Generally, the maximum value representable by an unsigned word will be sys.maxsize * 2 + 1, and the number of bits in a word will be math.log2(sys.maxsize * 2 + 2). See this answer for more information. Python 2 In Python 2, the maximum value for plain int values is available ...

在这篇博文中,我们将探讨如何通过Python实现mRMR算法(Minimum Redundancy Maximum Relevance),该算法常用于特征选择,尤其在高维数据分析中。以下是解决这一问题的具体过程。 ### 背景描述 在当今的数据科学和机器学习领域,特征选择是一个至关重要的步骤。mRMR算法通过最小化特征之间的冗余度和最大化特征与目标变量的相...
