Continual Reinforcement Learning with Multi-Timescale Replay
Christos Kaplanis, Claudia Clopath, Murray Shanahan
In this paper, we propose a multi-timescale replay (MTR) buffer for improving continual learning in RL agents faced with environments that are changing continuously over time at ti…
Cortical credit assignment by Hebbian, neuromodulatory and inhibitory plasticity
Johnatan Aljadeff, James D'amour, Rachel E. Field +2
The cortex learns to make associations between stimuli and spiking activity which supports behaviour. It does this by adjusting synaptic weights. The complexity of these transforma…
Learning spatiotemporal signals using a recurrent spiking network that discretizes time
Amadeus Maes, Mauricio Barahona, Claudia Clopath
Learning to produce spatiotemporal sequences is a common task that the brain has to solve. The same neural substrate may be used by the brain to produce different sequential behavi…
Policy Consolidation for Continual Reinforcement Learning
Christos Kaplanis, Murray Shanahan, Claudia Clopath
We propose a method for tackling catastrophic forgetting in deep reinforcement learning that is \textit{agnostic} to the timescale of changes in the distribution of experiences, do…
Gap junction plasticity can lead to spindle oscillations
Guillaume Pernelle, Wilten Nicola, Claudia Clopath
Patterns of waxing and waning oscillations, called spindles, are observed in multiple brain regions during sleep. Spindle are thought to be involved in memory consolidation. The or…
Acetylcholine-modulated plasticity in reward-driven navigation: a computational study
Sara Zannone, Zuzanna Brzosko, Ole Paulsen +1
Neuromodulation plays a fundamental role in the acquisition of new behaviours. Our experimental findings show that, whereas acetylcholine biases hippocampal synaptic plasticity tow…
