DIMACS Workshop on Distributed Optimization, Information Processing, and Learning

My colleague Waheed Bajwa, Alejandro Ribeiro, and Alekh Agarwal are organizing a Workshop on Distributed Optimization, Information Processing, and Learning from August 21 to August 23, 2017 at Rutgers DIMACS. The purpose of this workshop is to bring together researchers from the fields of machine learning, signal processing, and optimization for cross-pollination of ideas related to the problems of distributed optimization, information processing, and learning. All in all, we are expecting to have 20 to 26 invited talks from leading researchers working in these areas as well as around 20 contributed posters in the workshop.

Registration is open from now until August 14 — hope to see some of you there!

Register soon for the 2017 North American School of Information Theory

The site for the 2017 North American School of Information Theory is now live and registration will begin next week. The IT Schools have been going strong for the last few years and are a great resource for students, especially new students, to get some exposure to information theory research beyond their own work and what they learned in class. Most schools do not have several people working on information theory. For students at such institutions the school provides a great way to meet other new researchers in the field.

Why I will no longer do research sponsored by the Department of Homeland Security

Shortly after the inauguration, the new administration announced a blanket ban on  refugees and any entry into the US from 7 proscribed countries. The announcement was met with outrage, ridicule, and legal opposition. Despite its obvious unconstitutionality and complete lack of guidance on implementation, the Department of Homeland Security (DHS) engaged in a weekend of harassment and intimidation at our border. They were big cheerleaders of the effort but also incompetent and unprofessional. At the same time, a pilot project I had worked on, funded by DHS, was about to be submitted for a “phase 2” extension. In light of those events, I asked to be taken off the project entirely and will no longer seek funding from DHS.

Now the administration has revealed an harsh and chilling new plan to terrorize immigrants and their families through a campaign of demonization and deportation. The biggest cheerleader of this plan is the new DHS secretary, John F. Kelly. This only validates my decision: I cannot conduct research under the aegis of an agency whose planned actions run counter to nearly everything I believe. It would be unethical for me to continue to do so. If that were not enough, DHS has also ceded its technical authority on security/privacy issues. I have little confidence that real security/privacy is a priority.

Supporting graduate students in engineering often requires getting funds from multiple sources; it is difficult to sustain a research group (and in some places, get tenure) on NSF (or NIH, in my field at least) funding alone. The usual suspects are industry, foundations, the various defense research programs (ARO, ONR, AFOSR, DARPA), or other government departments (DOE comes to mind). If you work in security/privacy, DHS has also been a (relatively) new source of research funding. Many of the other government agencies do fund basic research but some are focused more on applied research or transitioning research to practice.

There are many considerations to balance. As a theory and algorithms person, the overhead of making “deliverables” can take time away from basic research. Some programs have a lot of check-ins and progress updates which don’t necessarily work with the academic calendar. Finally, trying to describe your theory question about graph topology and its impact on convergence rates of some estimator as crucial to improving “warfighter capabilities” can sometimes feel awkward. My approach thus far has been to try things out. If the proposal is on research I would want to do anyway and everything is public domain and open, then OK. If the experience is not so good/fun, maybe I will consider alternatives. Basic research has lots of applications; improving a control algorithm could yield better drone targeting or more accurate laser-aided surgery.

It was with this in mind that I proceeded with a DHS-funded project on privacy-sensitive anomaly detection. It was a short project but raised a number of interesting new problems and models that I would like to explore, if possible, in the future. It also funded a student whose studies are now threatened by this very administration. Indeed, the entire academic research enterprise in the US is under threat. As academics we can sign petitions, but it is not enough. Scott Aaronson wrote very eloquently about this issue after the initial ban was announced (see also Terry Tao). My department has seen a dramatic decrease in the number of applicants in general and not just from Iran. We were just informed that we can no longer make TA offers for students who are unlikely to get a visa to come here.

The Department of Homeland Security has demonstrated its blatant disregard for moral norms. Why should we trust its scientific norms? What confidence do we have that funding will not be used in some coercive way? What does it say to our students when we ask them to work for DHS? Yes, the government is big, but at some point the argument that it’s mostly the guy at the top who is bad but the rest of the agency is still committed to good science becomes just too hard to swallow. I decided that I can’t square that circle. Each one of us should think hard about whether we want to.

Put José M.F. Moura on the IEEE President Ballot!

