We show analytically that training a neural network by conditioned stochastic mutation or neuroevolution of its weights is equivalent, in the limit of small mutations, to gradient descent on the loss ...

Many microorganisms swim by performing larger non-reciprocal shape deformations that are initiated locally by molecular motors. However, it remains unclear how decentralized shape control determines ...

Modern artificial intelligence is built to mimic nature—the field’s main pursuit is replicating in a computer the same decision-making prowess that humankind creates biologically. For the better part ...
