High-Level Perception, Representation, and
... A given set of input data may be perceived in a number of different ways, depending on the context and the state of the perceiver. Due to this flexibility, it is a mistake to regard perception as a process that associates a fixed representation with a particular situation. Both contextual factors a ...

Compared to traditional binary sets (where variables only take on true or false values), fuzzy logic variables have a truth value that ranges in degree between 0 and 1. Fuzzy systems suggest a mathematic model to translate the real processes of human knowledge ( ...

Tolerance to Sound Intensity of Binaural
... All data were obtained with a “loose patch” technique, which permitted well isolated and stable extracellular recordings (Fig. 1). This is an important technical advance in the study of NL, because isolation of single neurons is very difficult to obtain, presumably because of the sparsely distribute ...
