The extensible Data-Brain model: Architecture, applications and directions

One of the key ideas in realizing human-like intelligence is to understand information-processing mechanisms in the human brain. Brain Informatics is a rapidly expanding interdisciplinary field to systematically utilize brain-related data, information and knowledge coming from the entire research process for indepth brain investigation. In the past few years, a data-centric conceptual brain model, namely Data-Brain, has been proposed, providing the foundation for the systematic Brain Informatics methodology. The Data Brain model constitutes a conceptual framework and detailed guideline for managing and analyzing brain big data. The development of Data-Brain model also demands the support from advanced technologies. This paper presents an extensible version of the Data-Brain with advanced computing techniques in the connected world. It provides a global understanding of how multidisciplinary techniques work together to tackle brain computing challenges. Particularly, the integrated K-I-D (Knowledge-Information-Data) loop is proposed, constructing a cycle as the thinking space to help pursue the systematic brain investigation, by which the extensible Data-Brain model continuously iterates and evolves through the never-ending learning. Such synergistic evolvement will power future progress for building intelligence systems and applications connected with the study of complex human brain. (c) 2020 Elsevier B.V. All rights reserved.
