Also, a human study finds that showing lay-users our PCNN explanations improves their decision accuracy over showing only the top-1 class examples (as in prior work).","description_state":"present","introduced_year":null,"introduced_by":{"title":"PCNN: Probable-Class Nearest-Neighbor Explanations Improve Fine-Grained Image Classification Accuracy for AIs and Humans","paper":"/paper/advisingnets-learning-to-distinguish-correct","first_author":"Giang","n_authors":5,"url_abs":null,"archive_paper_url":"https://paperswithcode.com/paper/advisingnets-learning-to-distinguish-correct"},"source":{"url":"https://arxiv.org/abs/2308.13651v5","title":"PCNN: Probable-Class Nearest-Neighbor Explanations Improve Fine-Grained Image Classification Accuracy for AIs and Humans","url_on_a_paper_host":true},"code_snippet_url":null,"code_snippet_url_on_a_code_host":false,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"Image Models","url":"/methods/category/image-models","pwc_aliases":[]}],"n_papers_tagged":1,"archive_num_papers":1,"papers_newest_first":[{"paper":"/paper/advisingnets-learning-to-distinguish-correct","title":"PCNN: Probable-Class Nearest-Neighbor Explanations Improve Fine-Grained Image Classification Accuracy for AIs and Humans","date":"2023-08-25","arxiv_id":"2308.13651","n_code_links":2,"syntology":null}],"papers_shown":1,"tasks":[{"task":"/task/xai","name":"Explainable Artificial Intelligence (XAI)","papers":1},{"task":"/task/fine-grained-image-classification","name":"Fine-Grained Image Classification","papers":1},{"task":"/task/image-classification","name":"Image Classification","papers":1},{"task":"/task/image-classification","name":"image-classification","papers":1}],"tasks_shown":4,"n_tasks":4,"usage_by_year":[{"year":"2023","papers":1}],"row_source":"methods_table","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/pcnn-ranking"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
