Learning to solve the credit assignment problem

BJ Lansdell, PR Prakash, KP Kording - arxiv preprint arxiv:1906.00889, 2019 - arxiv.org
Backpropagation is driving today's artificial neural networks (ANNs). However, despite
extensive research, it remains unclear if the brain implements this algorithm. Among …

Spiking allows neurons to estimate their causal effect

B James Lansdell, KP Kording - bioRxiv, 2018 - biorxiv.org
Neural plasticity can be seen as ultimately aiming at the maximization of reward. However,
the world is complicated and nonlinear and so are neurons' firing properties. A neuron …

Neural spiking for causal inference

BJ Lansdell, KP Kording - 2018 - europepmc.org
When a neuron is driven beyond its threshold it spikes, and the fact that it does not
communicate its continuous membrane potential is usually seen as a computational liability …
