DualMem: Bypassing the Objectness Bottleneck for Calibrated Unknown-Stream Filtering in Open-World Object Detection
Yingjun Xiao, Xi Chen, Gang Fang +1
Open-world object detection (OWOD) requires detectors to localize known classes while identifying unknown objects for future incremental learning. We find that the unknown predicti…

Evidence-Guided Unknown Rejection for High-Confidence Near-Known Unknowns
Xi Chen, Yingjun Xiao, Gang Fang
Open-set recognition systems face a neglected failure mode: high-confidence near-known unknowns, which lie outside the known label set but are close enough to known classes that a…

Community-aware evaluation and threshold calibration for open-set plankton image recognition
Xi Chen, Eryuan Huang, Yingjun Xiao +1
Automated plankton image recognition is increasingly used in aquatic ecosystem monitoring, but deployed classifiers inevitably encounter unseen taxa and non-target particles. Open-…
