…for relating neurotransmitter levels to prediction errors and Bayesian uncertainties. He made contributions to unsupervised learning, including the wake-sleep algorithm for neural networks and the Helmholtz machine. Dayan studied mathematics at the University of Cambridge and then continued for a PhD in artificial…
Layers of the neural network. R, G are weights used by the wake-sleep algorithm to modify data inside the layers.
