Kenan Dai, Yunhua Zhang, Dong Wang, Jianhua Li, Huchuan Lu, Xiaoyun Yang
2020 2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)  
Long-term visual tracking has drawn increasing attention because it is much closer to practical applications than short-term tracking.  ...  Most top-ranked long-term trackers adopt the offline-trained Siamese architectures, thus, they cannot benefit from great progress of short-term trackers with online update.  ...  In this work, we attempt to address this dilemma by designing a high-performance long-term tracker with a meta-updater.  ...

2021 arXiv   pre-print
We show that the meta-learning process results in an appreciably faster learning, resulting in significantly fewer lost tracks than a conventional learning approach equipped with an uninformative prior  ...  This paper studies a Bayesian meta-learning model for radar waveform selection which seeks to learn an inductive bias to quickly optimize tracking performance across a class of radar scenes.  ...  However, the performance benefits in terms of average performance are not as substantial as in terms of worst-case metrics, such as lost tracks.  ...

Charles E. Thornton, R. Michael Buehrer, Anthony F. Martone
2022 arXiv   pre-print
Finally, we examine the potential performance benefits and practical challenges associated with online meta-learning for waveform-agile tracking.  ...  One way to address this problem is to bias a learning algorithm strategically by exploiting high-level structure across tracking instances, referred to as meta-learning.  ...  This is because the radar begins each new track with updated prior assumptions, reducing data requirements. For this reason, meta-learning is intimately connected with Bayesian statistics.  ...
