Emerging Network Structures and Neuromorphic Applications

Project description

Towards novel neuromorphic applications

Neuromorphic computing emulates the way neural networks in the brain dynamically rewire to make decisions in response to particular stimuli. It uses new algorithmic approaches to improve the power and performance of the next generation of computers, as well as providing them with unprecedented capabilities. The EU-funded NEUROMORPH project aims to develop mathematical models and innovative numerical methods by combining concepts from thermodynamics, cell biology and electrical engineering. Researchers will generate models that recapitulate synapse behaviour and neuronal connectivity. Collectively, the work is expected to lead to novel memristor devices for ultra-dense electronics capable of storing, learning and handling Big Data.

Objective

Network structures arise in many applications like for biological tissues, neuron systems, and nanoelectronic devices. Neuronal network structures are inspiring novel neuromorphic computer architectures, overcoming physical scaling limits in traditional hardware. The project NEUROMORPH focuses on the interplay of emerging structures in biological neuron systems and electronic circuit models. The problems we address are formulated in terms of nonlinear partial differential systems, including stochastic and nonlocal terms. Examples include transport through ion channels, chemotaxis-fluid systems, mean-field network models, and memristor networks.
The aims of this mathematics-oriented project are to explore the structure of the multiscale systems, prove their well-posedness, and devise structure-preserving numerical methods. Mathematical challenges are coming from the cross-diffusion character, the coupling of different types of equations (partially diffusive, stochastic, algebraic), the nonstandard degeneracies of the equations, and the hierarchy of scales, ranging from the molecular to the cellular to the network level.
To achieve these goals, we develop new tools by combining variants of the boundedness-by-entropy method, compensated compactness, stability theory, and stochastic analysis. We build on the expertise of the PI on semiconductor device modeling, theory of cross-diffusion systems, numerical analysis, and recent work on stochastic differential equations. Concepts from thermodynamics, cell biology, and electrical engineering will be condensed into innovative mathematical theories for cross-diffusion systems and multiscale models.
The project culminates in the simulation of small bio-inspired neuromorphic circuits, where memristor devices model the behavior of synapses or ion channels and mimic neuronal connectivity. The combination of bio-physical and device-circuit models is expected to make a vital progress for the design of neuromorphic structures.
