New model explains neural scaling laws with sparse features

By PulseAugur Editorial · [3 sources] ·

Researchers have developed a new model to understand neural scaling laws when sparse activations are present. This model reveals that test loss can be significantly influenced by rare data points not seen during training, creating a unique bottleneck. The study derives asymptotic population loss, showing a double-descent peak near the interpolation threshold and distinct scaling exponents for over- and under-parameterized regimes, with the gap dependent on sparsity.

    Improved Scaling Laws via Weak-to-Strong Generalization in Random Feature Ridge Regression

    arXiv:2603.05691v2 Announce Type: replace Abstract: It is increasingly common in machine learning to use learned models to label data and then employ such data to train more capable models. The phenomenon of weak-to-strong generalization exemplifies the advantage of this two-stag…

    Asymmetric Scaling Laws from Sparse Features

    arXiv:2605.23591v1 Announce Type: new 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 fr…
