Abstract: Many IoT applications demand intelligent decisions in a real-time manner. The necessity of real-time edge intelligence dictates that decision making takes place right here right now at the network edge. Since an edge node often has a limited amount of data and is constrained with computational resources, we advocate continual edge learning to achieve edge intelligence. To this end, we develop an edge learning framework where the edge node learns its model based on local data in real-time, while leveraging the cloud knowledge transfer or learning from peer edge nodes.

Abstract: Modern machine learning systems are susceptible to adversarial examples; inputs that preserve the characteristic semantics of a given class, but whose classification is incorrect. Current approaches to defense against adversarial attacks rely on modifications to the input (e.g. quantization, randomization) or to the learned model parameters (e.g. via adversarial training), but are not always successful. This talk will include: 1) Overview of attacks on machine learning and defenses. 2) Discussion of the enablers of successful adversarial attacks via theory, and empirical analysis of commonly used datasets. 3) Discussion of recently proposed defenses that change the representation of the model outputs, drawing upon insights from coding theory. 4) Novel approaches to detection of adversarial examples using confidence metrics. The talk will conclude with a discussion of issues in distributed ML in coalition operations.

Abstract: In this talk, we introduce a new wireless research paradigm by employing a massive number of low-cost passive reflecting elements with controllable phase, named intelligent reflecting surface (IRS), which is able to smartly change the wireless signal propagation to enable various functions such as beamforming and interference nulling/cancelation. We illustrate the main applications of IRS in achieving spectrum and energy efficient as well as secure and sustainable wireless networks in the future, and its advantages as compared to existing technologies such as massive MIMO and active relaying. We then present the signal and channel model of IRS by taking into account its hardware limitation in practice. Next, we focus on discussing the main design challenges in IRS-aided wireless networks, including joint active and passive beamforming optimization, channel estimation, etc., and highlight important directions for future work.

Abstract: Voice access technologies are widely adopted in mobile and voice assistant systems at the edge to serve as both critical and convenient ways for user interaction. Recent studies have demonstrated various vulnerabilities of voice assistant systems. One serious attack is to use synthetically rendered adversarial sounds embedded within a voice command to trick the speech recognition process into executing malicious commands, without being noticed by legitimate users. We show that by employing low-cost motion sensors, in a novel way, to detect these hidden voice commands. Our approach is based on the premise that while the crafted audio features of the hidden voice commands may fool an authentication system in the audio domain, their unique audio-induced surface vibrations captured by the motion sensor are hard to forge. Our approach extracts and examines the unique audio signatures of the issued voice commands in the vibration domain to detect the presence of hidden voice attacks. We further show that speech/speaker recognition systems are vulnerable to adversarial attacks. In particular, we demonstrate that we could successfully launch over-the-air adversarial attacks to the state-of-the-art deep neural network (DNN) based speaker recognition system in practical scenarios. In such scenarios, the adversarial examples are played through a loudspeaker to compromise speaker recognition devices.
