Does Traversal Order Matter? A Systematic Study of Tree Traversal Methods in Transformer Grammars

Zongru Liu, Pengyu Ji, Pengcheng Wang +1

Transformer Grammars (TGs) enhance language modeling by incorporating syntactic tree structures. Despite the potentially significant impact on model performance of how syntactic tr…

Unsupervised Morphological Tree Tokenizer

Qingyang Zhu, Xiang Hu, Pengyu Ji +2

As a cornerstone in language modeling, tokenization involves segmenting text inputs into pre-defined atomic units. Conventional statistical tokenizers often disrupt constituent bou…

Generative Pretrained Structured Transformers: Unsupervised Syntactic Language Models at Scale

Xiang Hu, Pengyu Ji, Qingyang Zhu +2

A syntactic language model (SLM) incrementally generates a sentence with its syntactic tree in a left-to-right manner. We present Generative Pretrained Structured Transformers (GPS…
