Brains (1) Human brain Von Neumann machine
Face recognition: <500ms Neurons are slow:
Critical path is a handful of “gates” Fundamentally different computational model
Made of shoddy, unreliable parts“…neurons are noisy, unreliable devices, … the nervous system
averages over many cells to compensate for these shoddy components.”
-Christof Koch
We can build it. We have the technology.

Brains (2) Human neocortex:
~20B neurons, ~200T synapses Physiologically homogenous Hypothesis: runs common algorithm
Apply architecture 101? Abstraction layers Hierarchy and replication
Scientific understanding incomplete Several plausible hypotheses Difficult to study brains in situ
Building leads to understanding [Anant’s keynote] Synthetic artifacts much easier to study
Let’s Build Brains!
