Noise Optimization for Artificial Neural Networks
CoRR, 2021 Se ha demostrado que la adición de ruidos a la red neuronal artificial (ANN) puede mejorar la solidez en trabajos anteriores. En este trabajo, proponemos una nueva técnica para calcular la estimación del gradiente estocástico Pathwise con respecto a la desviación estándar del ruido gaussiano añadido a cada neurona de la ANN.

Large-Scale Multicast Group Secure Transmission Scheme Based on Multi-Carrier FDA
Sensors, 2023 Aiming at the problem that the traditional physical layer technology cannot realize secure transmission due to the large number of users and wide dispersion in the multicast system, a layered transmission method is proposed, and a scheme for the secure ...

Antenna Grouping-Based Blind Artificial Noise for TDD Secure Transmission
IEEE Access, 2021 The artificial noise (AN-) aided techniques have been considered as promising candidates to enhance the physical layer security. However, the effect of AN on an eavesdropper (Eve) can be severely degraded as the number of antennas at Eve increases.

Noise-induced artificial intelligence
Physical Review Research, 2022 We show that unavoidable stochastic fluctuations are not only affecting information processing in a destructive or constructive way, but may even induce conditions necessary for the artificial intelligence itself. In this proof-of-principle paper we consider a model of a neuron-astrocyte network under the influence of multiplicative noise and show that

Secrecy Performance of a Multi-NOMA-MIMO System in the UEH Relaying Network Using the PSO Algorithm
IEEE Access, 2021 In this paper, we investigate the secrecy performance of the nonorthogonal multiple access (NOMA) system in an untrusted relaying energy harvesting (UEH) network with the multiple-input multiple-output (MIMO) architecture using the maximum ratio ...

Artificial Noise Aided Secure Transmission for Active RIS-Aided NOMA Networks
IEEE Access, 2023 A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper. Assuming that the perfect channel state information is available, we aim to maximize the

Secure MISO-NOMA Transmission With Artificial Noise [PDF]
IEEE Transactions on Vehicular Technology, 2018 This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the proposed SBF scheme efficiently exploits artificial noise to protect the confidential information of two NOMA assisted legitimate users, such that only the eavesdropper's channel is ...
