Many studies on machine learning, and more specifically on regression, focus on the search for a precise model, when precise data are available. Therefore, it is well-known that the model thus found may not exactly describe the target concept, due to the existence of learning bias. In order to overcome the problem of too much illusionary precise models, this paper provides a general framework for...
The paper provides a discussion of the possibilistic regression method originally proposed by H. Tanaka. This method has the advantage of allowing the learning of an imprecise model, in the form of an interval-valued function. It may lead to an imprecise model even in presence of precise data, which is satisfactory from a learning point of view. Indeed, finding a precise model that perfectly represents...
