# Neuro-Symbolic Agent Demo

This repository contains a demo for Neuro-Symbolic Agent (NeSA), which is specifically [Logical Optimal Action (LOA)](https://github.com/IBM/LOA).

## Setup

- Anaconda 4.10.3
- Tested on Mac and Linux

```bash
git clone --recursive git@github.com:IBM/nesa-demo.git
conda create -n nesa-demo python=3.8
conda activate nesa-demo
conda install pytorch=1.10.0 torchvision torchaudio -c pytorch
conda install gensim==3.8.3 networkx unidecode nltk=3.6.3
pip install -U spacy
python -m spacy download en_core_web_sm
python -m nltk.downloader 'punkt'
pip install -r requirements.txt
cp -r third_party/commonsense_rl/games static/

# Download models
wget -O results.zip https://ibm.box.com/shared/static/chr1vvgb70mmt2gr1yijlsw3g7fq2pgs.zip
unzip results.zip
rm -f results.zip

# Download AMR cache file
mkdir -p cache
wget -O cache/amr_cache.pkl https://ibm.box.com/shared/static/klsvx54skc5wlf35qg3klo35ex25dbb0.pkl
```

## Execute

```bash
export AMR_SERVER_IP=localhost
export AMR_SERVER_PORT=
python app.py --release
 ```

### If you want to train the model by yourself

- commonsense-rl (DL-only method)

```bash
cd third_party/commonsense_rl/
python -u train_agent.py --agent_type knowledgeaware --game_dir ./games/twc --game_name *.ulx --difficulty_level easy --graph_type world --graph_mode evolve --graph_emb_type glove --world_evolve_type manual --initial_seed 0 --nruns 1
```

- LOA (NeSA method)

```bash
cd third_party/loa/
# follow the setup steps in README.md
python train.py
cp results/loa-twc-dleasy-np2-nt15-ps1-ks6-spboth.pkl ../../results/
```

The paper presents an initial demonstration of logical optimal action (LOA) on TextWorld (TW) Coin collector, TW Cooking, TW Commonsense, and Jericho. In this version, the human player can select an action by hand and recommendation action list from LOA with visualizing acquired knowledge for improvement of interpretability of trained rules.
