Gaia DR3

ESA Gaia Data Release 3 variable star catalog. 50K-source subset with top-1% IsolationForest on 22-dimensional variability features. Cross-validation stability (41%) indicates the selection is training-sample-conditioned; treat as exploratory, not catalog-grade.

Gaia

Exploratory tier. Cross-validation stability only 41% (training-sample-conditioned selection). 10x expansion to 500K run internally for CV diagnostics; published catalog uses original 50K scope. Dedicated Gaia-optimized detector needed.
