python-scikit-learnUsing LDA classifier example


from sklearn import datasets, discriminant_analysis, model_selection

X, y = datasets.load_iris(return_X_y=True)
X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y)

model = discriminant_analysis.LinearDiscriminantAnalysis()
model.fit(X_train, y_train)
y_pred = model.predict(X_test)ctrl + c
from sklearn import

import module from scikit-learn

load_iris

loads Iris dataset

model_selection.train_test_split

splits given X and y datasets to test (25% of values by default) and train (75% of values by default) subsets

.LinearDiscriminantAnalysis(

creates LDA model

.fit(

train transformation model

.predict(

predict target variable based on given features dataset


Usage example

from sklearn import datasets, discriminant_analysis, model_selection

X, y = datasets.load_iris(return_X_y=True)
X_train, X_test, y_train, y_test = model_selection.train_test_split(X, y)

model = discriminant_analysis.LinearDiscriminantAnalysis()
model.fit(X_train, y_train)

print(model.score(X_test, y_test))
output
