Although most classifications place all hagfishes in the family Myxinidae, they are sometimes divided into two families: Myxinidae, represented in every ocean, and Eptatretidae, represented everywhere but the North Atlantic.
In most classifications, the major criterion is a combination of suggestive clinical symptoms after exposure to antigens, HRCT abnormalities, specific serum antibodies and lymphocytosis on BAL.
Most classification attempts in the literature have been intuitive and empty of justification.
Thus, we did found that for most classification algorithms in the datasets we considered, using discretization alone was less effective than using the original features.
We considered alternative approaches to model development including classification and regression tress (CART) and neural networks, but neither of these approaches has been consistently shown to outperform logistic regression for most classification problems in medicine [ 29- 31].
Most classification categories contained in the DSM-IV and ICD-10 were derived from psychopathology in adults, adolescents, and school-age children.
In particular, the most prominent classifications in both sets of results are largely analogous, namely philosophical-based research, and theory-based contributions.
In practice, regular attributes and criteria coexist in most classification tasks.
However, the large number of PolSAR parameters and discriminators cannot all be used in most classification problems.
Most classification algorithms are "passive", in that they assign a class label to each instance based only on the description given, even if that description is incomplete.
