Stochastic Gradient Trees implementation in Python

Overview

Stochastic Gradient Trees - Python

Stochastic Gradient Trees1 by Henry Gouk, Bernhard Pfahringer, and Eibe Frank implementation in Python. Based on the parer's accompanied repository code.

Python Version 3.7 or later

Used Python libraries:

  • numpy>=1.20.2
  • scipy>=1.6.2
  • pandas>=1.3.3
  • scikit-learn>=0.24.2

Usage:

    from StochasticGradientTree import StochasticGradientTreeClassifier

    from sklearn.model_selection import train_test_split
    from sklearn.datasets import load_breast_cancer
    from sklearn.metrics import confusion_matrix, accuracy_score, log_loss

    def train(X, y):

        X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.34)
        
        tree = StochasticGradientTreeClassifier()

        tree.fit(X_train, y_train)
    
        y_pred = tree.predict(X_test)

        proba = tree.predict_proba(X_test)        

        acc_test = accuracy_score(y_test, y_pred)
        print(confusion_matrix(y_test, y_pred))
        print('Acc test: ', acc_test)
        print('Cross entropy loss: ', log_loss(y_test, proba))

        return tree, acc_test

    if __name__ == "__main__":

        breast = load_breast_cancer(as_frame=True)

        X = breast.frame.copy()
        y = breast.frame.target
        
        X.drop(['target'], axis=1, inplace=True) 

        tree, _ = train(X, y)

Binary classification example:

python classification_breast.py

Multiclass classification (using the One-vs-the-rest multiclass strategy):

python classification_iris.py

Regression example:

python regression_diabetes.py
