This addresses a long-standing gap between theoretical bounds and practical neural network performance.
Researchers discovered that language models forget learned rules midway through training despite continued evidence in data—a phenomenon called 'natural ungrokking.' The survival of rules depends predictably on how often they appear in training data, and attempts to restore forgotten rules through data manipulation fail despite successfully destroying them, revealing asymmetric control over model knowledge.
Researchers demonstrate that neural networks using trainable rational activation functions achieve exponentially better parameter efficiency and expressivity compared to standard activations like ReLU, Sigmoid, and Tanh.
