Scalable Neural-Probabilistic Answer Set Programming

Abstract

The goal of combining the robustness of neural networks and the expressiveness of symbolic methods has rekindled the interest in Neuro-Symbolic AI. Deep Probabilistic Programming Languages (DPPLs) have been developed for probabilistic logic programming to be carried out via the probability estimations of deep neural networks. However, recent SOTA DPPL approaches allow only for limited conditional probabilistic queries and do not offer the power of true joint probability estimation. In our work, we propose an easy integration of tractable probabilistic inference within a DPPL. To this end, we introduce SLASH, a novel DPPL that consists of Neural-Probabilistic Predicates (NPPs) and a logic program, united via answer set programming (ASP). NPPs are a novel design principle allowing for combining all deep model types and combinations thereof to be represented as a single probabilistic predicate. In this context, we introduce a novel +/− notation for answering various types of probabilistic queries by adjusting the atom notations of a predicate. To scale well, we show how to prune the stochastically insignificant parts of the (ground) program, speeding up reasoning without sacrificing the predictive performance. We evaluate SLASH on a variety of different tasks, including the benchmark task of MNIST addition and Visual Question Answering (VQA).

Introduction

This is the repository for SLASH, the deep declarative probabilistic programming language introduced within Neural-Probabilistic Answer Set Programming KR and Scalable Neural-Probabilistic Answer Set Programming JAIR. Link to the paper.

1. Prerequisites

1.1 Cloning SLASH and submodules

To clone SLASH including all submodules use:

git clone --recurse-submodules -j8 https://github.com/ml-research/SLASH

1.2 Anaconda

The environment.yaml provides all packages needed to run a SLASH program using the Anaconda package manager. To create a new conda environment install Anaconda (installation page) and then create a new environment using the following command:

conda env create -n slash -f environment.yml
conda activate env_dev
pip install git+https://github.com/ildoonet/pytorch-gradual-warmup-lr.git

The following packages are installed:

  • pytorch
  • clingo # version 5.5.1
  • scikit-image
  • scikit-learn
  • seaborn
  • tqdm
  • rtpt
  • tensorboard # needed for standalone slot attention
  • torchsummary
  • GradualWarmupSheduler

1.3 Virtual environment

To use virtualenv run the following commands. This creates a new virtual environment and installs all packages needed. Tested Python Versions 3.6. For using cuda version 10.x with pytorch remove the +cu113 version appendix in the requirements.txt file otherwise it will use CUDA version 11.3.

python3 -m venv slash_env
source slash_env/bin/activate
pip install --upgrade pip
python3 -m pip install -r requirements.txt -f https://download.pytorch.org/whl/torch_stable.html

1.4 Docker

Alternatively you can also run slash using docker. For this you first need to create an image using the provided Dockerfile.

To start create an image named slash and then run the container using that image. In the slash base folder execute:

docker build . -t slash:0.01
docker run --runtime=nvidia -e NVIDIA_VISIBLE_DEVICES=<GPU-ID> --ipc=host -it --rm  -v /$(pwd):/slash slash:1.0

2. Project Structure

--data: contains datasets after downloading
--src: source files which has its own readme. Go there for more details.

3. Getting started

Go visit the src/experiments/mnist_top_k folder to get familar with SLASH and run one of the training scripts.
