arXiv:2602.01083v2 Announce Type: replace Abstract: Weight-space learning studies neural architectures that operate directly on the parameters of other neural networks. Motivated by the growing availability of pretrained models, recent work has demonstrated the effectiveness of weight-space networks across a wide range of tasks. SOTA weight-space networks rely on permutation-equivariant designs to improve generalization. However, this may negatively affect expressive power, warranting theoretical investigation. Importantly, unlike other structured domains, weight-space learning targets maps op
This research addresses a fundamental theoretical question about the trade-offs in designing effective weight-space networks, a field gaining traction due to the prevalence of pre-trained models.
Understanding the expressive power limitations of permutation-equivariant designs is crucial for developing more robust and generalizable AI models, impacting the efficiency and applicability of future AI systems.
This theoretical investigation helps refine the design principles for weight-space networks, potentially leading to more advanced methods for transferring knowledge between AI models.
