Class-Incremental Training for saving training time #58

Open rose-jinyang opened 4 years ago

rose-jinyang commented 4 years ago

Hello How are you? Thanks for contributing this project. I have a question. Does this project support class-incremental training for saving training time? Let's suppose I've trained a model on the dataset with K classes for 5 days. If a new class is added into this dataset, should we train a model with the expanded dataset (K+1 classes) from begin? If so, it is so expensive, especially in case of object detection in retail store. That's because a new class of good is added frequently in retail store. Can we train a new model in short time with the original weight on the expanded dataset? I think that this is very important function. Please let me know if you have a willing to implement this. Thanks

That's a good direction to explore. However, we do not have plan to implement it if mmdet does not support this.
