Deep representation learning methods have shown promising performance in different domains, including NLP, image analysis, and healthcare modeling. In healthcare, researchers focus on mitigating data sparsity and high dimensionality and modeling the complex short and long-term dependencies in electric health records (EHR by different representation learning methods. These models are used as feature extractors for few-shot learning and various other downstream tasks. Ensuring fairness in machine learning is extremely important to achieve health equity across different groups in society. Different approaches and frameworks address bias and fairness issues, such as anti-classification, parity, and calibration.

The ultimate goal of this project is to analyze the effect of different EHR representation learning methods on fairness and look for representations that are agnostic to the patients’ sensitive attributes or have low subgroup gaps in downstream tasks.
