IT Forum: From Gaussian Multiterminal Source Coding to Distributed Karhunen–Loève Transform

Topic: 
From Gaussian Multiterminal Source Coding to Distributed Karhunen–Loève Transform
Abstract / Description: 

Characterizing the rate-distortion region of Gaussian multiterminal source coding is a longstanding open problem in network information theory. In this talk, I will show how to obtain new conclusive results for this problem using nonlinear analysis and convex relaxation techniques. A byproduct of this line of research is an efficient algorithm for determining the optimal distributed Karhunen–Loève transform in the high-resolution regime, which partially settles a question posed by Gastpar, Dragotti, and Vetterli. I will also introduce a generalized version of the Gaussian multiterminal source coding problem where the source-encoder connections can be arbitrary. It will be demonstrated that probabilistic graphical models offer an ideal mathematical language for describing how the performance limit of a generalized Gaussian multiterminal source coding system depends on its topology, and more generally they can serve as the long-sought platform for systematically integrating the existing achievability schemes and converse arguments. The architectural implication of our work for low-latency lossy source coding will also be discussed.

This talk is based on joint work with Jia Wang, Farrokh Etezadi, and Ashish Khisti.


The Information Theory Forum (IT-Forum) at Stanford ISL is an interdisciplinary academic forum which focuses on mathematical aspects of information processing. With a primary emphasis on information theory, we also welcome researchers from signal processing, learning and statistical inference, control and optimization to deliver talks at our forum. We also warmly welcome industrial affiliates in the above fields. The forum is typically held in Packard 202 every Friday at 1:15 pm during the academic year.

The Information Theory Forum is organized by graduate students Jiantao Jiao and Yanjun Han. To suggest speakers, please contact any of the students.

Topic: 
The future of low power circuits and embedded intelligence: emerging devices and new design paradigms
Abstract / Description: 

Circuit and design division at CEA LETI is focusing on innovative architectures and circuits dedicated to digital, imagers, wireless, sensors, power management and embedded software. After a brief overview of adaptive circuits for low power multi-processors and IoT architectures, the talk will detail new technologies opportunities for more flexibility. Digital and mixed-signal architectures using 3D technologies will be presented in the scope of multi-processors activity as well as imagers and neuro-inspired circuits. Also, the integration of non-volatile memories will be shown in the perspective of new architectures for computing. Finally, embedding learning will be addressed to solve power challenges at the edge and in end-devices: some new design approaches will be discussed.

EE380 Computer Systems Colloquium: The Future of Wireless Communications Hint: It's not a linear amplifier

Topic: 
The Future of Wireless Communications Hint: It's not a linear amplifier
Abstract / Description: 

Wireless communications are ubiquitous in the 21 st century--we use them to read the newspaper, talk to our colleagues or children, watch sporting events or other forms of entertainment, and to monitor and control the environment we live ins-- among just a few. This exponentiation of demand for wireless capacity has driven a new era of innovation in this space because spectrum and energy are expensive and constrained resources.

The future of wireless communications will demand leaps in spectrum efficiency, bandwidth efficiency, and power efficiency for successful technology deployments. Key applications that will fundamentally change how we interact with wireless systems and the demands we place on wireless technologies include Dynamic Spectrum Access Networks, massive MIMO, and the evasive unicorn of the "universal handset". While each of these breakthrough "system" capabilities make simultaneous demands of spectrum efficiency, bandwidth efficiency, and power efficiency, the current suite of legacy technologies forces system designers to make undesirable trade-offs because of the limitations of linear amplifier technology.

Eridan's solution is the antithesis of "linear". The Switch Mode Mixer Modulator (SMs3 ) technology emphasizes precision and flexibility, and simultaneously delivers spectrum efficiency, bandwidth efficiency, and power efficiency. The resulting capabilities dramatically increase total wireless capacity with minimum need for expanding operations into extended regions of the wireless spectrum.

This presentation will discuss the driving forces behind wireless system performance, the physics of linear amplifiers and SM3, measured performance of SM3 systems, and the implications for wireless system capabilities in the near future.

EE380 Computer Systems Colloquium: Computer Accessibility

Topic: 
Exploring the implications of machine learning for people with cognitive disabilities
Abstract / Description: 

Advances in information technology have provided many benefits for people with disabilities, including wide availability of textual content via text to speech, flexible control of motor wheelchairs, captioned video, and much more. People with cognitive disabilities benefit from easier communication, and better tools for scheduling and reminders. Will advances in machine learning enhance this impact? Progress in natural language processing, autonomous vehicles, and emotion detection, all driven by machine learning, may deliver important benefits soon. Further out, can we look for systems that can help people with cognitive challenges understand our complex world more easily, work more effectively, stay safe, and interact more comfortably in social situations? What are the technical barriers to overcome in pursuing these goals, and what are the theoretical developments in machine learning that may overcome them?
