Earlier unbounded context-free approaches tended to get stuck in poor solutions. Depth-bounded sequence models had their own limits: some could not express full grammar rules, and others needed very many parameters. Jin et al.… 2. **[The Importance of Category Labels in Grammar Induction with Child-directed Utterances](https://md.research.elamur.ai/free/en/papers/jin-2020-importance-category-labels-grammar-induction/)** *(2020 · 1 citation)* This paper concerns the evaluation of grammars that a model induces from raw text without supervision. Such grammars are usually compared only by their bracketing structure (unlabeled F1). Phrasal category labels are ignored, even though they are an essential part of a grammar.
