In the above code, we start by using the input() function to ask the user for two integers. The input() function takes a string as an argument, which is displayed to the user as a prompt. The user can then enter a value, which is returned by the input() function as a string. S...

损失函数(Loss Function)和成本函数(Cost Function)之间有什么区别? 在此强调这一点,尽管成本函数和损失函数是同义词并且可以互换使用,但它们是不同的。 损失函数用于单个训练样本。它有时也称为误差函数(error function)。另一方面,成本函数是整个训练数据集的平均损失(average function)。优化策略旨在最小化成本函数...
