Credici: Credal Inference for Causal Inference

Credici is an open-source library that allows to use credal inference methods for causal analysis:

public class EquationlessFromFile {
    public static void main(String[] args) throws IOException, InterruptedException {

        // Load the empirical model
        String fileName = "./models/simple-bayes.uai";
        BayesianNetwork bnet = (BayesianNetwork) IO.read(fileName);

        // Get the markovian equationless SCM
        StructuralCausalModel causalModel = StructuralCausalModel.of(bnet);

        // Set query
        TIntIntMap intervention = new TIntIntHashMap();
        intervention.put(0,1);
        int target = 1;


        // Approx inference
        CredalCausalAproxLP inf = new CredalCausalAproxLP(causalModel, bnet.getFactors());
        IntervalFactor res = inf.doQuery(target, intervention);
        System.out.println(res);

        //Exact inference
        CredalCausalVE inf2 = new CredalCausalVE(causalModel, bnet.getFactors());
        VertexFactor res2 = inf2.doQuery(target, intervention);
        System.out.println(res2);
