Researchers have developed ROUTEBENCH, a new diagnostic benchmark designed to evaluate whether transformers can effectively route their in-context learning capabilities to different inductive biases. The benchmark features regimes favoring global shrinkage, sparsity, robustness, and locality, represented by various statistical models. Experiments with decoder-only transformers showed that a 306M parameter model achieved significant performance in routing and out-of-distribution generalization, even when tasks were presented in natural language.
