神经网络的 语音识别 初学者可以看看 希望对大家有帮助(Speech recognition neural network can look at beginners)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)

用Bessel方程展开计算有限电流源向外辐射的电场和磁场，输出较全的电磁学参数。(Computation of Bessel equation with limited current source radiating electric and magnetic fields, output over the entire electromagnetic parameters.)

梯度下降法在一维函数中的优化应用，自己原创，可以运行，无任何错误(Gradient descent algorithm applied in a one-dimensional function optimization, and their own original, can run without error.)

An example case is considered to price an option at a maturity of T years - prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity. Finally option prices are compared to Black Scholes values to verify results(An example case is considered to price an option at a maturity of T years- prices are simulated for Geometric brownian motion process at 2*T maturity, and Brownian Bridge is used to obtain prices at T maturity.

first, this project simulates cdma network using 63 gold code over Rayleigh fading channel.then ,compares rake receiver performance with ordinary receiver and theory awgn and theory Rayleigh channel . finally , we observe decreasing ber when number of users is increasable.

采用hog+SVM对路标进行识别，先训练再测试，准确率达到百分之九十四左右。(Hog +SVM is adopted to identify road signs, which is trained first and then tested, with an accuracy rate of about 94 percent.)
