基于数据的深度学习方法在自然语言处理领域方兴未艾,但种种问题也开始显现.语言的经典的组合原则被打破,让机器“理解”语言变得不再重要,符号之间的黏性完全由样本统计决定,违背了人类语言理解和习得的主观经验.本文针对这一系列问题,详尽阐述了经典数字计算机的运算和决策过程,并对其处理部分模糊性问题时采取的策略进行简要介绍,指出即使是在统计学习过程中,人类偏好也无时无刻不在扮演着关键作用,规律性不可能无条件地从海量数据中自动浮现.逻辑学家和数据科学家有责任揭示这些主观偏好,这不仅是算法可解释性的外在需要,也是提高运算效率的正途.

针对符号网络条件下扩散耦合多智能体网络的可控性进行了研究.基于广义几乎等价划分的方法,结合系统系数矩阵的限制条件,运用图理论,给出了此时系统可控子空间维数的上界,并给出了系统可控的一个必要条件,即系统可控时,划分中所有胞腔都是平凡的.给出了一种用来计算最大领导者孤立广义几乎等价划分的算法.此外,还证明了结构平衡条件下,如果从同一个顶点集中选择领导者,则扩散耦合多智能体系统的可控性与对应的全正网络的可控性是等价的,而与系统系数矩阵的选取无关.
