FSL ECG QA Dataset

FSL ECG QA Dataset is a benchmark dataset used in paper ["Electrocardiogram–Language Model for Few-Shot Question Answering with Meta Learning"] (https://arxiv.org/abs/2410.14464). It supports research in combining electrocardiogram (ECG) signals with natural language question answering (QA), particularly in few-shot and meta-learning scenarios.

Dataset Highlights

• 🧠 Task Diversification: Restructured ECG-QA tasks promote rapid few-shot adaptation.
• 🧬 Fusion Mapping: A lightweight multimodal mapper bridges ECG and language features.
• 🚀 Model Generalization: LLM-agnostic design ensures broad transferability and robustness.
