What are the four concepts of learning?
Klausmeier (1974) suggests four levels of concept learning: (1) concrete – recall of critical attributes , (2) identity – recall of examples, (3) classification – generalizing to new examples, and (4) formalization – discriminating new instances.
What are the types of concepts?
A concept is a way to classify the world in your mind. The hierarchical model of concept classification includes three levels of concept: the most general is the superordinate concept, followed by the basic concept , and the most specific is the subordinate concept.
What is machine learning what are key tasks of machine learning?
A machine learning task is the type of prediction or inference being made, based on the problem or question that is being asked, and the available data . For example, the classification task assigns data to categories, and the clustering task groups data according to similarity.
What is machine in machine learning?
