本项目是对《Neural Networks from Scratch in Python》读后的总结，在本项目中将应用Python（numpy）从0开始实现一个全连接神经网络，提供所有可运行代码，并对每一段代码加入注释（自己的理解）。本项目内容包括：全连接层、激活函数、损失函数、梯度、反向传播、优化器、正则化、dropout、数据集处理、模型验证、参数保存和下载、预测推理。

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.

Pushes, PRs, issues, reviews and comments — stars and forks excluded, so this is contribution rather than popularity

No issue or PR events — this repo's activity is pushes only.
Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 55 stars here means stars gained during the window, not the repo's star count.
