摘要:

构建一个类人的综合性人工认知系统,即人工通用智能(AGI),是人工智能(AI)领域的圣杯。此外,使人工系统能够实现认知发展的计算模型将是脑和认知科学的极好参考。本文介绍了一种方法来开发一个认知架构,通过整合基本的认知模块,使培训的模块作为一个整体。这种方法基于两个想法:(1)大脑启发的AI,学习人类大脑结构以构建人类水平的智能,以及(2)基于概率生成模型(PGM)的认知系统,通过集成PGM为开发机器人开发认知系统。开发框架被称为全脑PGM(WB-PGM),它与现有的认知架构有根本的不同,因为它可以通过基于感觉运动信息的系统不断学习。在这项研究中,我们描述了WB-PGM的基本原理,基于PGM的基本认知模块的现状,它们与人脑的关系,认知模块的整合方法,以及未来的挑战。我们的研究结果可以作为脑研究的参考。由于PGM描述变量之间的明确信息关系,这种描述提供了从计算科学到脑科学的可解释指导。通过提供这些信息,神经科学的研究人员可以向人工智能和机器人技术的研究人员提供反馈,说明当前模型在大脑方面缺乏什么。此外,它可以促进神经认知科学以及人工智能和机器人技术研究人员之间的合作。

英文摘要:

Building a humanlike integrative artificial cognitive system, that is, an artificial general intelligence (AGI), is the holy grail of the artificial intelligence (AI) field. Furthermore, a computational model that enables an artificial system to achieve cognitive development will be an excellent reference for brain and cognitive science. This paper describes an approach to develop a cognitive architecture by integrating elemental cognitive modules to enable the training of the modules as a whole. This approach is based on two ideas: (1) brain-inspired AI, learning human brain architecture to build human-level intelligence, and (2) a probabilistic generative model(PGM)-based cognitive system to develop a cognitive system for developmental robots by integrating PGMs. The development framework is called a whole brain PGM (WB-PGM), which differs fundamentally from existing cognitive architectures in that it can learn continuously through a system based on sensory-motor information. In this study, we describe the rationale of WB-PGM, the current status of PGM-based elemental cognitive modules, their relationship with the human brain, the approach to the integration of the cognitive modules, and future challenges. Our findings can serve as a reference for brain studies. As PGMs describe explicit informational relationships between variables, this description provides interpretable guidance from computational sciences to brain science. By providing such information, researchers in neuroscience can provide feedback to researchers in AI and robotics on what the current models lack with reference to the brain. Further, it can facilitate collaboration among researchers in neuro-cognitive sciences as well as AI and robotics.
