  交叉熵

一个非常常见的,非常漂亮的成本函数是“交叉熵”(cross-entropy)。交叉熵产生于信息论里面的信息压缩编码技术,但是它后来演变成为从博弈论到机器学习等其他领域里的重要技术手段。

Cross entropy

  • abstract: In information theory, the cross entropy between two probability distributions measures the average number of bits needed to identify an event from a set of possibilities, if a coding scheme is used based on a given probability distribution q, rather than the "true" distribution p.
