Merging Weak and Active Supervision for Semantic Parsing (WASSP)

This repository contains the experiment code for the AAAI 2020 paper, Merging Weak and Active Supervision for Semantic Parsing.

Note: Ansong Ni has moved from CMU to Yale, please see his new contact info here.

Memory Augmented Policy Optimization (MAPO)

The semantic parsing model we used in our paper is MAPO. If you are looking for more information about MAPO, please refer to this paper and repository.

Preparation

To run our code, you need to set up the environment with the following steps:

# Go to a convenient location and clone this repo
git clone git@github.com:niansong1996/wassp
cd wassp

# Create the conda environment and install the requirements
conda create --name wassp python=2.7
source activate wassp
pip install requirements.txt

Then you need to download the data and pretrained MAPO models (which we use as baseline) from here. Unzip the downloaded file and put the resulting data folder under the wassp directory so it looks like this:

wassp
    ├── data
        └── ...
    ├── images
    ├── nsm
    ├── nsm.egg-info
    └── table
        └── ...

Or you could simply do:

cd wassp
bash get_data.sh

Finally you need to run setup.py so the dependencies are set correctly:

source activate wassp
cd wassp
python setup.py develop

Running experiments

Starting WikiSQL Experiment

source activate wassp
cd wassp/table/wikisql/
./run.sh active_learning your_experiment_name

Starting WikiTableQuestions Experiment

source activate wassp
cd wassp/table/wtq/
./run.sh active_learning your_experiment_name

Different settings for active learning

To change:

  • Active learning selection heuristic;
  • Forms of extra supervision;
  • Querying budget

please see relevant options described in the run.sh file.

Hardware

Our experiments are run on g3.4xlarge AWS instance, which has 16 vCPUs and 122 GiB of memory as well as a M60 GPU with ~8GiB of GPU memory. It takes ~10 hours to run WikiSQL experiments and ~4 hours to run WikiTableQuestions experiments.

If you are running the experiments on a machine with less CPU Computing Power/RAM, we recommend you to decrease the n_actors(default=30) parameter in run.sh.

Monitoring training process

You can monitor the training process with tensorboard, specifically:

source activate wassp
cd wassp/data/wikisql # or wtq, depending on which dataset are you using
tensorboard --logdir=ouput

To see the tensorboard, got to [your AWS public DNS]:6006 and avg_return_1 is the main metric (accuracy).

An example of our training process is shown in the screenshot below:
