Hi
Do you evaluate the accuracy?

Hi @lilaczhou I think they have noted:
To best of our knowledge, the F1 score of BP4D (3-fold testing protocol) is 63%, this is state-of-the-art result.

[lilaczhou]

Except the F1 score, I want to know if you evaluate the accuracy score?

I got it.. no Idea ... I have several questions too, hope he answer...

All the related works report the average F1 score, rather than average.
Because the accuracy is not fair in the case that the data distribution over different AU classes are imbalanced. However, F1 score considers this case.

You can read the experimental section of my paper to get all the F1 scores.

Execuse me, could you share me the BP4D database?

@cug-lucifer I have BP4D database, but it must sign an agreement with the creator of BP4D, otherwise it will have law issue. You can contact with BP4D creator.
