Abstract：

Acoustic sensing and communication are increasingly popular owing to widely available devices that support them. Yet the sensing resolution and communication range are still limited due to limited bandwidth and sharp decay in the signal at inaudible frequencies. In this talk, I will present a novel acoustic system that leverages a low-cost metasurface to significantly enhance SNR, acoustic sensing accuracy, and acoustic communication reliability over a wide range of scenarios.

Abstract：

Decision-making problems are ubiquitous in computer systems. Examples include cluster resource management and cloud service configuration, to name a few. These decision-making tasks are usually performed online, and the results critically determine the system performance and operational cost. As systems grow increasingly larger, these tasks become too complex to model accurately and are usually solved by heuristics that require manual testing and tuning in practice. In recent years, using machine learning as an alternative to human-generated heuristics for decision making has gained significant momentum in complex systems. Through techniques like reinforcement learning and meta learning, systems can now learn to make superior decisions from experience interacting with the environment. However, it is important to recognize that machine learning is not a panacea for all decision-making tasks. In this talk, I will present our recent efforts in pursuit of this vision and share our experiences in deploying them in real systems, including the good, the bad, and the ugly.

LI Bo is a Chair Professor in the Department of Computer Science and Engineering, Hong Kong University of Science and Technology, where he has been affiliated with since 1996. He holds the Cheung Kong Chair Professor in Shanghai Jiao Tong University. He is a Fellow of IEEE for "contribution to content distributions via the Internet". He received the Young Investigator Award from the National Natural Science Foundation of China (NSFC) in 2005. He served as a Distinguished Lecturer for IEEE Communications Society (2006-2007). He was a co-recipient for three Best Paper Awards from IEEE, and the Best System Track Paper in ACM Multimedia (2009). He made original contributions on the proxy placement for content distribution networks (CDNs), in which his IEEE INFOCOM (1999) paper "On the Optimal Placement of Web Proxies in the Internet" was the first work addressing this problem. He made pioneering contributions in large-scale Peer-to-Peer live video streaming; specifically, the system, Coolstreaming (2004-2005) (Google entries over 2,000,000) was credited as the first large-scale Peer-to-Peer live video streaming system in the world. This work appeared in IEEE INFOCOM (2005) has not only been highly cited, but also spearheaded a momentum in peer-to-peer streaming, with no fewer than a dozen successful companies such as PPLive, PPStream, UUSee and YahooBB (Japan) adopting the same mesh-based pull streaming technique to deliver live media content to millions of users. He also led a team developing a real-world peer-assisted online hosting system, FS2You (2007-2008) (Google.cn entries over 4,000,000 in 2009) that has attracted millions of downloads worldwide.
