ST-deconv improves spatial representation of adjacent spots, enhancing mapping accuracy.
In benchmarking, ST-deconv reduces root mean square error by 13% to 60%, achieving RMSE as low as 0.03.
The model incorporates contrastive learning and domain-adversarial networks to enhance deconvolution across diverse datasets.
Reconstructed tissue structures achieved a purity of 0.68 in mouse olfactory bulb and 0.76 in human pancreatic ductal adenocarcinoma.
