What Is Machine Learning and Why It Matters for Business
Machine Learning (ML) is the branch of artificial intelligence that enables computers to learn from data and make predictions without being explicitly programmed for each scenario.
Difference from traditional programming:
- Traditional programming: Rules + Data = Result
- Machine Learning: Data + Results = Rules (the model learns by itself)

Relevant ML Statistics in Business
Types of Machine Learning
1. Supervised Learning
The model learns from labeled examples.
Business applications:
Concrete example:
You have data about 10,000 customers - some have left (churned), others have stayed. The model learns what characteristics churned customers have and can predict which current customers are at risk.
2. Unsupervised Learning
The model discovers patterns in data without labels.
Business applications:
Concrete example:
You give the model data about customer purchasing behavior. It identifies on its own 5 distinct customer segments you didn't know about - for example "occasional weekend buyers" or "price-sensitive loyalists".
3. Reinforcement Learning
The model learns through trial and error, receiving rewards for correct actions.
Business applications:
