Course Introduction:The candidate elimination algorithm is a machine learning algorithm based on inductive reasoning that is used to learn a concept from given training data. Its purpose is to summarize all instances in the training data into the most general concept description, that is, the process of "concept learning". The basic idea of the candidate elimination algorithm is to initialize a most specific concept description and a most general concept description, and then gradually modify them until the most general concept description is finally obtained, that is, the desired concept. Specifically, the steps of the algorithm are as follows: 1. Initialize the most special concept description and the most general concept description: the most special concept description S0: initialize all attribute values to "?", indicating uncertainty; the most general concept description G0: All attribute values are initialized to "∅", indicating no
