Cluster Frequency Conformal Prediction for Local Coverage

Tomer Lavi, Bracha Shapira, Nadav Rappoport

Conformal prediction provides distribution-free coverage guarantees, but in many-class classification it may still under-cover specific classes or subpopulations, preventing safe d…

Trajectory-Based Difficulty Scoring for Reliable Learning on Tabular Data

Tomer Lavi, Bracha Shapira, Nadav Rappoport

Gradient-boosted trees achieve strong performance on tabular data, yet often leave a long tail of poorly predicted instances. We introduce a Trajectory-based Difficulty Score (TDS)…

Clustered Calibration: Representation-Aware Probability Calibration via Learned Subpopulations

Tomer Lavi, Bracha Shapira, Nadav Rappoport

Ensuring that predicted probabilities align with observed frequencies is critical in high-stakes domains such as clinical decision support, autonomous driving and financial risk as…
