Data Equivalence Class and Data Intelligent Separation-Discovery in Identification Algorithm

P-set is a set pair with dynamic characteristics, and ∧ type big data is a data equivalence class family composed of data equivalence classes with dynamic characteristics. By using the concept of equivalence class in algebra, we give new research on the mathematical characteristics of P-sets, ∧ type big data and identification algorithm, and obtain some new results in this paper. More precisely, we give the data equivalence class generation and attribute theorem, the data equivalence class separation intelligence, and applications of data equivalent separation-intelligent discovery and data intelligent retrieval.
