🌟 Summary

The Ultralytics v8.3.51 release introduces improved robustness for training batch size optimization, documentation enhancements, new features like a security alarm system, and updates to facilitate the transition from YOLOv8 to YOLO11. 🚀

📊 Key Changes

• Improved Batch Size Calculation:
  • Automated batch size determination now uses logarithmic polynomial fitting for better accuracy. 🧮
  • Stricter checks ensure safe memory usage and prevent crashes due to misconfigurations. ✅
• Hyperparameter Tuning:
  • Added default hyperparameter search spaces and clear examples in documentation for easier customization. 🛠️
  • Updated training process to improve reliability by using shell=True for subprocess execution. ⚙️
• YOLO11 Integration:
  • Updated examples, references, and documentation to reflect the transition from YOLOv8 to YOLO11. 📚
  • Enhanced support for SAHI (Slicing Aided Hyper Inference) with YOLO11 models.
• New Security Alarm System:
  • Added a ready-to-use, customizable security alarm system solution leveraging YOLO11. Includes email alerts when detections exceed thresholds. 🛡️
• Expanded Export Options:
  • New formats supported, including MNN and Sony IMX500, enhancing deployment flexibility for diverse platforms. 🎉
