Researchers have developed a new model to understand how neural networks scale when using sparse activations. This model reveals that test loss can be significantly influenced by rare features not present in the training data, 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 sparsity determining the gap.
