Children learn various levels of linguistic structure concurrently, yet most existing mod- els of language acquisition deal with only a single level of structure, implicitly assum- ing a sequential learning process. Developing models that learn multiple levels simultane- ously can provide important insights into how these levels might interact synergistically dur- ing learning. Here, we present a model that jointly induces syntactic categories and mor- phological segmentations by combining two well-known models for the individual tasks. We test on child-directed utterances in English and Spanish and compare to single-task base- lines. In the morphologically poorer language (English), the model improves morphological segmentation, while in the morphologically richer language (Spanish), it l...
