查询词典 statistical decision function

Two normal forms, best-simple normal form and literal normal form, are presented at first in order to eliminate the complexity of formulas decision. Based on the two normal forms, a deduction proof of decidability theorem in L and a decision algorithm P based on deduction for proportional formulas are given and a decision machine found on P, DMBD, is also designed.

首先提出了消解复杂性的两种范式：最简范式和文字范式，在此基础上给出了L的可判性定理的演绎证明及命题公式的演绎判定算法P，并基于ML语言设计了基于P的演绎判定机DMBD。

To better integrate the decision progress with the technology of data warehouse, a mathematical description of the general problem's decision-making process was proposed and the knowledge classification of decision domain based on the mathematical description was provided as well.

为了将数据仓库技术和决策过程更好地结合，给出了一般问题决策过程的数学描述以及在此基础上的决策空间的知识分类。

Based on that a model of decision under uncertainty is established to explain decision problems when the decision maker is facing uncertainty, among which is the famous Ellsberg Paradox.

Taking the undergraduates as participants, the research, through six successive experiments, has inquired into the influence of the three attention levels of information (focused attention, divided attention and non-attention) upon the heuristic social decision making in the three types of tasks (choice, memory, estimate of quantity and frequency) in decision making. And, by taking account of the different effects, such as mere exposure, priming of experience, illusory correlation, self-relevance, the research has taken a further step and made a quite comprehensive study on the effect and existing biases in using heuristic decision making at different attention levels.

本研究以大学生为被试，通过6个系列实验，探讨了在三种不同的决策任务类型(选择、记忆、数量和频率估计)中，信息的三种注意水平(集中注意、分散注意和无注意)对人类使用启发法进行社会决策的影响；并进一步结合社会判断和决策中存在的纯粹接触、经验启动、错觉相关、自我关联等效应，较为全面地研究了人们在不同注意水平上使用启发法决策的效果及存在的偏差。
