SNR-ST-Mix: Sample-specific Neighborhood Regression Mixup for Augmented Spatial Transcriptomics Imputation with Deep Neural Network
arXiv:2606.08712v1 Announce Type: new Abstract: Purpose: Spatial transcriptomics (ST) enables gene expression measurements within the tissue context. However, these measurements are often noisy, low-resolution, and sparsely sampled, which limits the recovery of fine spatial structure. Deep neural networks have become powerful tools for expression imputation from histology, but their performance remains constrained by limited sample sizes and a lack of biologically informed augmentation. Most of the existing augmentation strategies for learning are designed for classification tasks rather than
The continuous advancements in deep neural networks and the increasing availability of spatial transcriptomics data enable researchers to develop more sophisticated methods for biological data analysis.
Improved imputation methods for spatial transcriptomics can lead to a more detailed understanding of tissue biology, disease mechanisms, and potentially new therapeutic targets, accelerating synthetic biology and drug discovery.
The ability to accurately recover fine spatial structures from noisy biological data could enhance our comprehension of cellular interactions and biological processes within tissues.
