报告摘要：Several techniques for wireless networking, such as opportunistic spectrum access, or self-healing networks, may be seen as using a form of cognition, meaning that they mimic reasoning processes of intelligent beings. We propose to expand this cognition-based process by exploiting the parallel processing power of the infrastructure, so as to go beyond cognition as is meant by these approaches. We leverage novel approaches, taken from cognitive science and artificial intelligence, involving not only supervised but also unsupervised learning (including deep learning), and we envision their application to wireless systems. For a wireless scenario, we propose and evaluate a video classifier based on a Restricted Boltzmann Machine that tries to extract abstract features of videos from the analysis of the sizes of a few coded frames, that can then be exploited by the communication network to optimize video transmission based on its content. We will also describe a testbed that we recently developed at the University of Padova for cognition-based research, which employs cheap commercial devices and can be easily replicated.
