Here present the past awardees of the WBAI Incentive Award, which is given to persons who achieved (potentially) prolific results in promoting the development of brain-inspired artificial general intelligence (AGI).
She was the first to lead a research effort to build a brain reference architecture (BRA) by assigning computational functions consistent with the anatomy of the brain. She published the results of its application to the pathway integration function of the medial entorhinal cortex in an international journal. She was also involved in the formulation of the BRA construction method as the SCID method. These efforts have facilitated designing specifications of brain-inspired artificial intelligence for regions of the brain.
They have implemented a virtual experimental environment, evaluation system, and other equipment as a platform to promote research and development of common sense reasoning held by animal intelligences (e.g., object persistence, numerical capabilities, and first-level causal inference), and used it to run a competition involving more than 60 teams from around the world. Such animal intelligence is the foundation of human-like intelligence, and this award is given in recognition of the promotion of technological development of artificial general intelligence through such activities.
He has made significant academic contributions to the research and development of the deep generative models to serve for brain-inspired AI, notably in the proposal and development of Joint Multimodal Variational Autoencoder (JMVAE), which can convert information bi-directionally across modality differences, and the joint development of Neuro-Serket*, a cognitive system. Furthermore, he has propagated the effect of the models by promoting the implementation of the models with a tool called Pixyz that he produced. The award is given in recognition of these achievements that have promoted the technological development of the whole brain architecture.

He conducted experiments in a 3D virtual environment to show that homeostatic properties such as food intake, poison avoidance, and energy gain emerge from the reinforcement learning algorithm, which is considered to be the problem of maximizing the probability of survival, and published the result on the Journal of Artificial General Intelligence. The emergence of behaviors for homeostasis will contribute the brain-inspired AGI development in terms of realizing autonomous survival, creating the basis for modeling emotions, and discussing the convergence of instrumental subgoals.
He launched a new research approach called “connectome informatics” to extract knowledge of the essential structure from neural circuits (connectome) for brain-inspired artificial intelligence, and made academic presentations in Japan and overseas. Connectome informatics continues as a research activity within WBAI also with a large exterior effect. He also created and operated the Nico Nico AI School, a hands-on meeting and online course, contributing to the fostering of brain-inspired artificial intelligence developers.
He proposed extended model of restricted Boltzmann machine (RBM), inspired by the hippocampus and based on the accumulator-based arbitration model (ABAM), a multi-module arbitration method inspired by the prefrontal cortex, and it was appraised in both inside and outside Japan. Both methods were made public and contributed to the public interest.
He proposed a model (SpCoSLAM) that integrates self-localization and map generation functions corresponding to the hippocampus, and word segmentation from speech information corresponding to the neocortex and clustering based on multimodal information such as positions, images and words. It was proposed and implemented, presented at academic conferences in Japan and overseas, and the source code has been released publicly.
He developed the AI learning environment called Life in Silico (LIS), which combines Unity the game engine and DQN-based agents in a form easy for general users to use. He organized a LIS hackathon with about 100 engineers and posted the result on numerous web media. LIS has a tutorial in a book, has been recognized as a tool for beginners, and has spread to the game industry as he gave a talk at the game conference CEDEC 2016. This has made a significant contribution to the promotion of technology development for the whole brain architecture.
