Lecture title: “Sound as an Exteroceptive and Proprioceptive Sensing Modality for Autonomous Driving”.

Abstract: Can the automatic detection and interpretation of acoustic events ease autonomous driving? What monitoring and modelling the ego-noise of an autonomous vehicle can tell us about the
environment and the status of the vehicle?

Starting from specific use-cases, we will investigate the crucial role that sound analysis can play in autonomous driving, exploring state-of-the-art methods and techniques in machine learning which allow an autonomous system to robustly operate also in harsh noisy conditions. We will delve into different feature representations of audio signals, evaluating benefits and disadvantages with respect to the task at hand. We will discuss less traditional approaches to noise removal to cope with environments characterised by really low Signal-to-Noise Ratios (SNRs). Lastly, we will examine the possibility of considering noise, not as an unwanted masking signal in the auditory data we wish to analyse and understand, but rather, as an opportunity to learn valuable information about the environment and the behaviour of an autonomous vehicle.
