Margin-based sampling in high dimensions: When being active is less efficient than staying passive

no code implementations1 Dec 2022 Alexandru Tifrea, Jacob Clarysse, Fanny Yang

It is widely believed that given the same labeling budget, active learning (AL) algorithms like margin-based active learning achieve better predictive performance than passive learning (PL), albeit at a higher computational cost.

Maximizing the robust margin provably overfits on noiseless data

Numerous recent works show that overparameterization implicitly reduces variance, suggesting vanishing benefits for explicit regularization in high dimensions.
