Convergence speed of the network?

[twmht]

I tried to train the network with WIDERFACE, But I found that it's difficult to converge.

after the several epochs, both the precision and recall are less than 1%, did you have the similar problem?

it seems that the paper work is trained at least 200 epochs, did you train such a long epochs?

I tried to mask the small face of the training data (https://github.com/zeusees/FaceBoxes), but it does not speed up the training.
