Weight Space Representation Learning on Diverse NeRF Architectures (ICLR 2026)

This repository contains the models for the paper Weight Space Representation Learning on Diverse NeRF Architectures. The paper proposes a framework that is capable of processing NeRFs with diverse architectures (MLPs, tri-planes, and hash tables) by training a graph metanetwork to obtain an architecture-agnostic latent space.
