Description: Rule-Based Systems are artificial intelligence tools that use a set of predefined rules to process information and make decisions. These rules, which can be simple or complex, are established based on expert knowledge in a specific domain. The main characteristic of these systems is their ability to identify patterns and anomalies in data, making them particularly useful for detecting unusual behaviors or deviations from the norm. By operating under a logical framework, rule-based systems can provide clear explanations for their decisions, facilitating the interpretation of results. Their relevance lies in their applicability across various fields, such as artificial intelligence, data analysis, and operational management, where early identification of anomalies can prevent larger issues. Additionally, their modular structure allows for the updating and adaptation of rules as new knowledge is acquired or new challenges arise, making them a flexible and effective tool in various technological contexts.
