Neuromorphic computing is at the forefront of machine learning research, aiming to tackle the ever growing energy consumption of modern AI applications. By using physical systems as a 'reservoir' data can be transformed to a representation that is easier to classify or predict in an energy efficient manner.
About the Supervisor
Dr Ellis' research focused on developing energy efficient machine learning algorithms and systems based on neuromorphic computing. In particular, he is interested in developing models of physical systems that can be utilised as machine learning processing devices, such as devices for physical reservoir computing or neuromorphic hardware based on magnetic systems.
This project aims to develop novel approaches for physical reservoir computing and it will explore the theoretical framework of advanced read-out, training and connectivity methods for spintronic reservoirs. Recent advances in reservoir computing with our group has highlighted the power of sparse output methods (https://arxiv.org/abs/1912.08124) and connecting multiple reservoirs for tasks with multiple timescales (https://arxiv.org/abs/2101.04223) but their application to physical reservoir systems has not been proven. This project will study these techniques applied to models of magnetic reservoirs with a view to apply these to state-of-the-art machine learning tasks to demonstrate the potential of reservoir computing in real life. To aid the development of these techniques it may be necessary to develop neural ODE models of the physical reservoirs to reduce the computational complexity of the physical models.
