Reproducibility Variable Result LLM Response
Research Type Experimental We perform an empirical evaluation using 12-lead ECG signals from thousands of patients, and show that we are able to reconstruct the signals in such way that enables accurate clinical diagnosis.

Pseudocode No The paper describes the steps for reconstruction using mathematical formulations and descriptive text, but it does not provide a formal pseudocode block or algorithm block.
Open Source Code Yes We share the code for the reproducibility of our results 1Link anonymized
Open Datasets Yes The Georgia 12-lead ECG dataset, referred to as G12EC, was introduced in the 12-lead ECG Physionet Challenge 2020 (Alday et al., 2020) and is considered one of the largest public 12-lead ECG datasets.
Dataset Splits No The paper mentions a validation set was used for model selection ("the final model being the one with the best accuracy on the validation set") but does not provide specific split percentages or sample counts for it.
Hardware Specification No The paper does not provide specific hardware details (e.g., GPU/CPU models, memory amounts) used for running its experiments.
Software Dependencies No The paper mentions using a "Residual Neural Network (He et al., 2016)" and "Adam Optimizer", but does not specify version numbers for any software dependencies.
Experiment Setup Yes The network was trained by feeding 12-lead ECG batches of size 128 from the training data. The binary cross-entropy loss was minimized using Adam Optimizer with initial learning rate 0.0001. The training ran for 100 epochs, with the final model being the one with the best accuracy on the validation set.
