Scikit-learn is a powerful Python library for machine learning and data mining. It features various algorithms for supervised and unsupervised learning, and is widely used in the industry for its simplicity and efficiency.
Key Features
- Supervised Learning: Linear regression, logistic regression, support vector machines, decision trees, random forests, and many more.
- Unsupervised Learning: K-means clustering, hierarchical clustering, dimensionality reduction techniques like PCA, and anomaly detection.
- Preprocessing: Tools for feature extraction, feature selection, and data transformation.

Tutorials
Example
Here is a simple example of using Scikit-learn to perform linear regression:
from sklearn.linear_model import LinearRegression
# Create a linear regression object
regr = LinearRegression()
# Train the model using the training sets
regr.fit(X_train, y_train)
# Make predictions using the testing set
y_pred = regr.predict(X_test)
