3Blue1Brown 深度学习系列开篇之作。借助手写数字识别案例与标志性动效，深入浅出地拆解神经元、网络层及基础神经网络背后的数学原理。
为什么 HN 推它
HN 社区推荐入门神经网络的标准第一站，最受称赞的是把晦涩数学讲得极具几何直觉。
「数学概念的拆解和动效可视化简直令人叹为观止。」HN 网友原话：the visualisations and explanations of the math/concepts are so amazing
英文原摘要（HackerTube / Claude 整理）
3Blue1Brown's first chapter on deep learning explains what neurons and layers are and the math underlying a basic neural network, using handwritten digit recognition with visual animations.
HN treats it as the standard first stop for learning neural networks, praised for making the math intuitive.
HN 上的提及
3blue1brown is currently doing a terrific series on how neural networks work
here are the first few videos of the series
explains math in very accessible way
the visualisations and explanations of the math/concepts are so amazing
the sigmoid function isn't really that used anymore
