Ñàkka gis ak LPIPS
Perceptual loss dafay natt ni ñaari nataal di nuru nit ñi ci méngale màndarga reso neuronal yu xóot yi ci barabu pixel yu ñor yi.
Résumé
It matters because pixel-by-pixel comparison wrongly punishes tiny shifts and blurs detail, while perceptual loss rewards sharp, realistic results.
