The problem considered in this chapter is how to assess different perceptions of changing socio-technical conflicts. Our approach to the solution to this problem of assessing conflict dynamics is to consider negotiation views within the context of perceptual information systems. Briefly, perceptual information systems (succinctly, perceptual systems) are real-valued, total, deterministic inform...

Two approaches to the study of musical sound timbre are described and documented by psychoacoustic experiment examples. The classical bottom-up approach is demonstrated on the study of contexts of violin sounds and pipe organ sounds. Verbal attributes collected during listening tests were used for the interpretation and comparison of resulted perceptual spaces of sounds. The proposed top-down a...

Perceptual categorization is a key problem for an agent to cope with its internal and external world. Following a functional and subjective approach of cognitive modeling, the primary purpose of perceptual categorization is modeled as the valuation of a stimulus regarding its potential to satisfy an agent's current needs. Additionally an integrated and holistic approach is used, where categoriz...

Source separation evaluation is typically a top-down process, starting with perceptual measures which capture fitness-for-purpose and followed by attempts to find physical (objective) measures that are predictive of the perceptual measures. In this paper, we take a contrasting bottom-up approach. We begin with the physical measures provided by the Blind Source Separation Evaluation Toolkit (BSS...

The use of ℓ p (p = 1,2) norms has largely dominated the measurement loss in neural networks due to their simplicity and analytical properties. However, when used assess visual information, these simple are not very consistent with human perception. Here, we describe a different “proximal” appro...

The limitations of graphical user interfaces have slowed the spread of computer usage to the entire population. Perceptual user interfaces are one approach that can overcome many of these limitations. Adding perceptual capabilities, such as speech, sketching, and vision, is the key to making interfaces more effective. We argue that informal user interfaces, which do little or no up-front recogn...
