GAProtoNet: A Multi-head Graph Attention-based Prototypical Network for Interpretable Text Classification

COLING 2025main

Pretrained transformer-based Language Models (LMs) are well-known for their ability to achieve significant improvement on text classification tasks with their powerful word embeddings, but their black-box nature, which leads to a lack of interpretability, has been a major concern. In this work, we i…

MobilePTX: Sparse Coding for Pneumothorax Detection Given Limited Training Examples

AAAI 2023technical

Point-of-Care Ultrasound (POCUS) refers to clinician-performed and interpreted ultrasonography at the patient's bedside. Interpreting these images requires a high level of expertise, which may not be available during emergencies. In this paper, we support POCUS by developing classifiers that can aid…
