Brains consist of components that are low-precision (2-3 bit), sparsely connected (p<0.01), and very slow (milliseconds), yet they outperform competing approaches on a range of fundamental applications such as visual and auditory recognition. Brain circuits are circuits, albeit with unusual engineering designs, and they are becoming understood computationally. This talk will characterize typical brain circuit architectures and their operating rules; show examples of how such circuits give rise to novel algorithms for learning; and illustrate instances of these methods used in robot applications.
