WebIn the more general case of the dice-Haldane lattice model, the non-Hermitian skin effect can be caused by both gain and loss or non-reciprocity. Fascinatingly, the direction of localization of the eigenstates depends on the nature and strength of the non-Hermiticity. Webloss = 1. - ((2 * intersection + eps) / (union + eps)) This causes all zero-input predictions to always maximize the loss even if it's completely correct.
