On the 18th of June, 2021 the UNIPI team has participated in the International Work-Conference on Artificial Neural Networks (IWANN 2021) conference. IWANN 2021 is one of the most important events that pursues to provide a discussion forum for scientists, engineers, educators and students about the latest ideas and realizations in the foundations, theory, models and applications of systems inspired by nature (neural networks, fuzzy logic and evolutionary systems) as well as in emerging areas related to the Artificial Neural Networks. During the event, Daniele Di Sarli had the opportunity to present the research work with the title “Benchmarking Reservoir and Recurrent Neural Networks for Human State and Activity Recognition”.
