The package provides methods for incorporating cell type information into the dimensionality reduction process, enabling improved visualization and downstream analysis of single-cell data while preserving biological structure. CellMentor employs a unique loss function that simultaneously minimizes variation within known cell populations while maximizing distinctions between different cell types, enabling effective transfer of learned patterns from labeled reference datasets to new unlabeled data.https://github.com/r-universe/bioc/actions/runs/39229804834Fri, 22 May 2026 10:03:17 GMTCellMentor1.1.2successhttps://bioc.r-universe.devhttps://github.com/bioc/CellMentorCellMentor_vignette.RmdCellMentor_vignette.htmlIntroduction to CellMentor2025-10-27 19:17:302026-05-19 14:04:01
