Long-Tailed Question Answering in an Open World

1 code implementation11 May 2023 Yi Dai, Hao Lang, Yinhe Zheng, Fei Huang, Yongbin Li

A retrieve-then-rerank frame is further introduced to select in-context examples, which guild the LM to generate text that express knowledge for QA tasks.

Domain Incremental Lifelong Learning in an Open World

1 code implementation11 May 2023 Yi Dai, Hao Lang, Yinhe Zheng, Bowen Yu, Fei Huang, Yongbin Li

Specifically, we dedicate task-level prompts to capture task-specific knowledge to retain high LL performances and maintain instance-level prompts to learn knowledge shared across input samples to improve the model's generalization performance.

Robust video object tracking using particle filter with likelihood based feature fusion and adaptive template updating

no code implementations28 Sep 2015 Yi Dai, Bin Liu

In this solution, the bootstrap particle filter (PF) is initialized by an object detector, which models the time-evolving background of the video signal by an adaptive Gaussian mixture.
