基于从众学习机制的观念演化模型
发布时间：2018-08-20 19:36
【摘要】：现实生活中人们对事物的观念(态度)除了自身的主观因素外,还会受到他人的影响而发生改变。"少数服从多数"是一种常见的从众心理,是导致人们产生从众行为而改变自身观念的重要诱因。为揭示该心理作用下人们的观念演化规律,本文建立了一个基于从众学习机制的观念演化模型。用一个称为观点值的变量表示个体的观念,在小世界网络上模拟并考察个体观念值的更新演化过程。研究表明:固守自身观念的个体对网络群体最终的观念共识具有牵引作用,观念共识值都趋向这些个体的固守观念值;从众系数越大,群体越容易达成观念共识。群体中固守观念的个体所占比例越大,达成观念共识的速度越快;但群体在局部学习机制下受到网络拓扑结构影响,演化过程相对复杂,在全局学习机制下更易达成观念共识。
[Abstract]:In real life, people's attitudes to things change in addition to their own subjective factors. " Minority clothing from majority "is a kind of common herd psychology, and it is an important inducement to cause people to behave in conformity and change their own ideas." In order to reveal the law of people's concept evolution under the influence of psychology, a conceptual evolution model based on herd learning mechanism is established in this paper. The concept of individual is represented by a variable called viewpoint value, and the process of updating the value of individual concept is simulated and investigated on the small-world network. The results show that the individuals who adhere to their own ideas have the traction role to the ultimate concept consensus of the network group, and the values of the concept consensus tend to the values of these individuals, and the larger the conformity coefficient is, the easier the group can reach the consensus of ideas. The larger the proportion of the individuals who stick to the idea, the faster the consensus of ideas is reached, but the group is affected by the network topology under the local learning mechanism, and the evolution process is relatively complex, so it is easier to reach a consensus of ideas under the global learning mechanism.
