情感作为人类的高级认知,在环境学习和环境理解方面具有重要意义.将情感引入机器人搜索任务,同时结合记忆机理,提出一种具有情感和记忆机制的认知模型,由内部状态、感受器、环境状态系统、情感系统、动态知识库、行为决策系统以及执行器7部分组成.情感系统包含情感生成、情感状态以及情感记忆3个模块,其中,情感记忆用于提供内部奖励.记忆功能在动态知识库中实现.基于强化学习理论框架,将情感内部奖励与记忆进行融合,形成新的奖励机制,并设计相关认知学习算法.以需要“能量补给”的迷宫机器人搜索任务对所提出认知模型进行验证,结果发现,当面对不同情境时,机器人会产生不同的情感.结合前期记忆,机器人所作决策更“拟人”,表明情感和记忆机制设计的有效性.将所提出认知模型、无情感决策认知模型、基于ε-greedy策略的Q学习算法进行对比,结果表明,情感和记忆的引入,能够提高机器人的学习效率,同时学习过程更稳定. 相似文献

人工情感在机器人的研究中至关重要,简要概括了当前人工情感的应用.在借鉴情感学习控制的理论的基础上,融入了进化控制的思想,设计出了一种基于人工情感的控制体系结构,在此结构中包含有基于遗传算法的进化控制系统、神经和人工情感控制系统.机器人通过神经系统接受环境信息并进行行为决策,行为决策的效果通过情感学习模型进行反馈.情感学习模型根据机器人的内、外环境状态,产生情感因子(即生物激素),再由情感因子来调节神经系统的记忆和行为决策,最后神经系统的记忆与行为模块又由进化系统得以继承.该控制结构加强了机器人在动态环境中的学习和自适应能力.仿真实验验证了该控制结构的有效性,仿真结果也表明机器人具有很强的学习和自适应能力. 相似文献

根据基本情感理论建立了家庭服务机器人的情感状态概率空间模型,并应用马尔可夫链的特性,建立了基于隐马尔可夫模型的情感计算模型.详细地阐述了该情感计算模型中各参数的意义以及估算方法.通过仿真实验验证了该情感计算模型可以较好地模拟情感状态的自发转移,以及在外部刺激作用下的情感转移.通过对实验数据分析,发现机器人的情感经外部刺激作用或者自发演变,最终趋于稳定状态,这个稳定状态与情感转移概率矩阵有关,而与机器人所处的初始情感状态无关. 相似文献

机器人情感建模是研究情感机器人的热点问题。文中以情感心理学知识为基础,模拟具有不同个性的情感机器人在外界刺激作用下情感动态变化的过程,研究个性和外界刺激对情感转移过程的影响。采用基于状态空间的情感空间模型来描述机器人的情感状态,并用HMM过程来模拟情感状态的转移过程。但HMM过程只能求得当前情感状态的概率,为得到具体的情感状态,文中提出一种基于状态空间与概率空间映射的极大相似度匹配的情感转移模型。首先利用HMM过程计算出当前情感概率,然后通过极大相似度匹配来得到转移后具体的情感状态。通过调节模型参数来模拟不同个性和外界刺激,该模型能有效模拟情感状态变化过程。实验结果验证模型模拟的情感变化过程符合人类情感变化的一般规律。 相似文献

Affective computing is important in human–computer interaction. Especially in interactive cloud computing within big data, affective modeling and analysis have extremely high complexity and uncertainty for emotional status as well as decreased computational accuracy. In this paper, an approach for affective experience evaluation in an interactive environment is presented to help enhance the significance of those findings. Based on a person-independent approach and the cooperative interaction as core factors, facial expression features and states as affective indicators are applied to do synergetic dependence evaluation and to construct a participant’s affective experience distribution map in interactive Big Data space. The resultant model from this methodology is potentially capable of analyzing the consistency between a participant’s inner emotional status and external facial expressions regardless of hidden emotions within interactive computing. Experiments are conducted to evaluate the rationality of the affective experience modeling approach outlined in this paper. The satisfactory results on real-time camera demonstrate an availability and validity comparable to the best results achieved through the facial expressions only from reality big data. It is suggested that the person-independent model with cooperative interaction and synergetic dependence evaluation has the characteristics to construct a participant’s affective experience distribution, and can accurately perform real-time analysis of affective experience consistency according to interactive big data. The affective experience distribution is considered as the most individual intelligent method for both an analysis model and affective computing, based on which we can further comprehend affective facial expression recognition and synthesis in interactive cloud computing. 相似文献

The difficulty in opening and closing the tailgate of sport utility vehicles (SUV) is important as one of the items of JD power’s Initial Quality Study (IQS). This study aimed to evaluate the perceived exertion and satisfaction in opening and closing SUV tailgates and explain them with the mechanical force. The study measured the mechanical open and close force for 33 SUV tailgates and evaluated perceived exertion and satisfaction of opening and closing with 84 male participants from 20’s to 50’s. The regression models of perceived exertion and satisfaction showed that initial closing and opening force, the difference between initial and maximum closing force, and the difference between an initial close angle and auto-fall angle should be small for a positive effect. In addition, the IQS score of tailgates is more related to perceived exertion and satisfaction in closing than those in the opening. The results of the study will be helpful to design and test the mechanical open and close structure of SUV tailgates. 相似文献

The disenchantment of affect 总被引:1,自引:1,他引:0
Phoebe Sengers Kirsten Boehner Michael Mateas Geri Gay 《Personal and Ubiquitous Computing》2008,12(5):347-358
In computing design, experience is often broken down, compartmentalized, and engineered: a process that often disenchants
the original experience. In this paper, we demonstrate the possibility to design for experience, not by formalizing and rationalizing
it, but instead by supporting open-ended engagement and appropriation. We illustrate this approach through Affector, a case
study in affective computing, in which we focus on user interpretation and construction of emotional experience over its computational
modeling. We derive design and evaluation strategies for enchantment that focus on supporting the ongoing construction and
interpretation of experience by human participants over the course of interaction. We suggest that enchanting experiences
may be designed only by approaching enchantment obliquely: not by engineering it in, but by providing opportunities where
it may emerge. 相似文献
