Suggestions for parameters
The followling important parameters need to be tuned for different datasets, which are:
self.weight1=0.1
self.weight2=0.1
self.mu=0.1
deep.dropout_keep_prob
Specifically, we suggest to tune "self.weight" among [0.001,0.005,0.01,0.02,0.05,0.1,0.2,0.5]. It's also acceptable to simply make the two weights the same. Generally, this parameter is related to the sparsity of dataset. If the dataset is more sparse, then a small value of negative_weight may lead to a better performance.
The coefficient parameter self.mu determines the importance of different tasks in joint learning. It can be tuned among [0.1,0.3,0.5,0.7,0.9].
Generally, the performance of our EATNN is very good. You can also contact us if you can not tune the parameters properly.
