This paper proposes the BTDT-MBO algorithm, a novel approach for data classification on highly imbalanced molecular datasets. The algorithm incorporates Merriman-Bence-Osher (MBO) methods and bidirectional transformers with distance correlation and decision threshold adjustments to improve performance on such datasets. By adjusting the classification threshold for the MBO algorithm and using an attention mechanism for self-supervised learning, the proposed method can effectively deal with class imbalance and outperform competing approaches.

Data scientists often struggle with imbalanced data sets in biology-related applications like disease diagnosis and drug discovery. This paper presents a solution to this problem by introducing the BTDT-MBO algorithm. The algorithm uses MBO methods, bidirectional transformers, and distance correlation to classify highly imbalanced molecular data sets. By adjusting thresholds and using self-supervised learning, the proposed method can help detect underrepresented classes more effectively.
