arXiv:2606.03990v1 Announce Type: cross Abstract: We investigate whether neuron populations within neural networks evolve predictably with scale, extending scaling laws beyond macroscopic observables such as loss. To probe this question, we study Rosetta Neurons, a previously characterized class of neurons whose activation patterns are similar across independently trained models (Dravid et al., 2023). In separate analyses of language models up to 30B parameters and vision models up to 5B parameters, we observe that the population of Rosetta Neurons follows a sublinear power law in model size,
This research builds on earlier work (Dravid et al., 2023) by investigating the sublinear scaling of 'Rosetta Neurons' with increasing model size, offering new insights into how neural networks function internally at scale.
Understanding how neuron populations evolve predictably with model scale provides crucial insights into the fundamental mechanisms of AI, moving beyond macroscopic loss functions to the microscopic behavior of network components.
This research shifts the focus from purely observing emergent capabilities to understanding the underlying architectural scaling principles and internal component behavior of large AI models, refining how we think about and design them.
