PRISM a diagnostic framework for parametric recall degradation in quantized large language models

Post-training quantization (PTQ) is the standard method for deploying large language models (LLMs), though it is widely assumed to degrade model quality uniformly. Although, this assumption masks how quantization uniquely affects different mechanisms, particularly the balance between a model’s internal parametric memor...

FedBound a boundary aware optimization strategy for federated medical image segmentation under non IID data

Medical image segmentation is essential for computer-aided diagnosis and treatment planning. Privacy constraints impede centralized training using medical images from diverse healthcare organizations. Federated learning (FL) is developed to facilitate collaborative model training without sharing patient information. Ho...
