döntésfa

Döntésfa is a Hungarian term that translates to "decision tree" in English. It is a fundamental concept used in various fields, including computer science, machine learning, statistics, and business decision-making. A decision tree is a graphical representation of a decision process and its possible consequences. It is structured like a tree, with a root node representing the initial decision or event.

From the root node, branches extend to represent the possible outcomes or choices. Each branch leads to another node, which can be either a decision node (requiring further choices) or a chance node (representing an uncertain outcome with associated probabilities). The tree continues to branch out until it reaches terminal nodes, also known as leaf nodes, which represent the final outcomes or decisions.

Decision trees are valuable tools for their ability to break down complex problems into simpler, manageable steps. They allow for the visualization of different scenarios and their potential results, aiding in the selection of the most favorable course of action. In machine learning, decision trees are used for both classification and regression tasks, forming the basis of more advanced algorithms like random forests and gradient boosting. The interpretability of decision trees makes them a popular choice for understanding the underlying logic of a model or decision-making process.
