SeqPO-SiMT: Sequential Policy Optimization for Simultaneous Machine Translation (2025.findings-acl)

Copied to clipboard

Challenge: SeqPO-SiMT is a new policy optimization framework for simultaneous machine translation that combines a tailored reward with a single step task.
Approach: They propose a new policy optimization framework that defines the simultaneous machine translation task as a sequential decision making problem with a tailored reward.
Outcome: The proposed framework outperforms the supervised fine-tuning model by 1.13 points while reducing the Average Lagging by 6.17 in the NEWSTEST2021 En Zh dataset.
DAPE V2: Process Attention Score as Feature Map for Length Extrapolation (2025.acl-long)

Copied to clipboard

Challenge: Extensive experiments demonstrate that treating attention as a feature map and applying convolution as . a processing method significantly enhances Transformer performance.
Approach: They propose to use the convolution operator to mimic the processing methods in computer vision to treat attention as a feature map and apply it to neighboring attention scores across different heads.
Outcome: The proposed model can be adapted to various attention-related models and achieves high performance.
