Researchers have introduced SMART, a novel spectral transfer method designed to enhance multi-task learning, particularly when the target dataset is small. This approach assumes spectral similarity between source and target models, allowing for transfer beyond traditional bounded-difference assumptions. SMART estimates the target coefficient matrix using structured regularization that incorporates spectral information from a source study, requiring only a fitted source model rather than raw data. The method has demonstrated improved estimation accuracy and robustness in simulations and analysis of single-cell data. AI
