Towards bridging the gap between deep learning and biology (Yoshua Bengio, 2016)

Title: Towards bridging the gap between deep learning and biology Who: Yoshua Bengio When: 14:30 EST Where: AA 3195 We explore the following crucial question: how could brains potentially perform the kind of powerful credit assignment that allows hidden layers of a very deep network to be trained and that has been so successful with backprop in deep nets recently? Global reinforcement learning signals have too much variance (scaling with the number of neurons or synapses) to be credible from a machine lear
