Studying the Inductive Biases of RNNswith Synthetic Variations of Natural Languages
Table 1: Results of the polypersonal agreement experiments. “Joint” refers to multitask prediction of subject and object plurality.

, agreement markers on verbs other than the prediction target could plausibly help predict the features on the target verb. In a preliminary experiment, we did not observe clear differences between different verb marking schemes (e.g., avoiding marking agreement on verbs other than the prediction target). For consistency, we remove plurality markers from English verbs before adding our suffixes (for example, by replacing has with have).
