However, most applications in the real world have a long-tailed distribution, i.e., limited training examples in the majority of classes. The long-tailed challenge leads to a catastrophic drop in instance segmentation because the gradient of the head classes suppresses the gradient of the tail classes, leading to a bias towards the major classes. We propose LiCAM, a novel framework for long-tailed segmentation. It features an adaptive loss function named Moac Loss, which is adjustable during the training according to the monitored classification accuracy. LiCAM also cooperates with an oversampling technique named RFS, which alleviates the severe imbalance between head and tail classes. We conducted extensive experiments on the LVIS v1 dataset to evaluate LiCAM. With a coherent end-to-end training pipeline, LiCAM significantly outperforms other baselines. <\/jats:p>","DOI":"10.1142\/s0218126623500329","type":"journal-article","created":{"date-parts":[[2022,7,28]],"date-time":"2022-07-28T16:00:30Z","timestamp":1659024030000},"source":"Crossref","is-referenced-by-count":5,"title":["LiCAM: Long-Tailed Instance Segmentation with Real-Time Classification Accuracy Monitoring"],"prefix":"10.1142","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7759-1254","authenticated-orcid":false,"given":"Rongguang","family":"Ye","sequence":"first","affiliation":[{"name":"School of Mathematics and Statistics, Guangdong University of Technology, Guangzhou, Guangdong, P.
