03 Dec 1996TL;DR: Some innovations in the training and use of ANNs as character classifiers for word recognition, including normalized output error, frequency balancing, error emphasis, negative training, and stroke warping are presented.
Abstract: We have combined an artificial neural network (ANN) character classifier with context-driven search over character segmentation, word segmentation, and word recognition hypotheses to provide robust recognition of hand-printed English text in new models of Apple Computer's Newton Message Pad. We present some innovations in the training and use of ANNs as character classifiers for word recognition, including normalized output error, frequency balancing, error emphasis, negative training, and stroke warping. A recurring theme of reducing a priori biases emerges and is discussed.

TL;DR: The results show that when an object possesses the appropriate concrete features, but does not fulfill the appropriate abstract value, it is judged to be a category member in one sense but not in another, suggesting a normative dimension in everyday conceptual representation.

TL;DR: In this paper, it was shown that every irreducible (complex) character of U n (q) is a constituent of a unique basic character, which was proved under the assumption p > n, where p is the characteristic of the field F q with q elements.
Abstract: Let U n (q) denote the (upper) unitriangular group of degree n over the finite field F q with q elements. In this paper we consider the basic (complex) characters of U n (q) and we prove that every irreducible (complex) character of U n (q) is a constituent of a unique basic character. This result, extends a previous result which was proved by the author under the assumption p > n, where p is the characteristic of the field Fq.

TL;DR: This paper found that language is a feature to distinguish the human from the animal that has seemed a more enduring diagnostic character than some. But how is the breath of words to be made visible in the stony traces of the Pleistocene?
Abstract: Language is a feature to distinguish the ‘human’ from the ‘animal’ that has seemed a more enduring diagnostic character than some. But how is the breath of words to be made visible in the stony traces of the Pleistocene?
