Empirical Christoffel function for outlier detection

Empirical Christoffel function for outlier detection

This module is an implementation of the empirical Christoffel function applied to outlier detection as proposed by Lasserre and Pauwels in The empirical Christoffel function with applications in data analysis.

Example

from ecf import EmpiricalChristoffelFunction
import numpy as np

# Initialize the detector with default degree (4)
c = EmpiricalChristoffelFunction()

# Generate random data points
X = np.array([[0,2],[1,1.5],[0.2,1.9],[100,1.2]])

# Predict the outliers
print(c.fit_predict(X))

# Print the scores
print(c.score_)
