T-CIL: Temperature Scaling using Adversarial Perturbation for Calibration in Class-Incremental Learning

no code implementations28 Mar 2025 Seong-Hyeon Hwang, Minsu Kim, Steven Euijong Whang

The key idea of T-CIL is to perturb exemplars more strongly for old tasks than for the new task by adjusting the perturbation direction based on feature distance, with the single magnitude determined using the new-task validation set.

Quilt: Robust Data Segment Selection against Concept Drifts

no code implementations15 Dec 2023 Minsu Kim, Seong-Hyeon Hwang, Steven Euijong Whang

However, we contend that explicitly utilizing the drifted data together leads to much better model accuracy and propose Quilt, a data-centric framework for identifying and selecting data segments that maximize model accuracy.
