SNR-ST-Mix: Sample-specific Neighborhood Regression Mixup for Augmented Spatial Transcriptomics Imputation with Deep Neural Network
Researchers have developed SNR-ST-Mix, a novel data augmentation framework for spatial transcriptomics imputation using deep neural networks. This method addresses limitations in current augmentation strategies by ensuring that mixed samples preserve local biological structure and spatial smoothness. Experiments show that SNR-ST-Mix outperforms existing methods without increasing computational complexity, leading to improved prediction performance. AI
