Self-paced learning strategy with easy sample prior based on confidence for the flying bird object detection model training
摘要
To avoid the impact of hard samples on the training of the Flying Bird Object Detection model (FBOD model), the Self-Paced Learning strategy with Easy Sample Prior Based on Confidence (SPL-ESP-BC) is proposed. First, the loss-based Minimizer Function is improved and a confidence-based one is introduced, making it more suitable for one-category object detection. Second, to enable early-stage judgment of easy and hard samples using SPL, an SPL strategy with Easy Sample Prior (ESP) is put forward. The FBOD model is initially trained with easy samples via the standard strategy and then continues with all samples using SPL. Combining ESP and the confidence-based Minimizer Function, the SPL-ESP-BC strategy is formed. Training the FBOD model with this strategy helps it learn flying bird object features in surveillance videos from easy to hard. Experimental results show that compared to the non-distinguishing standard training strategy, the Average Precision at 50% Intersection-over-Union (
