本源码通过声音传通数据，将数据调制二进制PSK(即BPSK)信号从喇叭发出来，另外一个接收程序接收到声音后，便可以解码出来，用到的技术有PSK编码、PSK解码、Windows录音，为了防止传输过程中出现的误，本原码采用rss纠错码，使得通讯更加稳定可靠。(The Source by voice through the data, binary modulation PSK (ie, BPSK) signals emitted the speaker, the other receiving program after receiving the sound, you can decode it, the techniques used have PSK encoding, PSK decoding, Windows Recording in order to prevent accidental transmission occurs, the primitive code using rss error correction code, making communications more reliable.)

梯度下降法是最早最简单，也是最为常用的最优化方法。梯度下降法实现简单，当目标函数是凸函数时，梯度下降法的解是全局解。一般情况下，其解不保证是全局最优解，梯度下降法的速度也未必是最快的。梯度下降法的优化思想是用当前位置负梯度方向作为搜索方向，因为该方向为当前位置的最快下降方向，所以也被称为是”最速下降法“。最速下降法越接近目标值，步长越小，前进越慢。(The gradient descent method is the earliest and most simple and most commonly used optimization method. The gradient descent method is simple to realize. When the objective function is a convex function, the solution of the gradient descent method is a global solution. In general, the solution is not guaranteed to be the global optimal solution, and the gradient descent method is not necessarily the fastest. The optimization idea of gradient descent method is to use the current position negative gradient direction as the search direction, because the direction is the fastest descending direction of the current position, so it is also called the steepest descent method. The faster the slowest descent approach is closer to the target, the smaller the step, the slower the progress.)
