Whole brain Probabilistic Generative Model toward Realizing Cognitive Architecture for Developmental Robots

Through the developmental process, they acquire basic physical skills (such as reaching and grasping), perceptional skills (such as object recognition and phoneme recognition), and social skills (such as linguistic communication and intention estimation) (Taniguchi et al., 2018). This open-ended online learning process involving many types of modalities, tasks, and interactions is often referred to as lifelong learning (Oudeyer et al., 2007; Parisi et al., 2019). The central question in next-generation artificial intelligence (AI) and developmental robotics is how to build an integrative cognitive system that is capable of lifelong learning and humanlike behavior in environments such as homes, offices, and outdoor. In this paper, inspired by the human whole brain architecture (WBA) approach, we introduce the idea of building an integrative cognitive system using a whole brain probabilistic generative model (WB-PGM) (see 2.1). The integrative cognitive system can alternatively be referred to as artificial general intelligence (AGI) (Yamakawa, 2021). Against this backdrop, we explore the process of establishing a cognitive architecture for developmental robots. Cognitive architecture is a hypothesis about the mechanisms of human intelligence underlying our behaviors (Rosenbloom, 2011). The study of cognitive architecture involves developing a presumably standard model of the humanlike mind (Laird et al., 2017).
