Python 3.8 random.choice在从文件生成的列表中进行选择时未按预期工作这是python中的一个常见问题。当你使用string.split(chars)时，python会用这些字符来拆分字符串，即使分隔符后面什么也没有。所以，举个例子，你的“intro.txt”会产生这个列表-['Hi.', 'Hello.', 'Yo.', 'What up?',
You’ve probably seen random.seed(999), random.seed(1234), or the like, in Python. This function call is seeding the underlying random number generator used by Python’s random module. It is what makes subsequent calls to generate random numbers deterministic: input A always produces output ...
whereH(⋅) is the class entropy function. The split functionh(x,θn) can be an arbitrary classifier. A common choice is a stump function that is found to be computationally efficient and effective in practice (Dollar and Zitnick, 2014). The training procedure continues to split the sample...
