Introduction to Machine Learning - Class Notes
Machine learning is a subfield of artificial intelligence focused on building systems that learn from
data.
Supervised learning involves training a model on labeled data, while unsupervised learning uses
unlabeled data.
Key algorithms include linear regression, decision trees, support vector machines, and neural
networks.
Overfitting occurs when a model learns the training data too well and fails to generalize.
Cross-validation is a method used to evaluate the performance of a machine learning model.
Feature engineering is the process of selecting and transforming variables to improve model
performance.
Common tools include scikit-learn, TensorFlow, and PyTorch.
Ethical considerations include fairness, accountability, and transparency in AI systems.
