Research direction
Check the PaddleDetection documentation and codebase for anchor clustering support in PPYOLO and PPYOLOv2. Look for the anchor clustering method V2 implementation, and compare the default anchors with the clustered ones. Investigate why accuracy decreases and report findings. Relevant files may include configs and model files under 'configs/ppyolo/' and 'ppdet/modeling/architectures/'.
