Learning Symbolic Rules for Reasoning in Quasi-Natural Language

Example proof

Code for the paper:

Learning Symbolic Rules for Reasoning in Quasi-Natural Language
Transactions on Machine Learning Research (TMLR), 2023
Kaiyu Yang and Jia Deng

@article{yang2023metaqnl,
  title={Learning Symbolic Rules for Reasoning in Quasi-Natural Language},
  author={Yang, Kaiyu and Deng, Jia},
  journal={Transactions on Machine Learning Research (TMLR)},
  year={2023},
}

Requirements

  1. 1.3 <= Julia < nightly.
  2. Install the Julia packages in Project.toml: julia --project=. -e 'import Pkg; Pkg.instantiate()'.
  3. Install the Open-WBO MAX-SAT solver. This step is not necessary if you want to use only Z3. But some of our experiments use OpenWBO since it can be faster in certain cases.

Documentation

julia --project=. --color=yes docs/make.jl will build the documentation at docs/build/.

Training

Use scripts/train.jl for training. Datasets will be downloaded automatically. Run julia --project=. scripts/train.jl --help for command line options.

Experiments on MiniSCAN

julia --project=. scripts/train.jl --dataset MiniSCAN --weight-candidate 0.4 --weight-existing 0.3 --maxsat-solver Z3
