The Emergence of Chunking Structures with Hierarchical RNN

Zijun Wu, Anup Anand Deshmukh, Yongkang Wu +2

In Natural Language Processing (NLP), predicting linguistic structures, such as parsing and chunking, has mostly relied on manual annotations of syntactic structures. This paper in…

Revisiting Intermediate-Layer Matching in Knowledge Distillation: Layer-Selection Strategy Doesn't Matter (Much)

Zony Yu, Yuqiao Wen, Lili Mou

Knowledge distillation (KD) is a popular method of transferring knowledge from a large "teacher" model to a small "student" model. Previous work has explored various layer-selectio…

LoRAQuant: Mixed-Precision Quantization of LoRA to Ultra-Low Bits

Amir Reza Mirzaei, Yuqiao Wen, Yanshuai Cao +1

Low-Rank Adaptation (LoRA) has become a popular technique for parameter-efficient fine-tuning of large language models (LLMs). In many real-world scenarios, multiple adapters are l…

Feeding Two Birds or Favoring One? Adequacy-Fluency Tradeoffs in Evaluation and Meta-Evaluation of Machine Translation

Behzad Shayegh, Jan-Thorsten Peter, David Vilar +4

We investigate the tradeoff between adequacy and fluency in machine translation. We show the severity of this tradeoff at the evaluation level and analyze where popular metrics fal…

Exploring Model Invariance with Discrete Search for Ultra-Low-Bit Quantization

Yuqiao Wen, Yanshuai Cao, Lili Mou

Large language models have been increasing in size due to their success in a wide range of applications. This calls for a pressing need to reduce memory usage to make them more acc…

Error Diversity Matters: An Error-Resistant Ensemble Method for Unsupervised Dependency Parsing

Behzad Shayegh, Hobie H. -B. Lee, Xiaodan Zhu +2

We address unsupervised dependency parsing by building an ensemble of diverse existing models through post hoc aggregation of their output dependency parse structures. We observe t…
