经济选择行为中的监督目标导向算法:一种Actor-Critic方法

A Supervised Goal Directed Algorithm in Economical Choice Behaviour: An Actor-Critic Approach

Keyvan Yahya

摘要:

本文的目的是找到一种算法结构,提供预测和解释经济选择行为,特别是在不确定性(随机政策)下,通过操纵流行的演员-评论家学习方法,以符合要求,我们一直委托,因为我们的神经经济学领域的曙光。在略读一些与我们的讨论相关的神经经济学基础知识的同时,我们将试图概述一些迄今为止为模拟选择过程而做的重要工作。关于神经学研究结果表明存在通过基底神经节一直执行到皮层下区域的两个特定功能,即“奖励”和“信念”,我们将提供演员/评论家算法的修改版本,以阐明这些功能之间的关系,最重要的是解决所谓的演员-评论家算法的挑战,即,缺乏继承或层次结构,避免了系统在连续时间任务中进化,从而可能不会出现收敛。

英文摘要:

This paper aims to find an algorithmic structure that affords to predict and explain economical choice behaviour particularly under uncertainty(random policies) by manipulating the prevalent Actor-Critic learning method to comply with the requirements we have been entrusted ever since the field of neuroeconomics dawned on us. Whilst skimming some basics of neuroeconomics that seem relevant to our discussion, we will try to outline some of the important works which have so far been done to simulate choice making processes. Concerning neurological findings that suggest the existence of two specific functions that are executed through Basal Ganglia all the way up to sub- cortical areas, namely 'rewards' and 'beliefs', we will offer a modified version of actor/critic algorithm to shed a light on the relation between these functions and most importantly resolve what is referred to as a challenge for actor-critic algorithms, that is, the lack of inheritance or hierarchy which avoids the system being evolved in continuous time tasks whence the convergence might not be emerged.
