Professor Ivan Tyukin

Professor of Applied Mathematics

Profile

Professor Ivan Tyukin is an expert in the mathematical foundations of Artificial Intelligence (AI) and learning systems, Machine Learning, mathematical modelling, adaptive systems, inverse problems with nonconvex and nonlinear parameterization, data analytics, and computer vision.

Professor Tyukin has been awarded a prestigious Turing AI Acceleration Fellowship to lead innovative and creative AI research with transformative impact. He is a member of the IFAC Technical Committee on Adaptive and Learning Systems, an Editor of Communications in Nonlinear Science and Numerical Simulations, and is a member of the All Party Parliamentary Group on AI's data governance task force which examines the economic, social, and ethical implications of AI. He has a broad network of academic and industrial collaborators includes strategic UK sectors such as public safety and security, health technologies, space and Earth Observation, and manufacturing.

Professor Tyukin’s recent work focuses on creating a theory and practice for developing AI systems that are provably robust, resilient, certifiable, trustworthy, human-centric and data-driven. The theory will enable the creation of new-generation AI systems which are certifiably stable, secure, adaptive and maintainable. These systems will be prepared to handle the challenges of adversarial attacks and data inconsistences, uncertainties, and bias inherent within any empirical data. This will enable new gold standard methods and tools in tasks that are currently heavily reliant upon non-deterministic human input to have long-term transformation.

Research

My long-term research interests revolve around challenges of creating theories, methods, and algorithms underpinning creation and understanding of machine intelligence, adaptation, and learning as well as helping to reveal their fundamental limitations. Development of these theoretical tools requires combination of techniques from different areas spanning concentration of measure theory, statistical learning theory, analysis, modelling and synthesis of fragile, nonlinear, chaotic, meta-stable dynamics, adaptation and adaptive control theory, synchronization (stable and critical), biologically-inspired systems for processing of the visual information, computer vision, networks of interconnected dynamical systems, analysis of dynamics of the spiking neuron models, their properties and possible functions, algorithms for machine learning and data analysis in high dimensions. For the sake of simplicity, I organized these different lines of inquiry into the following specific challenges I am addressing at the moment:

  1. Provably Resilient, Trustworthy, and Robust Artificial Intelligence. Discovering general principles and fundamental understanding of how to build certifiably safe, quantifiable, and trustworthy AI systems for the benefit of people.
  2. Machine Learning and Data Analysis in High dimensions. Exploiting measure concentration effects for development and analysis of efficient algorithms for machine learning and data analytics in high dimensions.
  3. Processes and Mechanisms of Adaptation in Complex Nonlinear Systems. Systems with nonlinear parametrization, unstable target dynamics, non-dominating (non-majorating, gentle, non-dominating) adaptation
  4. Synchronization in Nonlinear Dynamical Systems. Global, partial, intermittent  synchronization in the ensembles of linearly and nonlinearly  coupled nonlinear oscillators. Study of connectivity-dependent synchronization. Adaptive and unstable, multi-stable, alternating synchrony.
  5. Optimization algorithms for nonconvex and nonlinear problems. Parameter estimation and inverse problems involving systems of ordinary differential equations with nonlinear in parameter right-hand side.
  6. Analysis of dynamical systems with unstable and semi-stable attractors. Extension of the method of Lyapunov functions for systems with weakly attracting  (in Milnor sense) invariant sets, first method of Lyapunov for non-hyperbolic equilibria, non-uniform small-gain theorems.
  7. Neuroscience and physics of neuronal cells. Principles of neuronal processing of  information. Study of properties of the biological cells, analysis of their functions. Structural organization of the visual system, models system for robust  and adaptive processing (w.r.t modelled uncertainties) of visual information.
