BN2O type networks 

At this web page we provide details about Bayesian networks of the BN2O type used in the experiments with arithmetic circuits described in the paper:
J. Vomlel and P. Savicky. Arithmetic circuits of the noisy-or models. In the Proceedings of the Fourth European Workshop on Probabilistic Graphical Models (PGM'08).
All networks and all results of the experiments from the paper may be downloaded below.

BN2O models

The name of the BN2O model in the form of bn2o-x-y-e-i
contains information about the BN2O structure:
For each x-y-e type x, y=10,20,30,40,50 and e/y=2,5,10,20, excluding those with e/y > x we generated randomly ten models (indexed by i=0,...,9). For every node from the bottom level we randomly selected e/y nodes from the top level as its parents.

Model formats

There are four files for each BN2O model in the tar file:
All BN2O models are in the XMLNET format of Ace 3.0.

Download

All models can be downloaded as one models-svetice.tar.gz file.

Complete results of experiments

For the experiments we used a development release of Ace, version 3.0.
Ace is a package that compiles a BN into an AC using one of
two available methods - c2d or the tabular compilation - see the Ace manual for details.
Since randomness is used during the Ace compilation process, Ace often provides different circuits for the same input model. Therefore for every model we performed ten experiments
five with c2d and five with the tabular method for both the original and the transformed models.

All lines of the result-x-y-e-i.txt files have the following format:

x y e i j o meth_o max_cluster_size_o t meth_t max_cluster_size_t


All results can be dowloaded as one results-svetice.tar.gz file.
