Fast nonlinear manifold learning preserving local and global structure. Standard UMAP (fit/transform, sklearn-compatible), supervised/semi-supervised, Parametric UMAP (NN encoder/decoder, TensorFlow), DensMAP (density), AlignedUMAP (temporal/batch). 15+ distance metrics, custom Numba metrics, precomputed distances. For linear reduction use PCA; for neighborhood graphs use sklearn NearestNeighbors.","version":1,"lift":{"pass_rate_delta_pts":13.04,"pass_rate_pct":95.7,"total_cases":23,"passed_cases":22,"tokens_delta_pct":304.6,"turns_delta_pct":0,"verdict":"mixed","benchmark_model":"gemini-3.6-flash","grading_method":"judged","completed_at":"2026-08-23T23:31:30.433746+00:00"},"skill_score":0.9565,"benchmark_models":[{"model":"gemini-3.6-flash","headline":true,"delta_pts":13.04,"with_pass_pct":95.7,"without_pass_pct":82.6,"tokens_delta_pct":304.6,"turns_delta_pct":0,"total_cases":23,"cases_aggregated":23,"verdict":"mixed","never_hurt":true,"completed_at":"2026-08-23T23:31:30.433746+00:00","run_id":"bde21f27-5cab-4015-92d7-c7fc5523be1e","version_number":1,"is_latest_version":true,"gate":null}],"trust":{"skill_safety":"passed","safety_status":"clean","intent_verdict":"safe","content_status":"clean","indexable":true},"license":"BSD-3-Clause","install_count":0,"manifest_hash":"344e228c13744c0bf75869139124358efc964adc2d37cbdde2dc1f79a47c480a","raw_url":"https://app.decimal.ai/s/jaechang-hits-umap-learn/SKILL.md","scorecard_url":"https://app.decimal.ai/skills/jaechang-hits-umap-learn"}
