New Score-Preserving Continual Lasso Method Tackles Catastrophic Forgetting

Researchers have developed a new method called score-preserving continual Lasso (SP-CL) to address catastrophic forgetting in continual learning for high-dimensional sparse linear regression. This approach separates sparse estimation from state transmission by preserving the historical squared-loss score, which allows the cumulative estimator to precisely recover a full-history Lasso minimizer under squared loss. SP-CL also incorporates a regularized current-task correction for related task-specific coefficients, achieving an offline source-assisted rate under specific conditions and providing decompositions to analyze information loss and specialization.
