Transitions in echo index and dependence on input repetitions

no code implementations9 Sep 2023 Peter Ashwin, Andrea Ceni

Casting our theoretical findings in the RNN computing framework, we obtain that for small amplitude forcing the echo index corresponds to the number of attractors for the input-free system, while for large amplitude forcing, the echo index reduces to one.

Edge of stability echo state networks

no code implementations5 Aug 2023 Andrea Ceni, Claudio Gallicchio

With the goal of bringing together the fading memory property and the ability to retain as much memory as possible, in this paper we introduce a new ESN architecture, called the Edge of Stability Echo State Network (ES$^2$N).

Random orthogonal additive filters: a solution to the vanishing/exploding gradient of deep neural networks

no code implementations3 Oct 2022 Andrea Ceni

Since the recognition in the early nineties of the vanishing/exploding (V/E) gradient issue plaguing the training of neural networks (NNs), significant efforts have been exerted to overcome this obstacle.

Cross frequency coupling in next generation inhibitory neural mass models

no code implementations21 Aug 2019 Andrea Ceni, Simona Olmi, Alessandro Torcini, David Angulo-Garcia

Coupling among neural rhythms is one of the most important mechanisms at the basis of cognitive processes in the brain.

Interpreting recurrent neural networks behaviour via excitable network attractors

no code implementations27 Jul 2018 Andrea Ceni, Peter Ashwin, Lorenzo Livi

Simulations conducted on a controlled benchmark task confirm the relevance of these attractors for interpreting the behaviour of recurrent neural networks, at least for tasks that involve learning a finite number of stable states and transitions between them.
