A python package for a distance-based classifier which can use several different distance metrics.

To install DistClassiPy, run the following command:

pip install distclassipy

Here's a quick example to get you started with DistClassiPy:

import distclassipy as dcpy
from sklearn.datasets import make_classification

X, y = make_classification(
    n_samples=1000,
    n_features=4,
    n_informative=2,
    n_redundant=0,
    random_state=0,
    shuffle=False,
)
clf = dcpy.DistanceMetricClassifier(metric="canberra")
clf.fit(X, y)
print(clf.predict([[0, 0, 0, 0]]))

• Distance Metric-Based Classification: Utilizes a variety of distance metrics for classification.
• Customizable for Scientific Goals: Allows fine-tuning based on scientific objectives by selecting appropriate distance metrics and features, enhancing both computational efficiency and model performance.
• Interpretable Results: Offers improved interpretability of classification outcomes by directly using distance metrics and feature importance, making it ideal for scientific applications.
• Efficient and Scalable: Demonstrates lower computational requirements compared to traditional methods like Random Forests, making it suitable for large datasets
• Open Source and Accessible: Available as an open-source Python package on PyPI, encouraging broad application in astronomy and beyond
