Expert systems

An expert system is a generic term meant to describe some sort of rule-based engine that’s been continuously refined and optimized over time. They were used heavily in the past in medical and legal use cases before ML became popularized. Although there are some companies that may still rely on them, their relevance has receded. They have a user interface (UI) and are powered by an inference engine that is connected to a knowledge base of some sort. It’s a more basic form of AI that’s made up of If Then statements. A rule-based engine means there are a set of pre-programmed instructions and algorithms that have been programmed into the backbone of how a product or system functions and there is an absence of self-learning. This means that ML models are not used and the system is not learning over time. Though this might sound like a dumb system, it’s still considered AI because it still might be functioning in a way that mimics how a human might...
