rough set theory

Rough Set Theory is a mathematical approach to deal with uncertainty and incomplete information. It identifies classes of objects based on their properties, allowing us to analyze and categorize data without needing precise definitions. Essentially, it groups similar items together, even when there are gaps in information, helping in decision-making processes. For example, it can assist in identifying patterns in customer behavior or classifying diseases based on symptoms, making it useful in fields like data analysis, artificial intelligence, and decision support systems.
