What are Random Forests

GlossaryMachine Learning

An ensemble method that combines many decision trees to improve prediction stability and accuracy.

Definition

Random Forests is an ensemble method that combines many decision trees to improve prediction stability and accuracy. In practical AI work, it helps teams connect a concept to data, model behavior, product choices, evaluation, and risk. The useful question is not only what the term means, but how it affects quality, cost, reliability, and decisions in a real workflow.

Example

A data scientist applies Random Forests while training, tuning, or evaluating a model on a real dataset.

Why it matters

Random Forests matters because an ensemble method that combines many decision trees to improve prediction stability and accuracy can change how teams build, evaluate, choose, or govern AI systems. It shapes how models learn from data, how performance is measured, and how teams decide whether a model is reliable enough.

How it works

Teams define the task, prepare data, choose a model or algorithm, train or tune it, evaluate metrics, and monitor results after deployment. For Random Forests, the key is to connect the definition with inputs, assumptions, measurable outcomes, and deployment limits.

Where it is used

  • Used in prediction, ranking, recommendation, classification, forecasting, optimization, and model evaluation.

Limitations

Results depend heavily on data quality, assumptions, metrics, distribution shifts, and the cost of mistakes.
