Title: NNiT: Width-Agnostic Neural Network Generation with Structurally Aligned Weight Spaces

Abstract:
arXiv:2603.00180v2 Announce Type: replace-cross Abstract: Generative modeling of neural network parameters is often tied to architectures because standard parameter representations rely on known weight-matrix dimensions. Generation is further complicated by permutation symmetries that allow networks to model similar input-output functions while having widely different, unaligned parameterizations. In this work, we introduce Neural Network Diffusion Transformers (NNiTs), which generate weights in
