单神经元自适应PID控制的仿真研究 CHAP

说明：  matlab 编写的模拟退火算法用于求解TSP问题，里面有中国31个城市的坐标，作为例子。(matlab sa for tsp )

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)

双线性变换法设计Butterworth滤波器。分别画出滤波前和滤波后的时域图和频谱图。(Bilinear transform design Butterworth filter. Draw the pre-filter and the filtered time-domain and frequency spectrum.)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )

通过构造加博函数进行加博滤波实现对指纹图像的二值化(By constructing Gabor function Gabor filter is on the fingerprint image binarization)

动量bp算法源程序。网上找来的。希望有用。多谢支持(momentum bp algorithm source. The design of the Internet. Hope useful. Thank you for your support)

deeplearning的工具箱，里面包含了多种神经网络的模型(deeplearning toolbox, which contains a variety of neural network models)
