LibMF在矩阵分解的并行化方面作出了很好的贡献，针对SGD（随即梯度下降）优化方法在并行计算中存在的locking problem和memory discontinuity问题，提出了一种 矩阵分解的高效算法FPSGD（Fast Parallel SGD），根据计算节点的个数来划分评分矩阵block，并分配计算节点。LibSVM， Liblinear等都是他们开发的。

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

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 9 stars here means stars gained during the window, not the repo's star count.
