Disponível em: https://repositorio.ipen.br/handle/123456789/49289.https://repositorio.ipen.br/handle/123456789/49289This work shows a ReLU-like activation function generated by the emission of a Nd:YVO random laser. The emission response was fitted and implemented as a custom activation function in a neural network trained on the MNIST dataset, achieving an accuracy of 96%. This indicates the potential of random lasers as optical activations for future optical neural network architectures.engclosedAccessTexto completo de evento10.1109/SBFotonIOPC66433.2025.11218538https://orcid.org/0000-0002-9379-9530
