In simpler terms pattern matching is the process of looking for a specific type of data within an expression One of the most commonly used patterns in AI is the instance pattern where a pattern is defined on the basis of an individual occurrence rather than a particular number of occurrences Another example is the regular expression pattern What is Pattern Matching in Artificial Intelligence Pickl AI. Pattern matching typically involves using regular expressions or other techniques to identify language constructs defined by the programming language being compiled such as function and variable Pattern matching always involves an attempt to link two patterns where one is a theoretical pattern and the other is an observed or operational one The top part of the figure shows the realm of theory The theory might originate from a formal tradition of theorizing might be the ideas or hunches of the investigator or might arise from
