{"url":"/method/local-relation-layer","slug":"local-relation-layer","name":"Local Relation Layer","full_name":"Local Relation Layer","full_name_withheld":false,"description_markdown":"A **Local Relation Layer** is an image feature extractor that is an alternative to a [convolution](https://paperswithcode.com/method/convolution) operator. The intuition is that aggregation in convolution is basically a pattern matching process that applies fixed filters, which can be inefficient at modeling visual elements with varying spatial distributions. The local relation layer adaptively determines aggregation weights based on the compositional relationship of local pixel pairs. It is argued that, with this relational approach, it can composite visual elements into higher-level entities in a more efficient manner that benefits semantic inference.","description_state":"present","introduced_year":null,"introduced_by":{"title":null,"paper":null,"first_author":null,"n_authors":0,"url_abs":null,"archive_paper_url":null},"source":{"url":"http://arxiv.org/abs/1904.11491v1","title":"Local Relation Networks for Image Recognition","url_on_a_paper_host":true},"code_snippet_url":"https://github.com/gan3sh500/local-relational-nets/blob/master/lrnet.ipynb","code_snippet_url_on_a_code_host":true,"categories":[{"area":"Computer Vision","area_id":"computer-vision","collection":"Image Feature Extractors","url":"/methods/category/image-feature-extractors","pwc_aliases":[]}],"n_papers_tagged":3,"archive_num_papers":null,"papers_newest_first":[{"paper":null,"title":"Deep Distance Map Regression Network with Shape-aware Loss for Imbalanced Medical Image Segmentation","date":"2025-01-15","arxiv_id":"2501.09116","n_code_links":0,"syntology":null},{"paper":null,"title":"LR-Net: A Lightweight and Robust Network for Infrared Small Target Detection","date":"2024-08-05","arxiv_id":"2408.02780","n_code_links":0,"syntology":null},{"paper":"/paper/learning-from-ambiguous-labels-for-lung","title":"Learning from Ambiguous Labels for Lung Nodule Malignancy Prediction","date":"2021-04-23","arxiv_id":"2104.11436","n_code_links":1,"syntology":{"ran":3,"of":3,"unverified":0,"pointer_only":0}}],"papers_shown":3,"tasks":[{"task":"/task/image-segmentation","name":"Image Segmentation","papers":1},{"task":"/task/medical-image-analysis","name":"Medical Image Analysis","papers":1},{"task":"/task/medical-image-segmentation","name":"Medical Image Segmentation","papers":1},{"task":"/task/prediction","name":"Prediction","papers":1},{"task":"/task/segmentation","name":"Segmentation","papers":1},{"task":"/task/semantic-segmentation","name":"Semantic Segmentation","papers":1},{"task":"/task/tumor-segmentation","name":"Tumor Segmentation","papers":1},{"task":null,"name":"counterfactual","papers":1},{"task":"/task/regression-1","name":"regression","papers":1}],"tasks_shown":9,"n_tasks":9,"usage_by_year":[{"year":"2021","papers":1},{"year":"2024","papers":1},{"year":"2025","papers":1}],"row_source":"embedded","archive":{"source":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","archive_url":"https://paperswithcode.com/method/local-relation-layer"},"syntology_read_at":"2026-09-24T18:15:14+00:00"}
