Virtual Seminar by Husheng Li

Title: The Art of Marriage: How to Integrate Data Communications and Radar Sensing?

Time and Date: Monday, Apr. 29, 2024, 9:00am US Eastern Time (New York Time)

Presenter: Dr. Husheng Li, Purdue University

Venue: https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: Integrated Sensing and Communications (ISAC), are expected to be a featuring technology in 6G wireless communication networks. It improves the efficiencies of spectrum and energy by sharing the same waveform for both tasks of communications and sensing. The waveform in ISAC could be traditional communication waveforms (such as OFDM) or existing radar waveforms (such as FMCW). In this talk, we will discuss waveform design dedicated for ISAC, which may go beyond existing waveform designs for individual systems. We focus on two questions, for the marriage of communications and sensing: (a) How to design a natural and enlightening framework for integrating both communications and sensing? To this end, we propose to consider ISAC as a broadcast and thus unify several major designs within the same framework. (b) How to characterize the conflict and trade-off between communications and sensing when they are integrated within the same waveform? We will examine several types of conflict, such as randomness-determinism, environmental complexity, and coding-spreading trade-offs. Finally, I will provide an overview on my future research in the area of ISAC.

Virtual Seminar by Yu Wang

Title: Learning Scheduling and Optimization in Federated Edge Learning

Time and Date: Tuesday, Nov. 14, 2023, 9:00AM US Eastern Time (New York Time)

Presenter: Dr. Yu Wang, Professor in the Department of Computer and Information Sciences, Temple University, Philadelphia, Pennsylvania 19122, USA

Venue: https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: Edge computing and federated learning (FL) have gained popularity since they provide a promising edge learning framework that mitigates the limitations of long latency, high cost, and privacy concerns in cloud-based centralized learning. While most existing works on federated edge learning focus on optimizing the training of the global model in edge systems, the concurrent training of multiple FL models from different applications in a shared edge cloud can lead to edge resource competition and affect the training performance of each model. Hence, in this talk, I will present our recent works in addressing this challenge by proposing optimization algorithms to jointly select FL participants and learning rates or topologies for each model, with an aim of minimizing the total training cost. Particularly, I will first introduce a multi-stage optimization framework that allows FL models to select their participants and learning rates or learning topologies. Then, I will describe a quantum assisted algorithm to tackle the joint participant selection and learning scheduling problem using both quantum and classical computing. Finally, I will summarize the talk with discussions about future directions in federated edge learning.

Virtual Seminar by Nan Cheng

Title: RingSFL: An Adaptive Split Federated Learning Towards Taming Client Heterogeneity Date and Time:  Sept. 1, 2023, 9:00 am – 10:00 am US Eastern Time (New York Time) Zoom Link: https://us04web.zoom.us/j/76618091026?pwd=bSR2dziIyZUS0aWF2R666BJEl4pMS5.1 Abstract:  Federated learning (FL) has gained increasing attention due to its ability to collaboratively train while protecting client data privacy. However, in most wireless networks, such as vehicular networks, client heterogeneity exists, as different vehicular users have different computation capabilities. Vanilla FL cannot handle client heterogeneity, leading to a degradation in training efficiency due to stragglers, and is still vulnerable to privacy leakage. To address these issues, we propose RingSFL, a novel distributed learning scheme that integrates FL with a model split mechanism to adapt to client heterogeneity while maintaining data privacy. In RingSFL, all clients form a ring topology. For each client, instead of training the model locally, the model is split and trained among all clients along the ring through a pre-defined direction. By properly setting the propagation lengths of heterogeneous clients, the straggler effect is mitigated, and the training efficiency of the system is significantly enhanced. Additionally, since the local models is blended, it is less likely for an eavesdropper to obtain the complete model and recover the raw data, thus improving data privacy. The experimental results on both simulation and prototype systems show that RingSFL can achieve better convergence performance than benchmark methods on independently identically distributed (IID) and non-IID datasets, while effectively preventing eavesdroppers from recovering training data.

Virtual Seminar by Jie Wu

Title: On Optimal Partitioning and Scheduling of DNNs in Mobile Edge/Cloud Computing

Time and Date: Friday, July 21, 2023, 9:00am US Eastern Time (New York Time)

Presenter:  Dr. Jie Wu, Director of the Center for Networked Computing and Laura H. Carnell professor, Temple University, USA

Venue: https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: As Deep Neural Networks (DNNs) have been widely used in various applications, including computer vision on image segmentation and recognition, it is important to reduce the makespan of DNN inference computation, especially when running on mobile devices. Offloading is a viable solution that offloads computation from a slow mobile device to a fast, but remote edge/cloud. As DNN computation consists of a multiple-stage processing pipeline, it is critical to decide on what stage should offloading occur to minimize the makespan. Our observations show that the local computation time on a mobile device follows a linear increasing function, while the offloading time on a mobile device is monotonic decreasing and follows a convex curve as more DNN layers are computed in the mobile device. Based on this observation, we first study the optimal partition and scheduling for one line-structure DNN. Then, we extend the result to multiple line-structure DNNs. Heuristic results for general-structure DNNs, represented by Directed Acyclic Graphs (DAGs), are also elaborated based on a path-based scheduling policy. Extensions to DNN training are also discussed.

Title: On Communication and Sensing Measurements and Modeling for Next “G”

Presenter:  Dr. Nada T. Golmie, National Institute of Standards and Technology, USA

Venue: https://zoom.us/j/9172542706 (Password: 4Zn7xZ)

Abstract: As the needs for sensing the physical world to support detection, tracking, AR/VR and slew of other applications increase, the use of communications waveforms for sensing is attracting a lot of attention and is likely to emerge as one of the main features in NextG development.
In this talk we discuss key challenges in measurement science and modeling approaches for advanced communications and sensing going forward. We will review the main building blocks for joint communications and sensing in terms of efficient spectrum use, higher frequency bands and the use machine learning. The millimeter-wave and terahertz bands hold the promise of significant bandwidth and speed due to large swaths of untapped spectrum. In addition, as massive data volumes are being collected, analyzed, and delivered, communications systems have become too complex to develop, manage, and operate. The insights that are “mined” from the data using Machine Learning (ML) techniques have become standard practice. In this talk, we discuss state -of -the art and key challenges in measurement and modeling techniques to expedite the development and pave the way for the next “G”.

Abstract: This talk will provide an overview of ways in which machine learning and data-driven signal processing are impacting wireless sensing systems, spectrum anomaly-detection and analytic systems, and leading to powerful spectrum awareness capabilities which help to provide security, monitoring, and adaptation tools never previously possible at scale in wireless systems.
