lmcinnes / pynndescent

A Python nearest neighbor descent for approximate nearest neighbors

PythonBSD-2-Clause★ 969 stars⑂ 105 forkssince Feb 2018View on GitHub ↗

lmcinnes/pynndescent holds a health index of 59 out of 100, placing it in the Moderate band. It scores highest on Community & Adoption (78/100) and lowest on AI Readiness (36/100). It was last updated 35 days ago. A single contributor accounts for most of its recent work.

Software health index

Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.

Score profile

Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.
