Code Examples

Getting Started with scikit-learn

import sklearn
from sklearn.datasets import load_iris
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier

data = load_iris()
X_train, X_test, y_train, y_test = train_test_split(data.data, data.target, test_size=0.3)

model = RandomForestClassifier()
model.fit(X_train, y_train)
print('Model accuracy:', model.score(X_test, y_test))

Advanced scikit-learn Example

from sklearn.pipeline import Pipeline
from sklearn.preprocessing import StandardScaler
from sklearn.svm import SVC

pipeline = Pipeline([
    ('scaler', StandardScaler()),
    ('svc', SVC(kernel='linear'))
])

pipeline.fit(X_train, y_train)
print('Pipeline accuracy:', pipeline.score(X_test, y_test))

Alternatives

TensorFlow PyTorch

Common Methods

fit

Trains the model using the training data.

score

Evaluates the model's accuracy on the test data.
