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

paper

code

datasets

This repository contains the models for the paper Weight Space Representation Learning on Diverse NeRF Architectures, accepted at ICLR 2026. 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.
