Parameter-Efficient Token Embedding Editing for Clinical Class-Level Unlearning

arXiv:2603.19302v1 Announce Type: new Abstract: Machine unlearning is increasingly important for clinical language models, where privacy regulations and institutional policies may require removing sensitive information from deployed systems without retraining from scratch. In practice, deletion requests must balance effective forgetting…

BrainSCL: Subtype-Guided Contrastive Learning for Brain Disorder Diagnosis

arXiv:2603.19295v1 Announce Type: new Abstract: Mental disorder populations exhibit pronounced heterogeneity — that is, the significant differences between samples — poses a significant challenge to the definition of positive pairs in contrastive learning. To address this, we propose a subtype-guided…

Diminishing Returns in Expanding Generative Models and Godel-Tarski-Lob Limits

arXiv:2603.19687v1 Announce Type: cross Abstract: Modern generative modelling systems are increasingly improved by expanding model capacity, training data, and computational resources. While empirical studies have documented such scaling behaviour across architectures including generative adversarial networks, variational autoencoders, transformer-based models, and…

Minimax Generalized Cross-Entropy

arXiv:2603.19874v1 Announce Type: cross Abstract: Loss functions play a central role in supervised classification. Cross-entropy (CE) is widely used, whereas the mean absolute error (MAE) loss can offer robustness but is difficult to optimize. Interpolating between the CE and MAE…
