srlearn

Introduction

srlearn is a project and set of packages for statistical relational artificial intelligence.

Standard machine learning tends to focus on learning and inference inside of a feature-vector (fit a model such that \(\boldsymbol{X}\) predicts \(y\)). Statistical Relational Learning attempts to generalize this to arbitrary graph and hypergraph data: where the prediction problem may include a set of objects with attributes and relations on those objects.

from srlearn.rdn import BoostedRDNClassifier
from srlearn import Background
from srlearn.datasets import load_toy_cancer
train, test = load_toy_cancer()
bk = Background(modes=train.modes)
clf = BoostedRDNClassifier(
    background=bk,
    target='cancer',
)
clf.fit(train)
clf.predict_proba(test)
# array([0.88079619, 0.88079619, 0.88079619, 0.3075821 , 0.3075821 ])
print(clf.classes_)
# array([1., 1., 1., 0., 0.])
