New CLASSO algorithm for constrained LASSO verified in Lean 4

By PulseAugur Editorial · [1 sources] ·

Researchers have developed CLASSO, a new algorithm for solving the constrained LASSO problem. This method uses a primal path-following approach to efficiently determine coefficient changes and active constraints. The algorithm's correctness and finite traversal of the solution path have been formally verified using the Lean 4 programming language, and its implementation shows high accuracy on synthetic and benchmark datasets.

    CLASSO: a practical primal path-following algorithm for the constrained LASSO

    arXiv:2610.17024v1 Announce Type: cross Abstract: We present CLASSO, a path-following method for the LASSO subject to general linear equality and inequality constraints. The local direction is obtained from a quadratic programme on an augmented active set, which determines both t…
