Fair CCA for Fair Representation Learning: An ADNI Study
This work addresses fairness in neuroimaging studies, providing a method for unbiased analysis, though it appears incremental by building on existing fair CCA approaches.
The paper tackled the problem of ensuring fairness in canonical correlation analysis for representation learning, proposing a method that maintains high correlation performance while improving fairness in classification tasks, as validated on synthetic and ADNI data.
Canonical correlation analysis (CCA) is a technique for finding correlations between different data modalities and learning low-dimensional representations. As fairness becomes crucial in machine learning, fair CCA has gained attention. However, previous approaches often overlook the impact on downstream classification tasks, limiting applicability. We propose a novel fair CCA method for fair representation learning, ensuring the projected features are independent of sensitive attributes, thus enhancing fairness without compromising accuracy. We validate our method on synthetic data and real-world data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), demonstrating its ability to maintain high correlation analysis performance while improving fairness in classification tasks. Our work enables fair machine learning in neuroimaging studies where unbiased analysis is essential. Code is available in https://github.com/ZhanliangAaronWang/FR-CCA-ADNI.
