TL;DR. A simple decision-making tool that uses a series of simple, sequential steps (like a tree) to make classifications.
Technical Definition
A simple decision-making tool that uses a series of simple, sequential steps (like a tree) to make classifications.
How it works
Fast-and-frugal trees are a type of decision tree designed for efficiency and ease of use in classification tasks. They employ a limited number of simple cues or features in a sequential manner, making decisions rapidly with minimal information. Their simplicity makes them effective in situations requiring quick judgments or when dealing with limited data.

- Classification — A supervised learning task where the model assigns inputs to discrete categories.
- Machine Learning — A field of AI where systems learn patterns from data instead of following hard-coded rules.
- Heuristics — Practical rules of thumb that produce good-enough solutions when optimal ones are too expensive.
- Decision tree — A decision tree is a supervised learning model that uses a tree-like structure of decisions and their possible consequences.
