print_every = 100 # print results interval这行代码设么意思

`print_every = 100` 这行代码是一个变量赋值，它定义了一个名为 `print_every` 的变量，并将其值设置为整数 100。在编程中，这通常用于控制程序输出结果的频率。比如，在一个循环中，每打印出 100 条数据才会显示一次当前的结果，以此来减少输出信息量，提高代码运行的效率。当你需要定期查看进展，但又不想频繁打扰程序执行的时候，这个参数就非常有用。

These are parameters used in machine learning or deep learning algorithms. Here's what they mean:

- `learning_rate`: This is a hyperparameter that determines the step size at each iteration while moving toward a minimum of a loss function. A high learning rate can cause the algorithm to converge quickly, but it may overshoot the minimum. A low learning rate can cause the algorithm to converge slowly, but it may have a better chance of finding the true minimum.

- `momentum`: This is another hyperparameter that controls the rate at which the algorithm learns from previous iterations. A high momentum value means that the algorithm will take larger steps in the direction of the previous gradient, while a low momentum value means that the algorithm will take smaller steps.

- `log_interval`: This parameter determines how often the algorithm will print out progress updates. For example, if `log_interval` is set to 10, the algorithm will print out the current loss value every 10 iterations.

- `random_seed`: This parameter is used to set a random seed for the algorithm. Setting a random seed ensures that the algorithm will produce the same results every time it is run, which is useful for reproducibility and debugging.

Overall, these parameters can have a significant impact on the performance and convergence of machine learning algorithms. It's important to experiment with different values and find the optimal combination for a given task.
