Criticism
Critics of CBR argue that it is an approach that accepts anecdotal evidence as its main operating principle. Without statistically relevant data for backing and implicit generalization, there is no guarantee that the generalization is correct. However, all inductive reasoning where data is too scarce for statistical relevance is inherently based on anecdotal evidence. There is recent work that develops CBR within a statistical framework and formalizes case-based inference as a specific type of probabilistic inference; thus, it becomes possible to produce case-based predictions equipped with a certain level of confidence.

Famous quotes containing the word criticism:
“I, with other Americans, have perhaps unduly resented the stream of criticism of American life ... more particularly have I resented the sneers at Main Street. For I have known that in the cottages that lay behind the street rested the strength of our national character.”
—Herbert Hoover (18741964)
“In criticism I will be bold, and as sternly, absolutely just with friend and foe. From this purpose nothing shall turn me.”
—Edgar Allan Poe (18091845)
“A friend of mine spoke of books that are dedicated like this: To my wife, by whose helpful criticism ... and so on. He said the dedication should really read: To my wife. If it had not been for her continual criticism and persistent nagging doubt as to my ability, this book would have appeared in Harpers instead of The Hardware Age.”
—Brenda Ueland (18911985)
