The workflow of ResPAN contains three key steps: generation of training data, adversarial training of the neural network, and generation of corrected data without batch effect.
WebAbstract. Single-cell transcriptomics is a versatile tool for exploring heterogeneous cell populations, but as with all genomics experiments, batch effects can hamper data integration and interpretation. The success of batch-effect correction is often evaluated by visual inspection of low-dimensional embeddings, which are inherently imprecise.
