Researchers have developed two novel hybrid methods for tabular data imputation, named NuclearForest and SoftForest. These methods combine low-rank initialization techniques like Singular Value Thresholding (SVT) and SoftImpute with a non-iterative Random Forest refinement. The approach aims to improve imputation accuracy and significantly reduce computational costs compared to existing iterative methods. Extensive benchmarking shows that NuclearForest and SoftForest achieve comparable or superior results to state-of-the-art methods like MissForest, with speedups of approximately 5.81 and 9.52 times, respectively.
