A Scaled-Up Empirical Study of Syntactic Language Models

Pengcheng Wang, Zhexuan Zhang, Chao Lou +1

Syntactic language models (SLMs) that generate sentences along with their syntactic tree structures have shown promise in both syntactic generalization and downstream tasks. Prior…

Dependency Transformer Grammars: Integrating Dependency Structures into Transformer Language Models

Yida Zhao, Chao Lou, Kewei Tu

Syntactic Transformer language models aim to achieve better generalization through simultaneously modeling syntax trees and sentences. While prior work has been focusing on adding…

Sparser is Faster and Less is More: Efficient Sparse Attention for Long-Range Transformers

Chao Lou, Zixia Jia, Zilong Zheng +1

Accommodating long sequences efficiently in autoregressive Transformers, especially within an extended context window, poses significant challenges due to the quadratic computation…

AMR Parsing with Causal Hierarchical Attention and Pointers

Chao Lou, Kewei Tu

Translation-based AMR parsers have recently gained popularity due to their simplicity and effectiveness. They predict linearized graphs as free texts, avoiding explicit structure m…

SeqGPT: An Out-of-the-box Large Language Model for Open Domain Sequence Understanding

Tianyu Yu, Chengyue Jiang, Chao Lou +12

Large language models (LLMs) have shown impressive ability for open-domain NLP tasks. However, LLMs are sometimes too footloose for natural language understanding (NLU) tasks which…

Improving Grammar-based Sequence-to-Sequence Modeling with Decomposition and Constraints

Chao Lou, Kewei Tu

Neural QCFG is a grammar-based sequence-tosequence (seq2seq) model with strong inductive biases on hierarchical structures. It excels in interpretability and generalization but suf…

Nested Named Entity Recognition as Latent Lexicalized Constituency Parsing

Chao Lou, Songlin Yang, Kewei Tu

Nested named entity recognition (NER) has been receiving increasing attention. Recently, (Fu et al, 2021) adapt a span-based constituency parser to tackle nested NER. They treat ne…

Unsupervised Vision-Language Parsing: Seamlessly Bridging Visual Scene Graphs with Language Structures via Dependency Relationships

Chao Lou, Wenjuan Han, Yuhuan Lin +1

Understanding realistic visual scene images together with language descriptions is a fundamental task towards generic visual understanding. Previous works have shown compelling com…
