观察值呈现明显的季节性变动时,则宜取较大的α值(一般取0.6一0.9),
