duckdb-mlpack 0.0.4: Added random forest and logistic regression

Tue, 11 Nov 2025 16:01:00 CDT

A new release of the budding duckdb extension for mlpack, the C++ header-only library for machine learning, was merged into the duckdb community extensions repo today, and has been updated at its duckdb ‘mlpack’ extension page.

This release 0.0.4 adds two new methods (random forests, and regularized logistic regression), reworked the interface a little to now consistently provide fit (or train) and predict methods, adds a new internal state variable mlpack_verbose which can trigger (or suppress) verbose mode directly from SQL, expanded the documentation and added more unit tests.

For more details, see the repo for code, issues and more, and the extension page for more about this duckdb community extension.
