An automatic feature generation method for handwritten digit recognition is described. Two different evaluation measures, orthogonality and information, are used to guide the search for features. The features are used in a backpropagation trained neural network. Classification rates compare favorably with results published in a survey of high-performance handwritten digit recognition systems. T...

A δ-uniform BSS machine is a standard BSS machine which does not rely on exact equality tests. We prove that, for any real closed archimedean field R, a set is δ-uniformly semi-decidable iff it is open and semi-decidable by a BSS machine which is locally time bounded; we also prove that the local time bound condition is nontrivial. This entails a number of results about BSS machines, in particu...

Case presentation 1: Mr F. is a 60-year-old man with unstable angina who takes aspirin, 81 mg/day. A platelet function test demonstrates that his platelets are “resistant” to aspirin. Should his treatment be changed? Case presentation 2: Mr K. is a 60year-old man with unstable angina who takes aspirin, 81 mg/day, and clopidogrel, 75 mg/day. A platelet function test demonstrates that his platele...

The authors investigated the cue dependency of source and item memory. Individuals listened to words spoken by a man or a woman and later determined whether a test word was previously presented by a man or by a woman, or whether it was a new word. Cue dependent effects were assessed by presenting test words with (a) the same voice (match condition) that originally presented the word, (b) a diff...
