Pseudo-Invertible Neural Networks Generalize Linear Solutions to Nonlinear Domain

Researchers have introduced Surjective Pseudo-invertible Neural Networks (SPNNs), a novel architecture designed to generalize the Moore-Penrose Pseudo-inverse to the nonlinear domain, specifically for neural networks. This new approach enables a tractable non-linear pseudo-inverse and formalizes Non-Linear Back-Projection (NLBP). The SPNNs are intended to expand the capabilities of zero-shot inverse problems, particularly by extending diffusion-based null-space projection methods to non-linear degradations. This advancement allows for the zero-shot inversion of complex information loss scenarios, including semantic abstractions, and offers precise semantic control over generative outputs without the need for retraining diffusion priors.
