Library for factorization machines。LibFM是专门用于矩阵分解的利器，尤其是其中实现了MCMC（Markov Chain Monte Carlo）优化算法，比常见的SGD优化方法精度要高，但运算速度要慢一些。当然LibFM中还 实现了SGD、SGDA（Adaptive SGD）、ALS（Alternating Least Squares）等算法。

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.

Totals cover only the window loaded into ClickHouse and count events, not GitHub's lifetime totals — 42 stars here means stars gained during the window, not the repo's star count.
