LASSO BBN

Learning Bayesian Belief Networks (BBNs) with LASSO. Example code is as below.

from lassobbn.learn import learn_parameters, learn_structure, to_bbn, to_join_tree, posteriors_to_df

# Step 1. Learn the structure
df_path = './data/data-binary.csv'
meta_path = './data/data-binary-complete.json'

parents = learn_structure(df_path, meta_path, n_way=2, ignore_neg_gt=-0.01, ignore_pos_lt=0.05)

# Step 2. Learn the parameters
d, g, p = learn_parameters(df_path, parents)

# Step 3. Get the BBN
bbn = to_bbn(d, g, p)

# Step 4. Get the Join Tree
jt = to_join_tree(bbn)

You can then use Py-BBN to create a BBN and join tree (JT) instance and perform exact inference.

Installation
