It’s important to note that the exact working principles and improvements can vary between different YOLO versions. Newer versions often introduce architectural changes, optimizations, and new techniques to enhance accuracy and speed. If YOLO versions 7 and 8 have been developed since my last update, you must refer to the official research papers, documentation, or other authoritative sources to understand their specific working principles and improvements. Additionally, you might find code implementations and tutorials that explain the details of these newer versions in practical terms.1
