In the following, we will guide you how to use this repository step by step.

Architecture

Preparation

Our code is based on PyTorch 1.1 and runnable for both windows and ubuntu server. Required python packages:

• numpy==1.16.2
• tqdm==4.32.2
• scipy==1.2.1
• torch==1.1.0
• ordered-set==3.1.1

We highly suggest you using Anaconda to manage your python environment.

How to Run it

The script train.py acts as a main function to the project. For reproducing the results reported in our paper, We suggest you the following hyper-parameter setting for ATIS dataset:

    python train.py -wed 256 -ehd 256 -aod 128 

Similarly, for SNIPS dataset, you can also consider the following command:

    python train.py -wed 32 -ehd 256 -aod 128

Due to some stochastic factors, It's necessary to slightly tune the hyper-parameters using grid search. If you have any question, please issue the project or email me and we will reply you soon.
