This NSF report from the Office of the Inspector General has some really horrendous examples of data fabrication, plagiarism, and other misconduct by PIs and graduate fellowship (GRFP) recipients. It’s true that bad behavior taints the whole program: how good is the GRFP selection process if students like this get awards?
This article on Bhagat Singh Thind is fascinating. We need a modern Ghadar Party here. But this is so bizarre: “[o]ut of necessity and ingenuity, Thind, along with several dozen South Asians during the interwar decades reinvented themselves as itinerant spiritual teachers and metaphysical lecturers who would travel from city to city, giving lectures and holding private classes.”
A photo gallery by Lotfi Zadeh: some of these are really beautiful portraits. Also the variety! I remember not really understanding portraiture when I was younger but I think I “get it” a bit more now. Or at least why it’s interesting. There’s even a photo of Claude Shannon… from the email:
Prof. Lotfi Zadeh, who passed away in 2017, was an avid photographer who grew up in a multicultural environment, surrounded himself with a cosmopolitan crowd, and always kept his mind open to new ideas. In the 1960s and 70s, he enjoyed capturing the people around him in a series of black and white portraits. His burgeoning career gave him access to a number of artists, academics, and dignitaries who, along with his colleagues, friends, and family, proved a great source of inspiration for him.
THE SQUIRCLE IS SO FASCINATING!
I helped organize a workshop at IPAM on privacy and genomics. Videos (raw) are up now.
Kamalika and I gave a tutorial at NIPS last week on differential privacy and machine learning. We’ve posted the slides and references (updates still being made). It was a bit stressful to get everything put together in time, especially given how this semester went, but it was a good experience and now we have something to build on. It’s amazing how much research activity there has been in the last few years.
One thing that I struggled with a bit was the difference between a class lecture, a tutorial, and a survey. Tutorials sit between lectures and surveys: the goal is to be clear and cover the basics with simple examples, but also lay out something about what is going on in the field and where important future directions lie. It’s impossible to be comprehensive; we had to pick and choose different topics and papers to cover, and ended up barely mentioning large bodies of work. At the same time, it didn’t really make sense to put up a slide saying “here are references for all the things we’re not going to talk about.” If the intended audience is a person who has heard of differential privacy but hasn’t really studied it, or someone who has read this recent series of articles, then a list without much context is not much help. It seems impossible to even make a real survey now, unless you make the scope more narrow.
As for NIPS itself… I have to say that the rapid increase in size (8000 participants this year) made the conference feel a lot different. I had a hard time hearing/understanding for the short time I was there. Thankfully the talks were streamed/recorded so I can go back to catch what I missed.
I keep posting ads for postdocs with other people but this is actually to work with little old me!
Department of Electrical and Computer Engineering
Rutgers, The State University of New Jersey
The Department of Electrical and Computer Engineering (ECE) at Rutgers University is seeking a dynamic and motivated Postdoctoral Fellow to work on developing distributed machine learning algorithms that work on complex neuroimaging data. This work is in collaboration with the Mind Research Network in Albuquerque, New Mexico under NIH Grant 1R01DA040487-01A1.
Candidates with a Ph.D. in Electrical Engineering, Computer Science, Statistics or related areas with experience in one of
- distributed signal processing or optimization
- image processing with applications in biomedical imaging
- machine learning theory (but with a desire to interface with practice)
- privacy-preserving algorithms (preferably differential privacy)
are welcome to apply. Strong and self-motivated candidates should also have
- a strong mathematical background: this project is about translating theory to practice, so a solid understanding of mathematical formalizations is crucial;
- good communication skills: this is an interdisciplinary project with many collaborators
The Fellow will receive valuable experience in translational research as well as career mentoring, opportunities to collaborate with others outside the project within the ECE Department, DIMACS, and other institutions.
The initial appointment is for 1 year but can be renewed subject to approval. Salary and compensation is at the standard NIH scale for postdocs.
To apply, please email the following to Prof. Anand D. Sarwate (firstname.lastname@example.org):
- Curriculum Vitae
- Contact information for 3 references
- A brief statement (less than a page!) addressing the qualifications above and why the position is appealing.
- Standard forms: Equal Employment Opportunity Data Form [PDF] Voluntary Self-Identification of Disability Form [PDF] Invitation to Covered Veterans to Self-Identify [PDF].
Applications are open until the position is filled. Start date is flexible but sometime in Fall 2016 is preferable.

And now, a little pre-ITA self-promotion. As I wrote earlier, LabTV interviewed me and a subset of the students in the lab last semester (it was opt-in). This opportunity came out of my small part in the a large-scale collaboration organized by Mind Research Network (PI: Vince Calhoun) on trying to implement distributed and differentially private algorithms in a system to enable collaborative neuroscience research. Our lab profiles are now up! They interviewed me, graduate students Hafiz Imtiaz, Sijie Xiong, and Liyang Xie, and an undergraduate student, Kevin Sun. In watching I found that I learned a few new things about my students…
It’s been a busy January — I finished up a family vacation, moved into a new apartment, helped run the MIT Mystery Hunt, started teaching at Rutgers, and had two conference deadlines back to back. One of my goals for the year is to blog a bit more regularly — I owe some follow-up to my discussion of the MAP perturbation work, which I will be talking about at ITA.
In the meantime, however, one of the big tasks in January is graduate admissions. I helped out with admissions at Berkeley for 4 years, so I’m familiar with reviewing the (mostly international) transcripts, but the level of detail in transcript reporting varies widely. The same is true for letters of recommendation. I’m sure this is culturally mediated, but some recommenders write 1-2 sentences, and some write paeans. This makes calibrating across institutions very difficult. While the tails of the distribution are easy to assess, decisions about the middle are a bit tougher.
Rutgers, like many engineering school across the country, has a large Masters program. Such programs serve as a gateway for foreign engineers to enter the US workforce — it’s much easier to get hired if you’re already here. It’s also makes money for the university, since most students pay their own way. In that regards, Rutgers is a pretty good deal, being a state school. However, it also means making admissions decisions about the middle of the distribution. What one wants is to estimate the probability an applicant will succeed in their Masters level classes.
It’s a challenging problem — without being able to get the same level of detail about the candidates, their schools, and how their recommenders feel about their chances, one is left with a kind of robust estimation problem with a woefully underspecified likelihood. I’ve heard some people (at other schools) discuss GPA cutoffs, but those aren’t calibrated either. More detail about a particular individual doesn’t really help. I think it’s a systemic problem with how graduate applications work in larger programs; our model now appears better suited to small departments with moderate cohort sizes.
I’m in the process of moving to New Jersey for my new gig at Rutgers. Before I start teaching I have to go help run the the Mystery Hunt, so I am a little frazzled and unable to write “real” blog posts. Maybe later. In the meantime, here are some links.

Of late we seem to be learning quite a bit about early hominins and hominids (I had no idea that hominini was a thing, nor that chimps are in the panini tribe, nor that “tribe” is between subfamily and genus). For example,
they have sequenced some old bones in Spain. Extracting sequenceable mitochondrial DNA is pretty tough — I am sure there are some interesting statistical questions in terms of detection and contamination. We’ve also learned that some neanderthals were pretty inbred.

I’m happy to announce that in January 2014 I will be joining the Electrical and Computer Engineering Department at Rutgers, The State University of New Jersey, as an Assistant Professor.
