有限理性模型在游戏智能决策中的研究与应用*

为了让游戏NPC能够学习和模拟玩家在游戏中的策略和行为方式,在基于模型的智能决策方法基础上,结合行为决策理论中的有限理性模型提出了一种新的游戏智能方法.该方法分别从有限理性模型的两个核心原则——有限理性和满意准则来改进过去的方法在感知和决策过程中所面对的问题,从而使得游戏NPC行为决策方式更加人性化.最后,通过在Starcraft平台上与其他方法的对抗性实验来进一步验证该方法的优势.     

游戏数据的可视分析

随着在线网络游戏的盛行以及相应游戏环境的复杂化和游戏玩家数量的增多,利用海量玩家行为数据来理解分析玩家行为和评估游戏表现越来越受到重视.为了使得成千上万的游戏数据能够被直观有效地理解,研究人员尝试使用了相应的可视分析方法和技术.文中主要考虑游戏开发者的任务,从游戏表现评估和玩家行为分析两大方向出发,总结并探讨了完成这些任务的可视化文献以及相应的可视化技术进展和挑战,并提出对解决这些任务的可视化工具和技术的展望.     

文案策划小论（下）

RPG游戏本质上是游戏玩家融入所扮演的角色和游戏世界的过程，游戏的扮演观就是对玩家如何融入自己扮演的游戏角色的看法，而MMORPG则更多的是以实现自我为主的角色扮演，它可不以需要剧情来实现游戏体验，所以MMORPG中的角色是现实世界中的玩家在游戏的虚拟世界中的延伸，     

基于元胞自动机的模糊控制换道模型

根据元胞自动机理论建立改进的交通流模型,给出每辆车的演化规则。在此基础上依据实际车辆行为建立换道规则,利用模糊推理来模拟人在换道过程中的主观判断过程,建立换道模型。仿真表明该方法能较好的模拟车辆的实际行为。     

一个基于情感的自主非玩家角色模型

提出了一个新颖的基于情感的非玩家角色模型，此类非玩家角色有人造躯体，生活在虚拟的游戏场景中，并且具有自主行为。模型将情感系统、注意聚焦、意图以及表现系统集成在一起。模拟了人类的遗忘和情绪波动特性，以期使得游戏中的非玩家角色更接近于玩家角色或者真实玩家。为了表达情感和认知固有的不确定性，模型中用到了模糊表达。系统采用Model-View-Controller(MVC)的设计模式来实现，该模式把人工智能从游戏引擎中独立出来，采用接口和组件的思想来实现人工智能。

基于进化神经网络的玩家情感定量建模方法

玩家建模是游戏设计领域中一项重要的研究内容,国外学者已经提出了基于统计学的建模方式,但是这类方法需要主观构建数学模型,缺乏客观性。提出一种基于进化神经网络的定量建模方法,构建从游戏数据到玩家情感偏好之间的非线性模型。实验结果表明,该方法所建模型具有客观、高效的特点,并且具有较高准确度。     

基于社交网络的MMORPG玩家流失分析与预测

针对大型多人在线角色扮演游戏MMORPG(Massive Multiplayer Online Role-Playing Game)的玩家流失分析与预测问题,采用Cox比例风险模型建立玩家的流失模型,对玩家流失的因素进行分析,并对流失进行预测。分析玩家在游戏中的社交网络的特征(玩家的好友关系、二度好友关系、好友间聊天情况)对玩家流失行为的影响。对盛大"星辰变"游戏数据的实验表明,游戏中玩家所处的社交网络对玩家的流失行为具有显著影响,并能够提高预测效果。与支持向量机、Logistic回归和朴素贝叶斯分类进行对比,表明Cox模型更加适用于该玩家流失预测问题。     

机核游戏宅男的有氧运动

某游戏达人早年间于论坛写的一篇文章颇为疯转,名日《论PC玩家的悲哀》．文章大谈PC游戏方方面面的乏善可陈,得到了大批主机玩家的一致认可．虽然文章颇显主观,但却道出了中国游戏市场一个毋庸置疑的现实70％以上的游戏发烧友都是主机玩家,那么机核．就是这70％人中的一小撮”极端分子“所创立的主机游戏玩家交流的大本营。     

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.     

一种自适应子融合集成多分类器方法

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.     

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.     

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008     

Explanation and prediction: an architecture for default and abductive reasoning

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.     

Three Process Perspectives: Organizations, Teams, and People

This paper provides the author's personal views and perspectives on software process improvement. Starting with his first work on technology assessment in IBM over 20 years ago, Watts Humphrey describes the process improvement work he has been directly involved in. This includes the development of the early process assessment methods, the original design of the CMM, and the introduction of the Personal Software Process (PSP)^SM and Team Software Process (TSP){^SM}. In addition to describing the original motivation for this work, the author also reviews many of the problems he and his associates encountered and why they solved them the way they did. He also comments on the outstanding issues and likely directions for future work. Finally, this work has built on the experiences and contributions of many people. Mr. Humphrey only describes work that he was personally involved in and he names many of the key contributors. However, so many people have been involved in this work that a full list of the important participants would be impractical.

基于复小波噪声方差显著修正的SAR图像去噪

提出了一种基于复小波域统计建模与噪声方差估计显著性修正相结合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像斑点噪声滤波方法。该方法首先通过对数变换将乘性噪声模型转化为加性噪声模型,然后对变换后的图像进行双树复小波变换(Dualtree Complex Wavelet Transform,DCWT),并对复数小波系数的统计分布进行建模。在此先验分布的基础上,通过运用贝叶斯估计方法从含噪系数中恢复原始系数,达到滤除噪声的目的。实验结果表明该方法在去除噪声的同时保留了图像的细节信息,取得了很好的降噪效果。
