A model of auditory temporal reca l l based on correlographic recording and Interrogation by convolution is presented. Complex tree and loop structured memory sequences can be recorded, with selective reca l l based on fragmentary cues. The sequences are " re membered" by proceeding through a recorded net of associations u n t i l the coherence of the retr ieved signals f a l l s to a su f f i ...

We st udy the perfor mance of a neural network of the percept ron typ e. We isolate two important set s of pa rameters which render t he network fault tolerant (existence of large basins of attraction) in both hetero-associat ive and auto-associative systems and study t he size of the bas ins of attraction (the maximal allowable noise level st ill ensuring recognition ) for sets of random patte...

The medieval eschatological tradition of the ‘15 Signs of the Last Days’ pays special attention to the anguish of animals. This attention seems unnecessary, as animals will not be judged, or resurrected, but only destroyed. Their unnecessary cries might be heard as the cry of life for itself, now useless to God and humans, and also as a reminder to humans of the richness of the worlded selves t...

1 I n t r o d u c t i o n Schema-based Natural Language Generation (NLG) systems, e.g., [Weiner, 1980; McKeown, 1985; Paris, 1988], determine the information to be presented based on common patterns of discourse. Goal-based planners, e.g., [Moore and Swartout, 1989; Cawsey, 1990], select a discourse operator if its prescribed effect matches a given communicative goal. If there is more than one ...

The fractional integrals I+(x)0 of variable order e(x) are considered. A theorem on mapping properties of Ia+ in Holder-type spaces H is proved, this being a generalization of the well known Hardy-Li ttlewood theorem.

The paper sets up a conceptua I framework for constructing knowledge-based, computer-aided environments for system design. The framework is based on the formal structures underlying the expert system design methodology being developed by Zeigler [18], name 1 y that of the system entity structure and experimental frame. The system entity formalism is emp I oyed to structure the family of design ...
