Patchwise contrastive learning15 maximizes mutual information between input and output patches, enabling one-sided translation in unpaired settings. This is done using a multilayer patchwise contrastive loss that maximizes mutual information between corresponding input and output patches and its corresponding input patch (positive example \({v}^{+}\)) over other random patches (negative example \({v}^{-}\)).
