The formation of notions usually relies on a database or provided examples, alternating with verbal statements. The collection of data / examples presented in a lesson can be considered a sample u from U. In this context, by objects we understand actions, examples, events, etc. Objects are vectors of features (notes) or attributes. A feature is considered to be a dimension from whose point of view objects can have common parts or differ from each other (by size, shape, colour, destination, etc.).
Key words: notion, conception, definition, the judgment, the reason
