How to tune the hyperparameters?

[PlusRoss]

Hi,

Thanks for your excellent work. In your paper, it says that "For all the compared approaches, we use 30% of inter-language links for training and 70% of them for testing". Do you also split validation data to tune the hyperparameters including the margin, beta, lr? If so, could you tell me how to split the data specifically so that we can get the optimal hyperparameters?
