Roadmap

Completed v2 direction

• Composable FeatureMap and Solver architecture.
• Batch ridge solve with tunable regularization.
• Online RLS with ReOS-ELM, FOS-ELM, and OS-CELM toggles.
• Real RBF feature maps.
• Learned ELM-AE feature extraction, ML-ELM, and H-OS-ELM.
• CUDA primitive layer for shared GPU operations.
• Dataset IO, preprocessing, and drift streams.
• Narrative documentation suite.

Remaining work

Step	Work
U11	MkDocs Material site, Doxygen API reference, strict docs build
U12	README badges, generated benchmark table, demo assets
U13	GitHub Actions CI, GHCR publishing, versioned releases

Future ideas

• Optional Python bindings after a spec update.
• More datasets and larger benchmark snapshots.
• Self-hosted GPU CI for CUDA runtime tests.
• Model export format for demo reproducibility.
• More detailed drift-stream scenarios beyond the bundled synthetic stream.
