- Koshkin 5y agoLooks like what the Quanta article refers to is not so much "computations made in cells" as "how computationally complex a faithful model of a neuron would be."
- AlexCoventry 5y agoBased on the Quanta article, they're only measuring complexity in terms of how complex a neural net needs to be to faithfully learn a neuron's output (presumably by SGD.) That's probably only a weak upper bound on the complexity, though. There may be more parsimonious ways to simulate the neuron which are expensive to represent in a neural net, or which are hard for SGD to learn.
