It is an exciting time as machine learning (ML) techniques, based on signal processing (SP) and other disciplines, are enabling us to solve a wide range of challenging and valuable problems. In this talk I will share how we are applying ML to improve networked applications, such as interactive video communications and emerging multi-user AR/VR, and networked systems, such as Internet of Things (IoT) systems. A key theme in this talk is to show, via examples, how a modern network provides new sources of data that enables SP and ML experts to solve a diverse set of important problems.

This talk will examine how machine learning (ML) benefits networked systems by highlighting four examples. First, we will examine Intent-Based Networking (a modern architecture for designing and operating a network) and how ML can be used to increase visibility, diagnose problems and identify associated remedies, and provide assurance on application performance. Next, we’ll examine how to understand what devices are connected to the network, which is a key step to providing customized network performance and protecting those devices. In the context of ever-growing security threats, we’ll examine how ML can be applied to address the challenge of detecting malware sneaking in an encrypted flow without requiring decryption of those flows. Lastly, we’ll look at the move from today’s Cloud-based ML to the promising approach of Distributed ML across Edge and Cloud that can lead to improved scalability, reduced latency, and improved privacy for multimedia applications. It is noteworthy that while ML often raises privacy concerns, the last two examples showcase how an elegant application of ML can achieve the desired goal while preserving privacy.


John Apostolopoulos is VP/CTO of Cisco’s Enterprise Networking Business (Cisco’s largest business) where his work includes wireless (from Wi-Fi 6 to 5G), Internet of Things, multimedia networking, visual analytics, and ML and AI applied to the aforementioned areas. Previously, John was Lab Director for the Mobile & Immersive Experience (MIX) Lab at HP Labs. The MIX Lab conducted research on novel mobile devices and sensing, mobile client/cloud multimedia computing, immersive environments, video & audio signal processing, computer vision & graphics, multimedia networking, glasses-free 3D, wireless, and user experience design. John is an IEEE Fellow, IEEE SPS Distinguished Lecturer, named “one of the world’s top 100 young innovators” by MIT Technology Review, contributed to the US Digital TV Standard (Engineering Emmy Award), and his work on media transcoding in the middle of a network while preserving end-to-end security (secure transcoding) was adopted in the JPSEC standard. He published over 100 papers, receiving 5 best paper awards, and about 80 granted US patents. John was a Consulting Associate Professor of EE at Stanford. He received his B.S., M.S., and Ph.D. from MIT.
