arXiv:2605.23591v1 Announce Type: cross Abstract: We introduce a model for neural scaling laws under sparse activations. In the model, test loss is often dominated by rare coordinates that are never observed in the training input. This mechanism induces a novel bottleneck absent from dense models. We derive the asymptotic population loss in both the underparameterized and overparameterized regimes, and show that the loss exhibits a double-descent peak near the interpolation threshold -- where the number of parameters is just sufficient to fit the training data -- resulting in a loss curve gove
The paper refines understanding of scaling laws due to increased research into sparse models and more efficient AI architectures, signaling a continuous evolution in AI development.
Understanding asymmetric scaling laws, particularly with sparse features, is crucial for optimizing future AI models, predicting performance, and managing computational resources more effectively, impacting the fundamental efficiency of AI development.
The theoretical understanding of neural network scaling now incorporates the critical role of sparse activations and the impact of unseen features during training, providing new levers for model design and optimization.
