Computer programming may seem like magic these days, but most programs are built from conceptual steps that use visual aids to work out how the program needs to flow. Each function of a program can be ...

1.1 为什么需要 优化函数？ 在机器学习算法中，通常存在很多问题并没有最优的解，或是要计算出最优的解要花费很大的计算量，面对这类问题一般的做法是利用迭代的思想尽可能的逼近问题的最优解。将解决此类优化问题的方法叫做优化算法，优化算法本质上 ...
