What Is Machine Learning?
Machine learning (ML) is the branch of AI where algorithms learn to make predictions or decisions by identifying patterns in data, rather than following hand-written rules. ML powers recommendation engines, fraud detection, demand forecasting, and most modern AI applications.
There are three main types of machine learning:
- Supervised learning — The model learns from labeled examples (e.g., "this email is spam, this one isn't")
- Unsupervised learning — The model finds hidden patterns in unlabeled data (e.g., customer segmentation)
- Reinforcement learning — The model learns by trial and error, optimizing for a reward signal
How Is Machine Learning Used in Business?
ML is the engine behind most business AI applications: predicting customer churn, optimizing pricing, detecting anomalies in financial data, and personalizing content. Unlike rule-based automation, ML systems improve as they process more data — creating compounding returns on investment. Businesses typically need digital twin engineering to identify which ML approaches match their data and objectives.
