Before revision:  We show that this inductive bias towards tree structures dramatically improves systematic generalization to out-of-distribution examples  compared to strong baselines on an arithmetic expressions benchmark as well as on CLOSURE, a dataset that focuses on systematic generalization of models for grounded question answering.
