论文摘要
做出决定可以自由前提是环境和决策引擎中存在一些不确定性。前者反映在由于交流引起的行为变化上:很少的变化表明僵化的环境;生产力的变化表现出适度的不确定性,但是巨大的沟通努力,几乎没有生产力的变化来表征混乱的环境。因此,沟通,有效的决策和生产行为改变是相关的。熵衡量环境的不确定性,并且在熵范围内进行交流支持有效的决策。此猜想在这里被称为决策的潜在生产力。 决策因果的计算引擎也应具有一定的不确定性。但是,标准图灵机执行的计算是预先确定的。为了克服这种限制,提出了一种称为关系划分的熵计算模式。其以表格格式实现已用于建模关联内存。当前的理论和实验表明熵权衡:在某些熵范围内计算有效,但是如果熵太低的计算太刚性,并且计算太高,则计算太高了。计算机的熵权衡取舍对应于环境决策的潜在生产力。 该理论被称为面向互动的认知结构。记忆,感知,行动和思想涉及一定程度的不确定性和决策,在这样的程度上可能是免费的。总体理论支持理性的生态观点。在神经科学研究中已经测量了大脑的熵,而本理论支持大脑是熵机。本文以许多可能在经验上测试的预测结论。
Making decisions freely presupposes that there is some indeterminacy in the environment and in the decision making engine. The former is reflected on the behavioral changes due to communicating: few changes indicate rigid environments; productive changes manifest a moderate indeterminacy, but a large communicating effort with few productive changes characterize a chaotic environment. Hence, communicating, effective decision making and productive behavioral changes are related. The entropy measures the indeterminacy of the environment, and there is an entropy range in which communicating supports effective decision making. This conjecture is referred to here as the The Potential Productivity of Decisions. The computing engine that is causal to decision making should also have some indeterminacy. However, computations performed by standard Turing Machines are predetermined. To overcome this limitation an entropic mode of computing that is called here Relational-Indeterminate is presented. Its implementation in a table format has been used to model an associative memory. The present theory and experiment suggest the Entropy Trade-off: There is an entropy range in which computing is effective but if the entropy is too low computations are too rigid and if it is too high computations are unfeasible. The entropy trade-off of computing engines corresponds to the potential productivity of decisions of the environment. The theory is referred to an Interaction-Oriented Cognitive Architecture. Memory, perception, action and thought involve a level of indeterminacy and decision making may be free in such degree. The overall theory supports an ecological view of rationality. The entropy of the brain has been measured in neuroscience studies and the present theory supports that the brain is an entropic machine. The paper is concluded with a number of predictions that may be tested empirically.
