What is machine learning? Machine learning: Machines learn to predict outcomes from data without being explicitly programmed.

Types of machine learning Three types:  Supervised, unsupervised, and reinforcement learning.

Applications of machine learning Fraud detection, medical diagnosis, product recommendation, natural language processing, and image recognition.

Benefits of machine learning Accuracy, scalability, automation, and decision making.

Challenges of machine learning Data requirements, overfitting, bias, and interpretability.
