Table 1 Comparison of representative deep learning architectures for ECG signal analysis.
From: Research on cross-dataset cardiac signal domain generalization and feature interpretability
Architecture | Feature modeling | Temporal dependency | Limitations |
|---|---|---|---|
CNN | Local convolution | Short-term, fixed window | Limited context awareness |
RNN | Sequential recurrence | Captures long-term trends | Prone to gradient vanishing |
Transformer | Self-attention | Global, multi-scale | Requires larger training data |
