COVAriance-Induced Fairness Gap Penalty for Subgroup-Fair Clustering

Kyungseon Lee, Hankyo Jeong, Kunwoong Kim, Kwanho Lee, Yongdai Kim

Fair clustering aims to make cluster assignments independent of sensitive attributes, but this goal becomes challenging when multiple sensitive attributes jointly define many subgroups. In such settings, directly extending existing fair clustering algorithms is computationally ex…

What Drives the Inlier-Memorization Effect? A Theory of Outlier Detection via Early Training Dynamics

Kunwoong Kim, Dongha Kim

Outlier detection (OD) aims to identify anomalous instances by learning the underlying structure of normal data (inliers), and is particularly challenging in fully unsupervised settings where no information about anomalies is available during training. Recent advances have levera…
