A recent experiment explored whether non-neural methods could achieve language model-like behavior, specifically testing a full hierarchical Pitman-Yor model against a baseline transformer. The results indicated that while the Pitman-Yor model showed improvements over simpler non-neural methods, it did not meet the performance bar set by the transformer. The experiment found that the rate of accuracy improvement with increased data saturated for the Pitman-Yor model, similar to other non-neural approaches, suggesting that a different kind of state representation, rather than better fitting of n-gram hierarchies, is needed for non-neural models to compete.
