....errors. He may also, mistakenly, consider some information to be irrelevant or redundant, or alternatively, make things unnecessarily complicated. An alternative to conventional systems of determining parameters, based on supervised learning of discriminating or structural descriptions [24 33], is the use of techniques based on unsupervised learning of taxonomic descriptions [34 41] more suitable on the other hand to be applied to ill structured domains (see [42] for an overview and extensive bibliography on inductive learning methods) When an expert rationalizes about his ....

....problem p. After that, the new description D = D (f=v) has a smaller discriminatory set S D formed by those cases subsumed by D . Thus, specialization reduces the discriminatory set S D S D at each step. As we explain below, LID uses a heuristic measure based on the Lpez de Mntaras distance [6] to determine the feature to be added. LID specializes D by selecting one feature f from all the features used in p in the following way. Each feature f i in p induces a partition P i = S i1 . S in in the set S D such that each S ik P i contains those patients in S D having the same value v ....

....P c , that divides S D according to the risk (R i R) for the complication C. In the example, S D is divided in subsets according to the values for the risk of stroke being unknown, low, moderate, high, and very high. For each partition P i , LID computes the Lpez de Mntaras (RLM) distance [6] to the correct partition P c . Intuitively, the RLM distance assesses how similar a partition is with respect to a referent partition (i.e. the correct partition) in the sense that the lesser the distance the more similar they are. The RLM distance was introduced as an alternative to the ....
