WebK-means is a clustering algorithm—one of the simplest and most popular unsupervised machine learning (ML) algorithms for data scientists. What is K-Means? Unsupervised learning algorithms attempt to ‘learn’ patterns in unlabeled data sets, discovering similarities, or regularities. Common unsupervised tasks include clustering and association. WebSep 26, 2024 · To handle the problem of low detection accuracy and missed detection caused by dense detection objects, overlapping, and occlusions in the scenario of complex construction machinery swarm operations, this paper proposes a multi-object detection method based on the improved YOLOv4 model. Firstly, the K-means algorithm is used to …
