Michal Valko : Regularity counting


Plastic Synapses project is about modelling basice learning function at the level of synapses. Our objective is to design model that is able to adapt to regular frequencies with different rate as the time flows. During the research, we proposed many different models and validated their behavior and biological plausibility.
