Improvement of generalization performance in fish species discrimination and catch prediction using echo sounder images

Abstract (in Japanese) (See Japanese page) 
(in English) A Set-Net fishery has various problems. One of the problems is that it is difficult to cope with fishing restrictions for specific fish species. This is because we do not know the type of fish and the amount of catch until the net is lifted from the sea. In the current fishery, the images of the fish are grasped by the fish finder. A system to estimate the fish species and catch is not established. It has become clear that previous studies cannot perform learning to improve generalization performance. In this study, the problems were clarified in the learning of fish species discrimination up to now by the experiment using a training data division method and artificial echo images. In addition, the possibility of catch prediction is examined by performing multi-class classification using the created clusters.
