This file realized DNN Query Classification based on DNN and GRU RNN. Some features in this program: * Using GRU RNN to understand the context of a specific word in a sentence * Using skip layers to learn the linear relations between regular features and output *
- Train Query Size:46000+
- Test Query Size:6000+
* max query length:20
* bach size: 10
* dropout 0.3
