本文提出情绪作为生物系统内在有色噪声的模型，通过概率决策与模仿机制模拟异质社会，发现八种运行类型，并解决埃尔斯伯格悖论。
AI 中文摘要
本文提出并论证了生物系统中的情绪类似于内在有色噪声的观点。我们提出一个模型，描述生物网络在有色噪声影响下的运行动力学。生物网络的智能体既可以代表生物物种（如人类和动物），也可以代表大脑神经元，或神经网络的节点。在生物噪声网络中，操作行动或决策不仅基于对备选方案效用的评估，还基于智能体的情绪。该模型是概率性的，备选方案的选择由相关概率表征。在初始步骤中，智能体独立做出决策，然后开始相互交换信息并模仿其他智能体的行动，从而形成相互作用的智能体生物网络。我们对一个由三组智能体组成的异质社会进行了数值模拟：一组具有长程记忆，另一组具有短程记忆，第三组为超级理性智能体，严格基于效用行事，缺乏情绪。不同群体中的意见动态可以是平滑的、振荡的或混沌的。总共发现了八种运行类型，取决于群体决策的动态。在强模仿效应下，决策选择的演化中出现混沌运动。我们展示了埃尔斯伯格悖论如何被解决，以及信息交换如何影响该悖论的动态。
英文摘要
The idea that emotions in biological systems are analogous to intrinsic colored noise is advanced and justified. A model describing the dynamics of operation of biological networks under the influence of colored noise is suggested. The agents of a biological network can be represented either by biological species, such as humans and animals, or by neurons of the brain, or by the nodes of a neural network. Operational actions, or decisions, in a biological noisy network are based not only on the evaluation of utility of alternatives, but also on the agents emotions. The model is probabilistic, with the choice of alternatives characterized by the related probabilities. At the initial step, the agents make decisions individually and then start exchanging information with each other and imitating the actions of other agents, thus forming a biological network of interacting agents. Numerical simulations are accomplished for a heterogeneous society consisting of three groups of agents, one group possessing long-range memory, the other group, short-range memory, and the third group of super-rational agents acting strictly on the basis of utility, being deprived of emotions. Dynamics of opinions in different groups can be smooth, oscillatory, or chaotic. Altogether, eight types of operation are found, depending on the dynamics of group decisions. Under strong imitation effect, there appears chaotic motion in the evolution of decision choice. It is shown how the Ellsberg paradox can be resolved and how the exchange of information influences the dynamics of this paradox.
