Deep Manifold

Through the lens of manifold covers, we open a mathematical window into neural networks. At its core lies something unexpectedly simple: inequality, integration, and differentiation.

深度流形的数学展望

English Edition: The Mathematical Outlook of Deep Manifold

微分方程可能是描述真实世界最重要的一类方程。数学上研究微分方程,有代数,也有几何。相比代数,几何对空间、变化、局部与整体的描述更有广度、深度和变化性。陈省身把现代微分几何推进到新的高度;丘成桐为了证明卡拉比猜想,发展了几何上的非线性微分方程,也就是后来所谓的几何分析,把微分几何进一步推进到非线性世界。但陈和丘都没有讲如果解“微分方程“, 微分方程没有解, 就...

当数学之美在 AI 中变得有用

English Edition: When Mathematical Beauty Becomes Useful in AI

数学的无用美和方程的解

有人把数学称为“无用的美”,这句话有它的道理。现实世界纷繁复杂、瑰丽多姿,既有结构,也有变化。江泽涵, 石根华老师的老师, 在上世纪五十年代末曾讲过一句很有意思的话:“通过微分方程的窗子,数学家看到现实世界的光。”这句话点出了一个很深的问题:如果我们希望用数学描述一个不断变化的真实世界,微分方程可能是最重要的语言之...

LLM 情绪的讨论,错过了真正的问题

English Edition: Why LLM Emotion Talk Misses the Real Question

Anthropic 关于 Claude 情绪概念的文章,是一个很好的例子:它一方面显示了 LLM 研究已经推进到什么程度,另一方面也说明公众讨论是如何很容易偏离方向的。文章认为,模型内部可以存在对情绪概念的表征,而且这些表征会在功能上影响行为;但同时,它也明确没有声称模型具有主观感受,或具有人类式的内在体验。这一区分很重要。然而,一旦“恐惧”“绝望”...
