Genetically Generated Neural Networks I: Representational Effects

This paper studies several applications of genetic algorithms (GAs) within the neural networks field. After generating a robust GA engine, the system was used to generate neural network circuit architectures. This was accomplished by using the GA to determine the weights in a fully interconnected network. The importance of the internal genetic representation was shown by testing different approaches. The effects in speed of optimization of varying the constraints imposed upon the desired network were also studied. It was observed that relatively loose constraints provided results comparable to a fully constrained system. The type of neural network circuits generated were recurrent competitive fields as described by Grossberg (1982)

Genetically Generated Neural Networks II: Searching for an Optimal Representation

Genetic Algorithms (GAs) make use of an internal representation of a given system in order to perform optimization functions. The actual structural layout of this representation, called a genome, has a crucial impact on the outcome of the optimization process. The purpose of this paper is to study the effects of different internal representations in a GA, which generates neural networks. A second GA was used to optimize the genome structure. This structure produces an optimized system within a shorter time interval

The global crisis as a global opportunity : the Barcelona Consensus process = 全球危機作為全球機會 : 巴塞羅那共識

The global crisis demands global answers; answers that cannot come from those who provoked, accepted or took advantage of its causes. The world architecture built upon the ashes of the World War II is collapsing. The great foundations that granted America its hegemony, shared in part with all the other winners, 64 years later can no longer answer the necessities of a world undergoing deep transformations of various kinds. Neither Bretton Woods (America\u27s pillar in the economic-financial network in the IMF and the WB) nor the UN (political pillar in the Security Council) or the atom bomb(military pillar), which sealed the financial and political hegemony are acceptable any longer, and deep modifications must be considered. The global crisis is also a global opportunity to reconsider the questions and give voice to new answers. If one of the determining elements of the crisis has been the carelessness of politicians towards their responsibilities based on the belief that markets would regulate the necessities of common good, it cannot be that these same politicians will now manage the deep modifications that must be undertaken

Instructors Learn from Homework, too: Streamlining Data Collection to Facilitate Reteaching Before the Test

Whether it’s for accreditation or simply as a good teaching practice to inform future instruction, gathering and analyzing data can be time consuming. This is especially true for large classes. How can you streamline the process for quick evaluation?https://digitalscholarship.unlv.edu/btp_expo/1011/thumbnail.jp

Regularity, Local and Microlocal Analysis in Theories of Generalized Functions

We introduce a general context involving a presheaf A and a subpresheaf B of A. We show that all previously considered cases of local analysis of generalized functions (defined from duality or algebraic techniques) can be interpretated as the B-local analysis of sections of A. But the microlocal analysis of the sections of sheaves or presheaves under consideration is dissociated into a "frequential microlocal analysis " and into a "microlocal asymptotic analysis". The frequential microlocal analysis based on the Fourier transform leads to the study of propagation of singularities under only linear (including pseudodifferential) operators in the theories described here, but has been extended to some non linear cases in classical theories involving Sobolev techniques. The microlocal asymptotic analysis can inherit from the algebraic structure of B some good properties with respect to nonlinear operations

Fission products of superheavy elements. An investigation of the naturally occurring fission products of elements heavier than uranium

Fission mass yields in different structural elements and mineral separates were studied for the element X. The fission component for Pu-244, and the element X are discussed along with radiogenic Xe-129 and neutron activitation