José Moura was nominated to be considered as a candidate for IEEE President. The IEEE Board of Directors (BoD) is the body that decides who the candidates will be. They were also behind the proposed IEEE constitutional amendment that was opposed by more than 25 IEEE Societies because it was a rather naked power grab that would have moved much of the constitution to bylaws that could be amended by a small group of individuals, reducing regional representation, and reducing technical activities representation. You can think of it as an attempt by the BoD to Make IEEE Great Again. Prof. Moura spoke up against the amendment (including at an ITSOC BoG meeting) and in the end the amendment did not pass.

It is likely that the BoD’s decision to not nominate him is retaliation for his actions in defense of what he (and many others) felt are the best interests of the IEEE. While this Trump-esque approach to handling dissent may be popular in Washington, it seems quite inappropriate for an international organization such as IEEE. There is a petition at the IEEE website to put him on the ballot. It needs around 4,000 signatures and students members are also welcome to sign. You sign in with your IEEE account and then go to “Annual Election Petitions.” Note this is not a vote for him, but rather allowing him to be on the ballot. Please consider signing!

CFP: T-SIPN Special Issue on Distributed Signal Processing for Security and Privacy in Networked Cyber-Physical Systems

Special Issue on Distributed Signal Processing for Security and Privacy in Networked Cyber-Physical Systems

GUEST EDITORS:

SCOPE
The focus of this special issue is on distributed information acquisition, estimation, and adaptive learning for security and privacy in the context of networked cyber-physical systems (CPSs) which are engineering systems with integrated computational and communication capabilities that interact with humans through cyber space. The CPSs have recently emerged in several practical applications of engineering importance including aerospace, industrial/manufacturing process control, multimedia networks, transportation systems, power grids, and medical systems. The CPSs typically consist of both wireless and wired sensor/agent networks with different capacity/reliability levels where the emphasis is on real-time operations, and performing distributed, secure, and optimal sensing/processing is the key concern. To satisfy these requirements of the CPSs, it is of paramount importance to design innovative “Signal Processing” tools to provide unprecedented performance and resource utilization efficiency.

A significant challenge for implementation of signal processing solutions in CPSs is the difficulty of acquiring data from geographically distributed observation nodes and storing/processing the aggregated data at the fusion center (FC). As such, there has been a recent surge of interest in development of distributed and collaborative signal processing technologies where adaptation, estimation, and/or control are performed locally and communication is limited to local neighborhoods. Distributed signal processing over networked CPSs, however, raise significant privacy and security concerns as local observations are being shared by neighboring nodes in a collaborative and iterative fashion. On one hand, applications of CPSs are severely safety critical where potential cyber and physical attacks by adversaries on signal processing modules could lead to a variety of severe consequences including customer information leakage, destruction of infrastructures, and endangering human lives. On the other hand, the need for cooperation be- tween neighboring nodes makes it imperative to prevent the disclosure of sensitive local information during distributed information fusion step. At the same time, efficient usage of available resources (communication, computation, bandwidth, and energy) is a pre-requisite for productive operation of the CPSs. To accommodate these critical aspects of CPSs, it is of great practical importance and theoretical significance to develop advanced “Secure and Privacy Preserving Distributed Signal Processing” solutions.

The spirit and wide scope of distributed signal processing in revolutionized CPSs calls for novel and innovative techniques beyond conventional approaches to provide precise guarantees on security and privacy of CPSs. The objective of this special issue is to further advance recent developments of distributed signal processing to practical aspects of CPSs for real-time processing and monitoring of the underlying system in a secure and privacy preserving manner while avoiding degradation of the processing performance and preserving the valuable resources. To provide a systematic base for future advancements of CPSs, this special issue aims to provide a research venue to investigate distributed signal processing techniques with adaptation, cooperation, and learning capabilities which are secure against cyber-attacks and protected against privacy leaks. The emphasis of this special issue is on distributed/network aspects of security and privacy in CPSs. Papers with primary emphasis on forensics and security will be redirected to IEEE Transactions on Information Forensics and Security (TIFS). Topics of interest include, but are not limited to:

  • Security and Privacy of distributed signal processing in networked CPSs.
  • Distributed and secure detection, estimation, and information fusion.
  • Security and privacy of consensus and diffusive strategies in networked systems.
  • Secure and privacy preserving distributed adaptation and learning.
  • Security and privacy of distributed sensor resource management in networked systems.
  • Distributed event-based estimation/control in networked CPSs.
  • Detection and identification of potential attacks on distributed signal processing mechanisms.
  • Application domains including but not limited to, smart grids, camera networks, multimedia network, and vehicular networks.
