Avoiding Structural Failure Modes in Tabular Fair SSL: Online Primal-Dual Allocation under Confidence Gating

In three linesarXiv paper identifies two structural failure modes in fair tabular semi-supervised learning: Masking Collapse and Trivial Saturation. Proposes OPDA (Online Primal-Dual Allocation), an adaptive controller that dynamically adjusts fairness penalties without per-dataset tuning. Evaluated on Adult, ACSIncome, COMPAS benchmarks.
