CLEF: Clinically-Guided Contrastive Learning for Electrocardiogram Foundation Models

A recent study benchmarks three offline Multi-Objective Reinforcement Learning (MORL) algorithms—Conditioned Conservative Pareto Q-Learning, Adaptive CPQL, and a modified Pareto Efficient Decision Agent Decision Transformer—in critical care settings, particularly the Intensive Care Unit. This research aims to address the complexities of balancing patient survival with resource utilization through dynamic policy adaptation based on historical data.

A novel approach called Collaborative Learning for Disease Detection (CLDD) has been introduced, utilizing a graph-based deep learning model to detect diseases without extensive medical testing. This method leverages patient-disease interactions and demographic data from electronic health records, aiming to identify a wide range of diseases efficiently.

A new geometric-stochastic multimodal deep learning framework has been developed to predict vulnerability to Sudden Unexpected Death in Epilepsy (SUDEP) and acute ischemic stroke, integrating various physiological signals such as EEG, ECG, and fMRI. This approach utilizes advanced mathematical models to enhance predictive accuracy and interpretability of biomarkers derived from complex brain dynamics.

A new deep learning model named EfficientECG has been developed to enhance the classification of electrocardiogram (ECG) data, aiming to reduce misdiagnosis rates and alleviate the workload of medical professionals. This model leverages the EfficientNet architecture to efficiently process high-frequency, long-sequence ECG data, providing a promising alternative to existing methods.

A new method called Pic2Diagnosis has been developed for diagnosing cardiovascular diseases (CVD) directly from printed electrocardiogram (ECG) images, bypassing the need for digitization. This approach employs a two-step curriculum learning framework, achieving significant accuracy with an AUC of 0.9534 and an F1 score of 0.7801 on the BHF ECG Challenge dataset.

A novel three-stage training paradigm has been proposed to enhance the interpretability and trustworthiness of deep learning models in classifying electrocardiograms (ECGs) by transferring knowledge from multimodal clinical data into an ECG encoder. This approach utilizes a self-supervised, joint-embedding pre-training stage to enrich ECG representations with contextual clinical information, while only requiring the ECG signal during inference.
