最速下降法
说明： 最速下降法是迭代法的一种,可以用于求解最小二乘问题(线性和非线性都可以)。在求解机器学习算法的模型参数，即无约束优化问题时，梯度下降（Gradient Descent）是最常采用的方法之一，另一种常用的方法是最小二乘法。在求解损失函数的最小值时，可以通过梯度下降法来一步步的迭代求解，得到最小化的损失函数和模型参数值。反过来，如果我们需要求解损失函数的最大值，这时就需要用梯度上升法来迭代了。在机器学习中，基于基本的梯度下降法发展了两种梯度下降方法，分别为随机梯度下降法和批量梯度下降法。(The steepest descent method is a kind of iterative method, which can be used to solve the least squares problem (both linear and nonlinear). In solving the model parameters of machine learning algorithm, that is, unconstrained optimization, gradient descent is one of the most commonly used methods, and the other is the least square method. When solving the minimum value of loss function, the gradient descent method can be used step by step to get the minimum value of loss function and model parameters. Conversely, if we need to solve the maximum value of the loss function, then we need to use the gradient rise method to iterate. In machine learning, two kinds of ladders are developed based on the basic gradient descent method)

pam
脉冲振幅（PAM）的仿真：脉冲振幅调制，即是脉冲载波的幅度随基带信号变化的一种调制方式。如果脉冲载波是由冲激脉冲组成的，则前面所说的抽样定理，就是脉冲振幅调制的原理。(Pulse amplitude (PAM) of the simulation: Pulse amplitude modulation, that is, the range of carrier pulse with changes in base-band signal of a modulation. If the pulse carrier is formed by the impulse of the pulse, then said in front of the sampling theorem, that is, the principle of pulse amplitude modulation.)
