Extending the participatory learning paradigm to include source credibility

We provide an overview of the participatory learning paradigm (PLP) and discuss the importance of the acceptance function in determining which observations are used for learning. We introduce a formal model that uses this (PLP) We then extend this model in two directions. First, we consider situations in which we have incomplete observations, we only have observations about a subset of the variables of interest. Next we extend this model to allow for the inclusion in the learning process of information about the learning agents belief about the credibility of the source of the learning experience. Here we distinguish between the content of a learning experience and the source of the experience. We provide a means to allow the learning agents belief about the credibility of the source to determine the effect of the content. Furthermore we suggest a method to allow the modification of agents belief about the credibility of the source to also be part of the learning process.     

分光光度法用于研究固色剂对活性染料染色单板耐水色牢度的影响

采用高固色率的双活性基M型活性染料对速生人工林木材进行染色,均有很好的易染性和渗透性以及较高的上染率。利用不同种类固色剂对活性染料染色单板进行处理,利用分光光度法,分别测定未经和经固色剂处理的活性染料染色单板热水浸泡液的分光光度值,可知分别经3种环保型固色剂处理后的活性染料染色单板的耐水色牢度均有不同程度的提高,其中以NRT处理过的染色单板的耐水色牢度最佳。

一种基于 Agent 劝说分类的让步模型及实现

随着电子商务的迅速发展以及Agent理论和方法的引入,出现了关于Agent自动谈判等方面的研究。 A-gent劝说由于能节约商务谈判成本,提高商务谈判效率,使谈判过程更加理性,解决谈判中出现的许多问题,受到了广泛的关注。本文结合人际劝说理论,对Agent劝说进行了分类;结合形式化理论,构建了相应的形式化表述模型和交互机制;然后将两者相结合,在让步影响幅度的基础上,构建了基于Agent劝说分类的让步模型;最后,通过算例和系统实现对模型的可行性、有效性进行了验证。     

Cr(VI)吸附剂及其吸附机理研究进展

摘要 重金属污染已成为影响人们生活亟亟待解的问题,它不仅威胁着自然环境的持续发展,更是对人类身体健康提出了严峻的考验。其中,六价铬因为环境污染持续久,危害大,更是得到各国研究者的重视。研究者们研究了各种吸附材料,它们对于六价铬的移除能力以及移除机理不尽相同。本文介绍了Cr(VI)吸附材料分类及其特点,重点分析了聚合物吸附材料在吸附和分离Cr(VI)方面的应用进展。并简要介绍了Cr(VI)吸附过程中的吸附动力学模型和等温方程式,以著名的Langmuir和Freundlich模型为例加以说明,为解决重金属铬离子引起的环境污染尤其水污染问题提供一种借鉴。     

Agent‐based computational models and generative social science

This article argues that the agent‐based computational model permits a distinctive approach to social science for which the term “generative” is suitable. In defending this terminology, features distinguishing the approach from both “inductive” and “deductive” science are given. Then, the following specific contributions to social science are discussed: The agent‐based computational model is a new tool for empirical research. It offers a natural environment for the study of connectionist phenomena in social science. Agent‐based modeling provides a powerful way to address certain enduring—and especially interdisciplinary—questions. It allows one to subject certain core theories—such as neoclassical microeconomics—to important types of stress (e.g., the effect of evolving preferences). It permits one to study how rules of individual behavior give rise—or “map up”—to macroscopic regularities and organizations. In turn, one can employ laboratory behavioral research findings to select among competing agent‐based (“bottom up”) models. The agent‐based approach may well have the important effect of decoupling individual rationality from macroscopic equilibrium and of separating decision science from social science more generally. Agent‐based modeling offers powerful new forms of hybrid theoretical‐computational work; these are particularly relevant to the study of non‐equilibrium systems. The agent‐based approach invites the interpretation of society as a distributed computational device, and in turn the interpretation of social dynamics as a type of computation. This interpretation raises important foundational issues in social science—some related to intractability, and some to undecidability proper. Finally, since “emergence” figures prominently in this literature, I take up the connection between agent‐based modeling and classical emergentism, criticizing the latter and arguing that the two are incompatible. © 1999 John Wiley & Sons, Inc.     

江门市2004年-2006年腊味中色素监测结果分析

对江门市2004-2006年腊味在色素进行监测,并对色素使用情况进行评估.在市区各农贸市场及各大超市,各腊味制品工厂和加工场抽取126份样品,进行检验,被检样品中发现46份违规添加色素,其中有部分是胭脂红,有部分是苋菜红,少量是柠檬黄,并且有部分样品添加非食用色素-苏丹红.江门市腊味中色素使用情况经过整顿已经明显改观,但仍有必要加强有关的监测和溯源分析.     

一种面向Agent的智能大系统

从Ａgent理论出发,构造了一种面向Agent的智能大系统。系统由一个协调控制子系统的多个Ａgent组成的多Agent系统;协调控制子系统为系统的全局数据库和监控、协调、优化中心。Ａgent之间的协作有任务分担和结果共享两种方式,它们之间的冲突是通过多轮协商法来解决的。大系统的优化、控制就是通过上述多Ａgent系统实施,以达到对大系统进行动态优化,控制和模型的自适应的目的。
