Download e-book for iPad: Models of Wave Memory by Serguey Kashchenko

This monograph examines intimately versions of neural structures defined through delay-differential equations. each one component to the medium (neuron) is an oscillator that generates, in standalone mode, brief impulses often referred to as spikes. The e-book discusses versions of synaptic interplay among neurons, which bring about advanced oscillatory modes within the process.

In (5), d [n] represents the desired signal for the nonlinear model. Being wFL,n a conventional linear filter, it can be adapted by any adaptive algorithm based on the minimization of the mean square error [20]. The use of an adaptive filter after the expansion allows to apply the FLAF model to several online learning applications, such as active noise reduction, acoustic echo cancellation [19,2,17,3].

By considering the three experiments above, it is worth noting that the proposed MPNLMS-FLAF achieves an improvement as large as higher the nonlinearity degree. This is due to the fact that a strong nonlinearity needs a larger expansion buffer, whose effectiveness of the nonlinear elements is not uniform but sparse. Moreover, it can be noticed that, unlike the MPNLMS-FLAF, the NLMS-FLAF considers also the useless functional links, which generates overfitting. Therefore, we can conclude that the performance gap of the NLMS-FLAF from the proposed MPNLMS-FLAF is essentially due to the overfitting.

This means that, together with an increase in performance, the ESN is also faster to train, and easier to eventually implement on an hardware platform.
