Validation Loss did not decrease in the HMDB51 notebook? #25
Comments
Can you provide more information? Maybe a log of the training. |
The notebook functions correctly, also I use the networks daily. It's unlikely these are problem related to part of the code of this repository. If you provide a colab short script that reproduces the problem I will look at it. |
I will run your notebook with HMDB51 for 10 epochs and show to you a log of the training. Because I used the same function for my own dataset and got the same problem. I don't think it can converges from the first epoch with many datasets. When you train Movinet with your dataset, the validation loss decreases or not? |
@nguyenquibk1996 Did I miss any key points during finetuning or could you give any clues about this? |
I think the dataset is primary cause, and the data processing method(one clip or multiple clips sampled from one video) is second cause. I have train the X3D and SlowFast on the HMDB51 by mmaction2(default config samples one clip from one video), top1 acc is also about 30%, and validation loss can decrease. |
Have you tried any other datasets? BTW, I see in mmaction2 there's no training codes of X3D, could you tell me how to get the codes? |
I have tried UCF101, the top1 can over 45%. I write the codes of X3D by myself(of course refer to existing codes ) |
I trained your HMDB51 notebook in 10 epochs but the validation loss did not decrease? Why did it happened?
