Hello @giho5374-AISchool, if you want to improve the performance of your pre-trained model with the additional 10,000 pieces of data, you have two options: 1) Fine-tuning the pre-trained model on the new data, or 2) Retraining the model on the entire 20,000 pieces of data. |
@glenn-jocher is there any guide to fine-tune the pre-trained yolov8 model? I need to enhance yolov8-seg model for one class of COCO (car). I already have the extra data (with the annotations) but it doesn't make sense to retrain yolov8 on COCO+the extra car dataset! |

Hello @SzaremehrjardiMT, you can refer to the Ultralytics Docs at https://docs.ultralytics.com/yolov5/ for a guide on fine-tuning the pre-trained YOLOv8 model. To enhance the YOLOv8-seg model for the "car" class, you can fine-tune the pre-trained model on your extra car dataset using transfer learning without retraining on the COCO dataset. This way, you can update the model specifically for the "car" class without starting from scratch. I hope this helps. Let me know if you have any further questions. |

Question
hello!
I trained using a pretrained model. We are in the process of learning with 10,000 pieces of data, and all previous learning is over.
Here, 10,000 additional pieces of data were collected, and there are a total of 20,000 pieces of data. I am wondering how to improve the performance of the model here.
Is there no other way than to train the newly collected 20,000 pieces of data from scratch without changing the class?
If the number of classes changes, do we have to train them all again?
Thank you for always.
