highfis 0.2.0

highFIS is a comprehensive Python package for training and evaluating high-dimensional TSK fuzzy systems, built on PyTorch and compatible with the scikit-learn API.

highFIS

Python library for high-dimensional Takagi–Sugeno–Kang (TSK) fuzzy inference systems, built on PyTorch with a scikit-learn compatible API.

📦 Installation

Install from PyPI:

pip install highfis

🧠 Quick Start

from highfis import HTSKClassifierEstimator

clf = HTSKClassifierEstimator(
    n_mfs=3,
    rule_base="en",
    epochs=200,
    learning_rate=1e-3,
    ur_weight=0.01,
    random_state=42,
)
clf.fit(X_train, y_train)
print(clf.score(X_test, y_test))

Works with sklearn.pipeline.Pipeline, GridSearchCV, and cross_val_score.
