Reinforcement learning when your life depends on it: a neuro-economic theory of learning (2024)
Preprint / Working Paper
Jiang, J., Foyard, E., & van Rossum, M. C. Reinforcement learning when your life depends on it: a neuro-economic theory of learning

Synaptic plasticity enables animals to adapt to their environment, but memory formation can consume a substantial amount of metabolic energy, potentially impairing survival. Hence, a neuro-economic dilemma arises whether learning is a profitable inve... Read More about Reinforcement learning when your life depends on it: a neuro-economic theory of learning.

Competitive plasticity to reduce the energetic costs of learning (2023)
Preprint / Working Paper
van Rossum, M. C. Competitive plasticity to reduce the energetic costs of learning

The brain is not only constrained by energy needed to fuel computation, but it is also constrained by energy needed to form memories. Experiments have shown that learning simple conditioning tasks already carries a significant metabolic cost. Yet, le...

Lazy learning: a biologically-inspired plasticity rule for fast and energy efficient synaptic plasticity (2023)
Preprint / Working Paper
Pache, A., & Van Rossum, M. Lazy learning: a biologically-inspired plasticity rule for fast and energy efficient synaptic plasticity

When training neural networks for classification tasks with backpropagation, parameters are updated on every trial, even if the sample is classified correctly. In contrast, humans concentrate their learning effort on errors. Inspired by human learnin...

Estimating the energy requirements for long term memory formation (2023)
Preprint / Working Paper
Girard, M., Jiang, J., & van Rossum, M. C. Estimating the energy requirements for long term memory formation

Brains consume metabolic energy to process information, but also to store memories. The energy required for memory formation can be substantial, for instance in fruit flies memory formation leads to a shorter lifespan upon subsequent starvation (Mery...

Functional consequences of pre- and postsynaptic expression of synaptic plasticity (2016)
Preprint / Working Paper
Costa, R. P., Mizusaki, B. E., Jesper Sjöström, P., & van Rossum, M. C. W. Functional consequences of pre- and postsynaptic expression of synaptic plasticity

Growing experimental evidence shows that both homeostatic and Hebbian synaptic plasticity can be expressed presynaptically as well as postsynaptically. In this review, we start by discussing this evidence and methods used to determine expression loci...
