Researchers have developed CHRep, a novel two-phase framework designed to improve the prediction of spatial gene expression from standard histology images. This method addresses challenges like slide-specific appearance variations and over-smoothing in predictions by learning a structure-aware representation during training. In the inference phase, a lightweight calibration module enhances cross-slide robustness without requiring extensive retraining of the main model. CHRep demonstrates significant improvements in gene-wise correlation and reductions in prediction errors compared to existing methods on multiple datasets. AI
