一种基于QPSO和WLS-SVM的智能方法

提出一种基于量子粒子群优化算法(QPSO)和加权最小二乘支持向量机(WLS-SVM)的智能方法,以克服常用方法存在需要较大样本数据量、建模速度较慢差等缺点.方法的具体改进是,将SVM中单一核函数构造成混合核函数,增加自适应权重,采用QPSO算法求解WLS-SVM训练模型中的线性方程组,这样能提高模型的性能.经过典型的二型糖尿病诊断实验,结果表明其建模速度快、诊断准确率高,其效果优于改进BP算法神经网络、LM算法神经网络和单核函数的SVM等方法.     

电容式位移传感器在气阀测试中的应用

电容式传感器具有结构简单、灵敏度高,动态特性好、对辐射和强烈振动等恶劣条件适应性强、价格便宜等一系列优点。但是,电容式传感器输出信号受干扰和温度影响较大、输出特性存在非线性等问题制约了电容式传感器的生产及应用。简述了自行研制的一种变距离电容位移传感器,以其在活塞式压缩机气阀运动规律测试中的应用为例,介绍了变距离电容位移传感器的设计原理和结构。同时采用单片机实现了输出信号的温度和非线性的软件补偿,并提出一种用正交多项式法来处理温度及非线性拟合曲线的数学方法,避免了采用最小二乘法解联立方程的繁琐过程,并可以任意增加逼近多项式的次数。在测量过程中实现了信号处理智能化。     

Concurrent Negotiation Model for Multi-agent-oriented Intelligence Reconnaissance System

In the multi-agent-oriented Intelligence Reconnaissance System （IRS）, there are a lot of negotiations in reconnaissance cost, reconnaissance quality and task among the reconnaissance platform agents. However, time the current negotiation models lack flexibility and can＇t meet the requirements of negotiations in the multi-agent-oriented IRS. To solve these problems, a concurrent negotiation model is presented in this paper, in which an auction is mapped into a one-to-many negotiation between seller and buyers. Thus, the mechanism and process of concurrent negotiations are studied. The results of simulation experiment show that this concurrent negotiation model has an advantage in achieving more and higher utility agreements than others, such as desperate and patient control models.     

Some historical remarks on Block’s “Aunt Bubbles” argument

The aim of this paper is to present a certain kind of argumentation against the idea of the Turing test (we call it CCSC—Complete Conversation System Claim) and to discuss the issue of its first formulation. Ned Block, with his idea of “Aunt Bubbles” argument, is thought of as a founding father of CCSC, but we present the results of our bibliographical researches which clearly show that the first formulation of CCSC should be ascribed to Polish writer and philosopher Stanisław Lem.

A simultaneous transit network design and frequency setting: Computing with bees

The transit network design problem belongs to the class of hard combinatorial optimization problem, whose optimal solution is not easy to find out. We consider in this paper the transit network design problem in a way that we simultaneously determine the links to be included in the transit network, assemble chosen links into bus routes, and determine bus frequency on each of the designed routes. Our approach to the transit network design problem is based on the Bee Colony Optimization (BCO) metaheuristic. The BCO algorithm is a stochastic, random-search technique that belongs to the class of population-based algorithms. This technique uses a similarity among the way in which bees in nature look for food, and the way in which optimization algorithms search for an optimum of a combinatorial optimization problem. The numerical experiments are performed on known benchmark problems. We clearly show that our approach, based on the BCO algorithm is competitive with the other approaches in the literature and that can generate high-quality solutions.

Effects of partialing out postmorbid WAIS scores in a heterogenous sample: Comment on Golden et al.

This comment addresses recent concerns about the effects of partialing out postmorbid Wechsler Adult Intelligence Scale (WAIS) scores from the relationship between the Luria-Nebraska (LNNB) and the Halstead-Reitan (HRB) neuropsychological batteries. Such concerns are valid only when attempting to examine the sensitivity of the two batteries to discriminate between diagnostic groups. However, when knowledge of group membership is lost by collapsing data across diagnostic groups, it is not possible to attribute variance to specific factors such as the presence or degree of brain dysfunction. In such a design, partialing of the WAIS does not "correct" for brain damage but reflects the degree of association across groups between the LNNB and HRB independent of their common overlap with the WAIS. Independent of the WAIS, the data indicate that the two batteries are not "equivalent," and appear to assess different ranges of behavioral variability. This difference is not necessarily negative and may have positive implications for the practice of neuropsychology. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
