Abstract
Current AI originated from mimicking the way our brain processes information such as layered structures, convolutions, sigmoidal activation functions etc. However, it deviates significantly from brain dynamics as well: the information carriers in our brain are spikes (0 or 1) and our brain employs many advanced cognitive functions including attention, memory, emotion etc. to process information. In the talk, we will first review some of our current advances in exploring brain functions, in particular, in emotion processing. We then summarize our recent efforts on constructing digital brains both at resting states and interacting with environments.
