【摘要】：現(xiàn)實生活中人們對事物的觀念(態(tài)度)除了自身的主觀因素外,還會受到他人的影響而發(fā)生改變。"少數(shù)服從多數(shù)"是一種常見的從眾心理,是導(dǎo)致人們產(chǎn)生從眾行為而改變自身觀念的重要誘因。為揭示該心理作用下人們的觀念演化規(guī)律,本文建立了一個基于從眾學(xué)習(xí)機制的觀念演化模型。用一個稱為觀點值的變量表示個體的觀念,在小世界網(wǎng)絡(luò)上模擬并考察個體觀念值的更新演化過程。研究表明:固守自身觀念的個體對網(wǎng)絡(luò)群體最終的觀念共識具有牽引作用,觀念共識值都趨向這些個體的固守觀念值;從眾系數(shù)越大,群體越容易達成觀念共識。群體中固守觀念的個體所占比例越大,達成觀念共識的速度越快;但群體在局部學(xué)習(xí)機制下受到網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)影響,演化過程相對復(fù)雜,在全局學(xué)習(xí)機制下更易達成觀念共識。
[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.
