Neural Pattern Recognition With Multi-Scale Pyramidal Coding and Selective Attention

A new neural network architecture for spatial patttern recognition using multi-scale pyramida1 coding is here described. The network has an ARTMAP structure with a new class of ART-module, called Hybrid ART-module, as its front-end processor. Hybrid ART-module, which has processing modules corresponding to each scale channel of multi-scale pyramid, employs channels of finer scales only if it is necesssary to discriminate a pattern from others. This process is effected by serial match tracking. Also the parallel match tracking is used to select the spatial location having most salient feature and limit its attention to that part.Sharp Corporatio

Neural Pattern Recognition on Multichannel Input Representation

This article presents a new neural pattern recognition architecture on multichannel data representation. The architecture emploies generalized ART modules as building blocks to construct a supervised learning system generating recognition codes on channels dynamically selected in context using serial and parallel match trackings led by inter-ART vigilance signals.Sharp Corporation, Information Techology Research Laboratories, Nara, Japa

Standards as a platform for innovation and learning in the global economy: a case study of Chilean salmon farming industry

Conventionally, standards are considered as a governance tool in the production system in a one-directional and hierarchical relationship between foreign trans-national corporations (TNCs) or global buyers on one hand and subsidiaries and producers on the other. They were considered as transmitting necessary specifications of goods (codified knowledge) to the producers. Despite the fact that this process begins with a one-way power relationship and associated flow of knowledge and standards, such one-way flows may become consolidated into two-way interlinkages when power balances themselves reverse with the development of collective capability in catching-up countries. In such a context, standards increasingly act as a catalyst for creating collective interfaces where diverse knowledge from horizontal and vertical relationships (local and global, tacit and codified, and buyer and producer) intercept and converge to promote interactions and learning for those involved. The Chilean salmon farming industry is examined to understand how standards compliance enhanced collective capability.Standards, Industrial standards, Capability, Governance, Fishing industry, Chile, Catching up

Numerical calculation of tensile test using a dumbbell-shaped in thickness direction specimen

This study is the product of a tensile test of a uniaxial tensile specimen having a thinner test section than parallel section, which is a tensile test piece with a dumbbell shape in the thickness direction, fabricated by means of cutting as a preliminary experiment and an evaluation of the mechanical properties of the tensile specimen. In the tensile test, we compared the tensile properties of the dumbbell-shaped in thickness direction tensile specimen with those of conventional tensile specimens. In addition, we analyzed the states of stress and strain in the tensile specimens during a tensile test by using the finite element method

On the Mutual Information in Hawking Radiation

We compute the mutual information of two Hawking particles emitted consecutively by an evaporating black hole. Following Page, we find that the mutual information is of order exp(-S) where S is the entropy of the black hole. We speculate on implications for black hole unitarity, in particular on a possible failure of locality at large distances.Comment: 4 pages, LaTeX, 1 figur
