Definition
Machine learning is a type of AI in which software learns patterns from past data and improves its predictions with experience, rather than following rules a programmer wrote by hand.[1]
At a glance
- Learns from examples in your data instead of being explicitly programmed for each rule.[1]
- Three main styles: supervised (labeled examples), unsupervised (find hidden groups), and reinforcement (learn by trial and reward).[2]
- Common business uses: fraud detection, customer segmentation, demand forecasting, and personalized recommendations.[3]
- Quality and quantity of training data largely determine how good the predictions are.
How it actually works
You feed the system many past examples, such as transactions labeled fraud or not-fraud. It detects statistical patterns and builds a model.[3] When new data arrives, the model predicts an outcome. Accuracy improves as it sees more data, mimicking how a person gets better with practice.[1]
Why it matters for your business
ML automates judgment-heavy tasks that are too varied for fixed rules, like spotting unusual spending or grouping customers. Surveys show most companies already use or plan to use it.[4] The payoff is efficiency and better decisions, but it depends on having clean, relevant data to learn from.
Bottom line
Machine learning turns your accumulated business data into a tool that predicts and decides, getting sharper the more good data it sees.
