UAV Target Detection Algorithm Based on Improved YOLOv8
IEEE Access, 2023 Since UAVs usually fly at higher altitudes, resulting in a more significant proportion of small targets after imaging, this poses a challenge to the target detection algorithm at this stage; in addition, the high-speed flight of UAVs causes a sense of ...

Target-Aware Data Augmentation for Stance Detection
, 2021 The goal of stance detection is to identify whether the author of a text is in favor of, neutral or against a specific target. Despite substantial progress on this task, one of the remaining challenges is the scarcity of annotations. Data augmentation is
