Non-negative isomorphic neural networks for photonic neuromorphic accelerators

no code implementations2 Oct 2023 Manos Kirtas, Nikolaos Passalis, Nikolaos Pleros, Anastasios Tefas

To this end, we introduce a methodology to obtain the non-negative isomorphic equivalents of regular neural networks that meet requirements of neuromorphic hardware, overcoming the aforementioned limitations.

Multiplicative update rules for accelerating deep learning training and increasing robustness

no code implementations14 Jul 2023 Manos Kirtas, Nikolaos Passalis, Anastasios Tefas

We claim that the proposed framework accelerates training, while leading to more robust models in contrast to traditionally used additive update rule and we experimentally demonstrate their effectiveness in a wide range of task and optimization methods.
