The PyPSDD Package is a python module for learning and reasoning with Probabilistic Sentential Decision Diagrams (PSDDs).
(This is a beta release: there are probably bugs.)
The PyPSDD Package can read in SDDs constructed by the SDD package:
http://reasoning.cs.ucla.edu/sdd
which is an open-source system (in the C language) for constructing and manipulating SDDs. Various wrappers are also available:
- PySDD (Python): https://github.com/wannesm/PySDD
- JSDD (Java): https://github.com/ML-KULeuven/JSDD
We suggest using the PyPy interpreter (https://pypy.org/) with the PyPSDD Package.

Sample code demonstrating how to use the PyPSDD Package can be found in pypsdd/tests/.
The PSDD was originally introduced in the paper:
"Probabilistic Sentential Decision Diagrams"
by Doga Kisa and Guy Van den Broeck and Arthur Choi and Adnan Darwiche
In Proceedings of the 14th International Conference on
Principles of Knowledge Representation and Reasoning (KR), 2014.

The PyPSDD Package was developed by Arthur Choi, of the Automated Reasoning Group at the University of California, Los Angeles.
