BranchNorm: Robustly Scaling Extremely Deep Transformers

ACL 2024findings

Recently, DeepNorm scales Transformers into extremely deep (i.e., 1000 layers) and reveals the promising potential of deep scaling. To stabilize the training of deep models, DeepNorm attempts to constrain the model update to a constant value. Although applying such a constraint can benefit the early…

Instruction Position Matters in Sequence Generation with Large Language Models

ACL 2024findings

Large language models (LLMs) are capable of performing conditional sequence generation tasks, such as translation or summarization, through instruction fine-tuning. The fine-tuning data is generally sequentially concatenated from a specific task instruction, an input sentence, and the corresponding…

Towards Multiple References Era – Addressing Data Leakage and Limited Reference Diversity in Machine Translation Evaluation

ACL 2024findings

Recent research has shown a weak correlation between n-gram-based metrics and human evaluations in machine translation task, particularly when evaluating large language models (LLMs). Additionally, the data leakage risk in LLMs may cause an overestimation problem when evaluating LLMs on downstream t…
