Taxonomies have been proposed numerous times in the literature in order to encode semantic relationships between classes. Such taxonomies have been used to improve classification results by increasing the statistical efficiency of learning, as similarities between classes can be used to increase the amount of relevant data during training. In this paper, we show how data-derived taxonomies may ...

T HE CURRENT STUDY was suggested by the observation that various substances are capable of potentiating the inotropic response of the papillary muscle to epinephrine. The object of the study has been to obtain information about the nature of the action by which such substances as cysteine, cystine, tyrosine, ascorbic acid, and plasma are capable of producing this potentiation. Four possible sit...
