基于BDI的Agent动态推理模型

本文基于慎思式Agem的理论,研究如何发展Agent的适应能力,对现有Agent的推理模型作了改进,提出了一个具有动态推理能力的Agem模型,在文章的最后用一个简单的事例验证了这种推理过程的合理性。     

广东妈租信仰及其流变初探

指出广东是最早传播妈祖信仰的地区之一。通过考察闽人入粤与妈祖信仰传入的关系,综述粤地各区妈祖宫庙的分布概况,分析妈祖信仰与南粤文化的融合,探讨其在粤地“被创造”的嬗变过程及特色。     

礼贤城隍庙：地方历史与区域文化的“记忆之所”

当传统在现代的冲击下与日常生活发生脱节时,人们往往通过保护一些过去留下的丈化遗产,试图留住传统,加固文化记忆。礼贤城隍庙原本是个民间宗教场所,但在它被列为当地的文物保护单位之后,这里也变成了一个当地人寄托怀古之情和确认文化身份的公共场所,也就是一个浓缩了当地历史和区域文化的“记忆之所”。复兴后的城隍庙会,也不再是纯粹的宗教性节日,而变成了一种带有象征性和表演性的当地文化资本。认识到城隍庙的这一功能演变,当事人及主管部门应抛开各种政治包袱,尽力去挖掘和恢复传统的民间信仰文化,让这些物质的和非物质的文化遗产能在新的文化语境中重放光彩。     

法律信仰论析

法治已成为现代社会文明的标志。而社会民众对法律的信仰是法治社会的基石。与西方发达国家相比,社会公众对法律信仰的缺乏,在一定程度上已经影响到了我国的法治化进程。究其原因主要是我国缺乏法律信仰的宗教土壤与法治的真正价值没有得以弘扬所致。因此,我们应当积极培育法律信仰的土壤,夯实法律信仰的根基,培养公众信仰法律的情感和信心。     

Seeking Allies: Modelling How Listeners Choose Their Musical Friends

In this paper we describe in some detail a formal computer model of inferential discourse based on a belief system. The key issue is that a logical model in a computer, based on rational sets, can usefully model a human situation based on irrational sets. The background of this work is explained elsewhere, as is the issue of rational and irrational sets (Billinge and Addis, in: Magnani and Dossena (eds.), Computing, philosophy and cognition, 2004; Stepney et al., Journey: Non-classical philosophy—socially sensitive computing in journeys non-classical computation: A grand challenge for computing research, 2004). The model is based on the Belief System (Addis and Gooding, Proceedings of the AISB’99 Symposium on Scientific Creativity, 1999) and it provides a mechanism for choosing queries based on a range of belief. We explain how it provides a way to update the belief based on query results, thus modelling others’ experience by inference. We also demonstrate that for the same internal experience, different models can be built for different actors.

影响林木种子贮藏的因素

为了每年提供造林新需的具有生活力的种子及长期保存种质资源,贮藏种子是必要的手段。种子寿命具有遗传性,且因树种而异。种子的贮藏特性可以分成5类:正常型、亚正常型、温带顽拗型、热带顽拗型和中间型。种子含水量和贮藏温度是影响种子贮藏是否成功的两个最重要因素。但因树种及其贮藏特性不同,种子含水量和贮藏温度的最适值也不同。为了保持正常型和亚正常型种子的生活力,这类种子必须密封贮藏;但对顽拗型种子,因其需要保持种子的代谢活性及要进行有氧呼吸,则需要气体交换。     

自主飞行器扩展态势评估方法研究

自主飞行器在高度不确定环境下执行复杂作战任务,必须同时兼顾任务完成、战略生存和飞行安全进行自主决策。行为能力等级定量反应了平台健康状态和生存、作战能力,是自主决策的前提和依据,战场威胁级别则反应了外部环境的影响。给出了扩展态势评估的定义,研究了基于贝叶斯网络与模糊逻辑的评估算法,建立了评估模型,构建了自主决策算法,依据扩展态势评估结果进行自主决策,仿真并分析了评估和决策结果,表明方法的有效性。     

The ecological rationality of explanatory reasoning

There is growing evidence that explanatory considerations influence how people change their degrees of belief in light of new information. Recent studies indicate that this influence is systematic and may result from people’s following a probabilistic update rule. While formally very similar to Bayes’ rule, the rule or rules people appear to follow are different from, and inconsistent with, that better-known update rule. This raises the question of the normative status of those updating procedures. Is the role explanation plays in people’s updating their degrees of belief a bias? Or are people right to update on the basis of explanatory considerations, in that this offers benefits that could not be had otherwise? Various philosophers have argued that any reasoning at deviance with Bayesian principles is to be rejected, and so explanatory reasoning, insofar as it deviates from Bayes’ rule, can only be fallacious. We challenge this claim by showing how the kind of explanation-based update rules to which people seem to adhere make it easier to strike the best balance between being fast learners and being accurate learners. Borrowing from the literature on ecological rationality, we argue that what counts as the best balance is intrinsically context-sensitive, and that a main advantage of explanatory update rules is that, unlike Bayes’ rule, they have an adjustable parameter which can be fine-tuned per context. The main methodology to be used is agent-based optimization, which also allows us to take an evolutionary perspective on explanatory reasoning.     

John Dewey's pragmatist alternative to the belief-acceptance dichotomy

Defenders of value-free science appeal to cognitive attitudes as part of a wedge strategy, to mark a distinction between science proper and the uses of science for decision-making, policy, etc. Distinctions between attitudes like belief and acceptance have played an important role in defending the value-free ideal. In this paper, I will explore John Dewey's pragmatist philosophy of science as an alternative to the philosophical framework the wedge strategy rests on. Dewey does draw significant and useful distinctions between different sorts of cognitive attitudes taken by inquirers, but none can be used to support the wedge strategy.
