Putting An End to End-to-End: Gradient-Isolated Learning of Representations

1 code implementation NeurIPS 2019 Sindy Löwe, Peter O'Connor, Bastiaan S. Veeling

We propose a novel deep learning method for local self-supervised representation learning that does not require labels nor end-to-end backpropagation but exploits the natural order in data instead.

Initialized Equilibrium Propagation for Backprop-Free Training

no code implementations ICLR 2019 Peter O'Connor, Efstratios Gavves, Max Welling

In response to this, Scellier & Bengio (2017) proposed Equilibrium Propagation - a method for gradient-based train- ing of neural networks which uses only local learning rules and, crucially, does not rely on neurons having a mechanism for back-propagating an error gradient.

Learning a Representation Map for Robot Navigation using Deep Variational Autoencoder

1 code implementation5 Jul 2018 Kaixin Hu, Peter O'Connor

For the navigation problem, we map the starting image and destination image to the latent space, then optimize a path on the learned manifold connecting the two points, and finally map the path back through decoder to a sequence of images.

Temporally Efficient Deep Learning with Spikes

1 code implementation ICLR 2018 Peter O'Connor, Efstratios Gavves, Max Welling

We present a variant on backpropagation for neural networks in which computation scales with the rate of change of the data - not the rate at which we process the data.

Sigma Delta Quantized Networks

1 code implementation7 Nov 2016 Peter O'Connor, Max Welling

Thus the amount of computation that the network does scales with the amount of change in the input and layer activations, rather than the size of the network.

Deep Spiking Networks

1 code implementation26 Feb 2016 Peter O'Connor, Max Welling

Our network is "spiking" in the sense that our neurons accumulate their activation into a potential over time, and only send out a signal (a "spike") when this potential crosses a threshold and the neuron is reset.
