Random Feedback Alignment Algorithms to train Neural Networks: Why do they Align?

Dominique Chu, Florian Bacho

Feedback alignment algorithms are an alternative to backpropagation to train neural networks, whereby some of the partial derivatives that are required to compute the gradient are…

Exploring Tradeoffs in Spiking Neural Networks

Florian Bacho, Dominique Chu

Spiking Neural Networks (SNNs) have emerged as a promising alternative to traditional Deep Neural Networks for low-power computing. However, the effectiveness of SNNs is not solely…

Low-Variance Forward Gradients using Direct Feedback Alignment and Momentum

Florian Bacho, Dominique Chu

Supervised learning in deep neural networks is commonly performed using error backpropagation. However, the sequential propagation of errors during the backward pass limits its sca…

Programming molecular systems to emulate a learning spiking neuron

Jakub Fil, Neil Dalchau, Dominique Chu

Hebbian theory seeks to explain how the neurons in the brain adapt to stimuli, to enable learning. An interesting feature of Hebbian learning is that it is an unsupervised method a…

Integrate-and-Fire Neurons for Low-Powered Pattern Recognition

Florian Bacho, Dominique Chu

Embedded systems acquire information about the real world from sensors and process it to make decisions and/or for transmission. In some situations, the relationship between the da…

Constraints on Hebbian and STDP learned weights of a spiking neuron

Dominique Chu, Huy Le Nguyen

We analyse mathematically the constraints on weights resulting from Hebbian and STDP learning rules applied to a spiking neuron with weight normalisation. In the case of pure Hebbi…

A thermodynamically consistent chemical spiking neuron capable of autonomous Hebbian learning

Jakub Fil, Dominique Chu

We propose a fully autonomous, thermodynamically consistent set of chemical reactions that implements a spiking neuron. This chemical neuron is able to learn input patterns in a He…

Minimal spiking neuron for solving multi-label classification tasks

Jakub Fil, Dominique Chu

The Multi-Spike Tempotron (MST) is a powerful single spiking neuron model that can solve complex supervised classification tasks. While powerful, it is also internally complex, com…

A thermodynamically consistent model of finite state machines

Dominique Chu, Richard Spinney

Finite state machines (FSMs) are a theoretically and practically important model of computation. We propose a general, thermodynamically consistent model of FSMs and characterise t…

Information ratchets exploiting spatially structured information reservoirs

Richard E. Spinney, Mikhail Prokopenko, Dominique Chu

Information ratchets extract work from heat baths using low entropy information reservoirs. We find that the structure of the reservoirs affects both their performance and phase di…

The thermodynamics of quasi-deterministic digital computers

Dominique Chu

It is now well established that there is no lower bound for the energy dissipated during a computation. The relevance of the zero-energy limit is unclear, however, because it entai…

Performance limits and trade-offs in entropy-driven biochemical computers

Dominique Chu

The properties and fundamental limits of chemical computers have recently attracted significant interest as a model of computation, an unifying principle of cellular organisation a…
