$ pip install data-complexityHow it works
Maximum Fisher's Discriminant Ratio (F1)
from dcm import dcm
from sklearn import datasets
iris = datasets.load_iris()
X = iris.data
y = iris.target
index, F1 = dcm.F1(X, y)Fraction of Borderline Points (N1)
from dcm import dcm
from sklearn import datasets
bc = datasets.load_breast_cancer(as_frame=True)
X = bc.data.values
y = bc.target.values
N1 = dcm.N1(X, y)Entropy of Class Proportions (C1) and Imbalance Ratio (C2)
from dcm import dcm
from sklearn import datasets

X = bc.data.values
y = bc.target.values
C1, C2 = dcm.C12(X, y)Other Measures
