SDePER introduces a hybrid machine learning and regression framework that uses reference single-cell RNA sequencing (scRNA-seq) data. The method addresses platform effects between ST and scRNA-seq by enforcing a linear relationship, while also modeling sparsity and spatial correlations across capture spots. SDePER estimates cell-type proportions and improves tissue mapping by imputing cell-type compositions and gene expressions at unmeasured locations. Results on simulated and four real datasets show superior accuracy and robustness compared with existing approaches.","The Texas Medical Center Library  \nDigitalCommons@TMC  \n\n| Faculty and Staff Publications | Baylor College of Medicine |\n| --- | --- |\n| 10-14-2024\u003Cbr>SDePER: A Hybrid Machine Learning and Regression Method for Cell-Type Deconvolution of Spatial Barcoding-Based Transcriptomic Data\u003Cbr>Yunqing Liu Ningshan Li Ji Qi Gang Xu Jiayi Zhao\u003Cbr>Follow this and additional works at: [https://digitalcommons.library.tmc.edu/baylor_docs](https://digitalcommons.library.tmc.edu/baylor_docs)\u003Cbr>SeePnaertoe fBoilaoditaiol ahleanuotoera, Cell Phenomena, and Immunity Commons, Critical Care Commons, Internal Medicine Commons, Medical Cell Biology Commons, Pulmonology Commons, and the Sleep Medicine Commons\u003Cbr> |  |\n\nRecommended Citation  \nLiu, Yunqing; Li, Ningshan; Qi, Ji; Xu, Gang; Zhao, Jiayi; Wang, Nating; Huang, Xiayuan; Jiang, Wenhao; Wei, Huanhuan; Justet, Aurélien; Adams, Taylor S; Homer, Robert; Amei, Amei; Rosas, Ivan O; Kaminski, Naftali; Wang, Zuoheng; and Yan, Xiting, \"SDePER: A Hybrid Machine Learning and Regression Method for CellType Deconvolution of Spatial Barcoding-Based Transcriptomic Data\" (2024) .
