%description
Case-based reasoning is a problem-solving methodology that involves
solving a new problem by referring to the solution of a similar problem in
a large set of previously solved problems. The key aspect of Case Based
Reasoning is to determine the problem that "most closely" matches the new
problem at hand. This is achieved by defining a family of distance
functions and using these distance functions as parameters for local
averaging regression estimates of the final result. The optimal distance
function is chosen based on a specific error measure used in regression
estimation. This approach allows for efficient problem-solving by
leveraging past experiences and adapting solutions from similar cases. The
underlying concept is inspired by the work of Dippon J. (2002)
<doi:10.1016/S0167-9473(02)00058-0>.
