Keynote Talk Title: Security of 4G and 5G cellular networks
Time: 8:30-9:30, Wednesday, February 19, 2020

As the world moves to 4G and 5G cellular networks, security and privacy are paramount importance and new tools are needed to ensure them. For example, LTEInspector is a model-based testing approach that combines a symbolic model checker and a cryptographic protocol verifier in the symbolic attacker model. Using it, researchers have uncovered 10 new attacks along with 9 prior attacks, categorized into three abstract classes (i.e., security, user privacy, and disruption of service), in three procedures of 4G LTE. Notable among the findings is the authentication relay attack that enables an adversary to spoof the location of a legitimate user to the core network without possessing appropriate credentials. To ensure that the exposed attacks pose real threats and are indeed realizable in practice, 8 of the 10 new attacks have been validated and their accompanying adversarial assumptions have been put through a real testbed. On-going work in addressing some of those vulnerabilities points the way toward an agenda of further research.

Keynote Talk Title: Reinforcement Learning for Resource Management in Space-Air-Ground (SAG) Integrated Vehicular Networks
Time: 8:30-9:30, Thursday, February 20, 2020

Space-Air-Ground integrated Vehicular Network (SAGVN) is a prominent paradigm to provide an extremely versatile vehicular network that can simultaneously guarantee ultra-reliability low-latency communications (URLLC) and deliver high-bandwidth traffic anywhere, any environment condition, and any event at anytime. However, it is challenging to manage and allocate the terrestrial network, aerial network (UAV), and space (satellite) resources simultaneously and efficiently, as they have heterogeneous access features in terms of delay, throughput, and coverage range. In addition, high vehicle mobility and real-time decision requirement further render the problem intractable. In this talk, we advocate the usage of reinforcement learning for resource management in SAGVN, which can enable model-free and fast decision makings for adaptive access control, on-demand UAV deployment, and UAV trajectory design. We will also show the detail development of our SAG simulator and some demos.

Keynote Talk Title: Safe Learning in Robotics
Time: 10:00-11:00, Monday, February 18, 2019

A great deal of research in recent years has focused on robot learning. In many applications, guarantees that specifications are satisfied throughout the learning process are paramount. For the safety specification, we present a controller synthesis technique based on the computation of reachable sets, using optimal control and game theory. In the first part of the talk, we will review these methods and their application to collision avoidance and avionics design in air traffic management systems, and networks of unmanned aerial vehicles. In the second part, we will present a toolbox of methods combining reachability with data-driven techniques inspired by machine learning, to enable performance improvement while maintaining safety. We will illustrate these “safe learning” methods on robotic platforms at Berkeley, including demonstrations of motion planning around people, and navigating in a priori unknown environments.

Keynote Talk Title: Challenges and Opportunities in Algorithmic Solutions for Re-Balancing in Bike Sharing Systems
Time: 8:30-9:30, Tuesday, February 18, 2020

In recent years, the booming of the bike sharing system (BSS) has played an important role in offering a convenient means of public transport. The BSS is also viewed as a solution to the first/last mile connection issue in urban cities. The BSS can be classified into dock and dock-less. However, due to imbalance in bike usage over spatial and temporal domains, stations in the BSS may exhibit overflow (full stations) or underflow (empty stations). In this talk, we will take a holistic view of the BSS design by examining the following four components: (1) system design, (2) system prediction, (3) system balancing, and (4) trip advisor. We will focus on system balancing, addressing the issue of overflow/underflow. We will look at two main methods of bike rebalancing: with trucks and with workers. Discussion on the other three components that are related to system balancing will also be given. Specifically, we will study various algorithmic solutions with the availability of data in spacial and temporal domains. Finally, we will discuss several key challenges and opportunities of the BSS design and applications as well as the future of dock and dock-less BSS in a bigger setting of the transportation system.

Specially Appointed Professor for Research, Tohoku University, Japan

Plenary Title: Ultra-dense Radio Access Network for 5G Advanced Systems
Time: 13:30-14:30, Tuesday, February 18, 2020

Restructuring the radio access network (RAN) is inevitable to support a huge number of users or devices requiring high data rate, high reliability, and low latency. One promising architecture is ultra-dense RAN consisting of large-scale distributed multiple-input multiple-output (MIMO) and mobile edge computing (MEC). The biggest challenge is the prohibitively high computational complexity required to handle large numbers of distributed antennas (DAs) and user equipments (UEs) for large-scale distributed MIMO cooperative transmission and reception. This computational complexity problem can be alleviated by introducing location-based user clustering to form a number of user-centric virtual cells (VCs). However, since the same radio resource needs to be densely reused to improve the spectrum efficiency, two types of interference arise: inter-VC interference (IVCI) in each RAN area and inter-cell interference (ICI) from neighboring eRAN areas. In this talk, we will present promising approaches for mitigating the interference problems. In order to mitigate the IVCI problem, joint UE or DA clustering and scheduling is introduced. Furthermore, to mitigate the ICI problem, decentralized learning-based adaptive ICI coordination (ICIC) is introduced, which is based on the fractional frequency reuse (FFR) concept. By introducing the above interference mitigation techniques, highly flexible and scalable deployment of ultra-dense RANs having high capacity and low latency can be realized.

Plenary Title: Machine Learning Techniques for Fast Protocol Adaptation in Wireless Networks
Time: 13:30-14:30, Wednesday, February 19, 2020

Classical techniques for protocol adaptation and interference mitigation in wireless networks often rely on static policies, designed based on a priori assumptions of the underlying dynamics (e.g., channel models, node distributions, etc.). These techniques are too idealized for realistic deployment scenarios, as they fail to capture the broad range of control parameters that impact network performance, especially in situations involving coexistence of heterogeneous technologies. Machine learning (ML) techniques, on the other hand, can capture a wide range of control parameters (features), with no or minimal assumptions about the underlying dynamics. However, such ML techniques emphasize performance over time complexity, rendering them unsuitable for real-time adaptation. In this talk, we will explore this performance/complexity tradeoff and present various ML techniques that are geared towards real-time protocol adaptation for specific wireless systems, including CSMA-based protocols at mid bands (e.g., Wi-Fi and LTE LAA) as well as multi-antenna/beamforming systems at high (millimeter-wave) bands. Hybrid adaptation techniques that combine model-free ML techniques (“black box”) with robust and highly generic modeling assumptions will also be discussed.

Plenary Title: Federated Learning: Challenges and Opportunities
Time: 14:30-15:30, Wednesday, February 19, 2020

In the era of Internet of Things, edge computing, and Big Data, large volumes of data has been generated by millions of mobile devices and sensors at the edge of the Internet on a daily basis. Resolving the conflict between the need for analyzing such data and the requirements for preserving user privacy has always been a balancing act. Federated learning, as a new distributed computing paradigm involving both the edge and the cloud, has been touted in the recent years as a way to achieve a balanced tradeoff between utilizing data and preserving data privacy. It offers us the best of both worlds: privacy-preserving training of machine learning models. Yet, by performing local training and collecting model updates from edge devices, federated learning incurred a large amount of communication overhead, and has to address the problems of systems and statistical heterogeneity. In this talk, we explore the current challenges and opportunities in federated learning, and then present our recent work related to statistical heterogeneity. Throughout the talk, we will present an outlook on opportunities for future research.
