STARK denoises spatial transcriptomics images via adaptive regularization

arXiv — stat.MLMonday, December 15, 2025 at 5:00:00 AM
  • A novel method called STARK has been developed to denoise spatial transcriptomics images, enhancing the identification of cell types at ultra-low sequencing depths. This technique employs adaptive regularization and kernel ridge regression, updating a spatial graph iteratively to improve image quality and gene expression interpolation.
  • The introduction of STARK is significant as it addresses challenges in spatial transcriptomics, particularly in low-depth sequencing scenarios, allowing for more accurate cellular identity mapping and gene expression analysis.
  • This advancement aligns with ongoing efforts in the field to refine spatial transcriptomics methodologies, as researchers explore various frameworks and models to enhance gene expression predictions and integrate complex biological data, reflecting a broader trend towards improved precision in cellular analysis.
