Machine Learning Fundamentals

Explore hands-on tutorials and real-world applications of machine learning algorithms and concepts.

What is Machine Learning?

Machine Learning (ML) is a subset of artificial intelligence that enables systems to learn patterns from data and make decisions with minimal human intervention. Using statistical techniques, ML systems improve automatically through experience.

Example: A spam filter that improves its accuracy by analyzing patterns in incoming emails.

Core ML Concepts

Supervised Learning

Train models using labeled datasets with clear input-output pairs.

Unsupervised Learning

Discover hidden patterns in datasets without labeled outcomes.

Reinforcement Learning

Teach agents to make decisions based on trial-and-error with reward feedback.

Linear Regression

Understand how to make predictions using relationships between variables.

Neural Networks

Build and train models inspired by the human nervous system's structure.

Example: Linear Regression in Python


from sklearn.linear_model import LinearRegression
import numpy as np

# Sample data
X = np.array([[1], [2], [3]])
y = np.array([3, 5, 7])

# Create and train model
model = LinearRegression()
model.fit(X, y)

# Make prediction
print(model.predict([[4]]))  # Output: [9.0]

Sample code using scikit-learn to implement a basic linear regression model.
