Several applications are considered. In many areas of artificial intelligence, information

set of perceptual dimensions (naturalness, openness, roughness, expansion, ruggedness) that represent the dominant spatial structure of a scene. Then, we show that these dimensions may be reliably estimated using spectral and coarsely localized information. The model generates a multidimensional space

The tradeoff of spectral efficiency (b/s/Hz) versus energy -per-information bit is the key measure of channel capacity in the wideband power-limited regime. This paper finds the fundamental bandwidth--power tradeoff of a general class of channels in the wideband regime characterized by low

networks, and belief propagation. We establish direct connections between spectral and structural properties of complex networks and the speed of information diffusion of consensus algorithms. A brief introduction is provided on networked systems with nonlocal information flow that are considerably faster

Abstract Spectral information can be used for many CAD system tasks including synthesis, verification and test vector generation. AND/OR graphs are also useful for representing functions in CAD systems since they can offer advantages with respect to storage and representation of incompletely

Introduction Human hearing is concerned with the perception and interpretation of sensory input to the ears. Such perception may be classified as auditory events as opposed to sound events [5-1]. A sound event is the physical phenomenon of mechanical vibration which can characterize a sound source, while an auditory event is the brain's perception of an auditory phenomenon which may or may not be due to a sound event. The brain's auditory perception of the world around us is based on the cause-effect relationships that exist between most sound events and auditory events. The brain perceives sound sources by associating them with auditory events. Auditory function is carried out by the auditory system which culminates in the auditory cortex in the brain. 0y This work was supported by The Whitaker Foundation 2 CHAPTER 5.
