gen-bn

Generates random probabilistic networks with Bernoulli random variables.

Requirements

Python 3, numpy, (optional) networkx, matplotlib

See

./gen-bn --help

for information on parameters to the generator.

The network is written by default to bn.json, with the following format:

{
  <node_id>: {
    "parents": [...]
    "prob": [
       [<assignment>, <probability>]
       ...
    ]
  },
  ...
}

where:

<node_id> is the numeric identifier for a variable.
parents has a list of variables that <node_id> depends on.
prob has a list of conditional probabilities such that P(<node_id>=1|<parents>=<assignment>)=<probability>. In other words, it has the list of probabilities of success for the Bernoulli random variable based on every configuration of its parents.
