在机器学习的世界里，有一个函数几乎无处不在： Softmax。它将神经网络最后一层的打分变成一组概率，让模型能用“我有多确定”来回答问题。乍看，这只是一个便利的数学小工具；然而当我们把目光移向 19 世纪的统计力学，再回到 20 世纪的信息论，再 ...

For example, the MNIST data is discussed as part of the MNIST for Beginners tutorial along with the Softmax model. The follow-on tutorial “for experts” covers some of the same material again, faster, ...

Machine learning couldn’t be hotter, with several heavy hitters offering platforms aimed at seasoned data scientists and newcomers interested in working with neural networks. Among the more popular ...
