Multi-Granularity Click Confidence Learning via Self-Distillation in Recommendation

no code implementations28 Sep 2023 Chong Liu, Xiaoyang Liu, Lixin Zhang, Feng Xia, Leyu Lin

Due to the lack of supervised signals in click confidence, we first apply self-supervised learning to obtain click confidence scores via a global self-distillation method.

FishMOT: A Simple and Effective Method for Fish Tracking Based on IoU Matching

1 code implementation6 Sep 2023 Shuo Liu, Lulu Han, Xiaoyang Liu, Junli Ren, Fang Wang, YingLiu, Yuanshan Lin

Wherein, a basic module performs target association based on IoU of detection boxes between successive frames to deal with morphological change of fish; an interaction module combines IoU of detection boxes and IoU of fish entity to handle occlusions; a refind module use spatio-temporal information uses spatio-temporal information to overcome the tracking failure resulting from the missed detection by the detector under complex environment.
