提出了一种无师训练的fuzzymin max人工神经网络,它兼有一般fuzzymin max网与ART2网的优点,既弥补了fuzzymin max网不能自适应在线学习新类的缺陷,又消除了ART2网警戒门限过高的弊病.经模式识别仿真对比,对同样的输入数据,文中提出的网络用较低的警戒门限值即可达到ART2用很高的警戒门限值才能达到的分类效果,且计算量大大减少.得到的结论是:对模式识别而言,文中提出的网络比fuzzymin max网和ART2网更具有实用价值. 相似文献

自2017年8月DARPA公布“马赛克战”作战概念以来,世界各国都高度关注这一新型作战概念,学者们对“马赛克战”的研究也逐渐走向深入。本文首先从国际形势、美军装备特点、人工智能技术等方面分析了“马赛克战”的提出背景,回顾了其发展历程,剖析了其概念内涵,并从三个角度分析了其主要特点。接着着眼未来,从革新理念、鼓励创新、形成质变等视角探讨了“马赛克战”对装备体系试验鉴定领域未来发展方向的启示,重点论述了装备体系试验鉴定要向全智能作战体系试验鉴定方向发展的观点。最后聚焦当下,阐述了现阶段试验鉴定工作应重点关注动态互联互通性测试、互操作能力验证、新型仿真试验技术、系统自主能力等级评估及决策可解释性评估等五个方面的内容。 相似文献

Many observers anticipate “arms races” between states seeking to deploy artificial intelligence (AI) in diverse military applications, some of which raise concerns on ethical and legal grounds, or from the perspective of strategic stability or accident risk. How viable are arms control regimes for military AI? This article draws a parallel with the experience in controlling nuclear weapons, to examine the opportunities and pitfalls of efforts to prevent, channel, or contain the militarization of AI. It applies three analytical lenses to argue that (1) norm institutionalization can counter or slow proliferation; (2) organized “epistemic communities” of experts can effectively catalyze arms control; (3) many military AI applications will remain susceptible to “normal accidents,” such that assurances of “meaningful human control” are largely inadequate. I conclude that while there are key differences, understanding these lessons remains essential to those seeking to pursue or study the next chapter in global arms control. 相似文献

The rhino is going extinct due to poaching at a rate which far outstrips current law enforcement or conservation efforts to halt their decline. A critical aspect of counter-poaching failures to date is an inaccurate view of the nature of poaching as a crime. Rather than demand-side efforts, attacking elusive smuggling networks or expensive technical solutions like drones, this article notes how a quasi-military tactical approach of ‘combat tracking’ offers the best way to protect the species. Based on wide ranging interviews and fieldwork across dozens of parks in southern Africa, it demonstrates how the current restricted range of the rhino, and the rarity of skilled poachers, makes a tactical solution the most effective to date. 相似文献

Military operations increasingly require cooperation between agencies within the same nation, but also collaboration with security and military organizations internationally. Throughout history multinational military cooperation has often been an appropriate way to conduct major operations; national manpower and material resources are generally insufficient to address the demands of missions worldwide. The desire to optimize the use of scarce research and development and investment capabilities, the need for international legitimacy and political support, and the fact that today’s risks transcend national borders, have rendered multinational cooperation in the security domain unavoidable. With joint operations comes the requirement for multi-partner- and multinational information sharing. However, information sharing has both advantages and costs, and is subject to both enabling factors as well as barriers. This paper reflects on theories, both classical and current, as well as empirical case studies, to examine the pros and cons of multinational information sharing, and the factors that conduce or interfere with the transmission and the receipt of intelligence. The importance of a holistic approach and of learning lessons learned are two key lessons gleaned from the analysis, along with an emphasis on developing both the organizational and the interpersonal enablers of information sharing. 相似文献

人工势场法是一种常用的具有算法简单和便于实时控制的局部路径规划方法,但存在容易产生局部极小值的问题。基于模糊逻辑的局部路径规划法具有环境适应性强等优点,它在连续论域内采用模糊路径规划时,计算量比较大。提出了一种将人工势场法和模糊逻辑法相结合进行局部路径规划的混合算法。具体方法是在一般情况下采用人工势场法进行局部路径规划,当产生局部极小值时,采用模糊逻辑法进行局部路径规划。仿真结果表明,该方法能有效地解决局部极小值问题,给智能车规划出光滑的路径。 相似文献
