STEP (Symbolic and Tractable Explanation Package)

Generates explanations from a Sentential Decision Diagram (SDD). The explanation techniques are described in the following paper:

A Symbolic Approach to Explaining Bayesian Network
In Proceedings of the 27th International Joint Conference on Artificial Intelligence (IJCAI), 2018.
Andy Shih and Arthur Choi and Adnan Darwiche.

Input Format

The input SDD is specified using "config.json". It should have a JSON object with the following fields:

  • "name": the name of the SDD of interest
  • "sdd_filename": the filepath for the SDD
  • "vtree_filename": the filepath for the vtree accompanying the SDD
  • "variable_description_filename": the filepath of the variable description file for the SDD

First, each occurrence of %s in the configuration paths will be replaced with config["name"]. Then, the SDD file should be located at config["sdd_filename"], the vtree file should be located at config["vtree_filename"], the variable description file should be located at config["variable_description_filename"].

For example, if config["name"] = "admission_1" and config["sdd_filename"] = "sdd/%s/%s.sdd" then the SDD file should be located at "sdd/admission_1/admission_1.sdd".

Output Format

The explanation output will be printed to stdout.

Running BNC_SDD

Edit src/expl.py to play around with the different explanation queries available in src/explanation_queies.py.

Then, run

./run
