Recently, in the field of visual object tracking, tracking algorithms combined with segmentation have achieved impressive results while using mask to label targets VOT2020 dataset. Most trackers get by increasing resolution through multiple upsampling modules and gradually summing features backbone network. However, this refinement pathway does not fully consider spatial information features, t...

Many induction problems, such as on-line customer profiling, include missing data that can be acquired at a cost, such as incomplete customer information that can be filled in by an intermediary. For building accurate predictive models, acquiring complete information for all instances is often prohibitively expensive or unnecessary. Randomly selecting instances for feature acquisition allows a ...
