Blob interaction in 2D scrape off layer simulations
Gregor Decristoforo, Fulvio Militello, Odd Erik Garcia +4
Interaction of coherent structures known as blobs in the scrape-off layer of magnetic confinement fusion devices is investigated. Isolated and interacting seeded blobs as well as f…
Optimization with delay-induced bifurcations
Natalia B. Janson, Christopher J. Marsden
Optimization is finding the best solution, which mathematically amounts to locating the global minimum of some cost function. Optimization is traditionally automated with digital o…
Delay-induced homoclinic bifurcations in modified gradient bistable systems and their relevance to optimisation
Natalia B. Janson, Christopher J. Marsden
Nonlinear dynamical systems with time delay are abundant in applications, but are notoriously difficult to analyse and predict because delay-induced effects strongly depend on the…
Conceptual model of a cognitive system: dynamical system with plastic self-organizing velocity field
Natalia B. Janson, Christopher J. Marsden
Spontaneously evolving living systems can be modelled as continuous-time dynamical systems (DSs), whose evolution rules are determined by their velocity vector fields. We point out…
Self-shaping dynamical systems and learning
Natalia B. Janson, Christopher J. Marsden
We associate learning and adaptation in living systems with the shaping of the velocity vector field in the respective dynamical systems in response to external, generally random,…
"Memory foam" approach to unsupervised learning
Natalia B. Janson, Christopher J. Marsden
We propose an alternative approach to construct an artificial learning system, which naturally learns in an unsupervised manner. Its mathematical prototype is a dynamical system, w…
