3:30 PM | Videos and Slides: Next-Generation Sequencing Technologies - Elaine Mardis (2014)
Last time I mentioned Elaine Mardis videos giving a summary of next generation sequencing the video shot up and garnered more than 127,893 viewers. Coincidence ? I think not :-)Here is the new survey on Next Generation Sequencing where she talks about the current PacBio and Nanopore technology add-ons to the lab. I note the biology people liking the term "massively parallel" sequencing. Anyway, those third generation technologies are very interesting because instead of cutting DNA strands in […]

3:20 PM | Long Live the Fall Workshop (guest post by Don Sheehy)
An announcement for the Fall Workshop in Computational Geometry, by Don Sheehy.  In all the conversation about SoCG leaving the ACM, there were many discussions about ownership, paywalls, and money.  This leads naturally to questions of ideals.  What can and ought a research community be like?  What should it cost to realize this?  Isn't it enough to bring together researchers and in an unused lecture hall at some university somewhere, provide coffee (and wifi), […]

9:09 AM | On Detecting Messaging Abuse in Short Text Messages using Linguistic and Behavioral patterns
The use of short text messages in social media and instant messaging has become a popular communication channel during the last years. This rising popularity has caused an increment in messaging threats such as spam, phishing or malware as well as other threats. The processing of these short text message threats could pose additional challenges such as the presence of lexical variants, SMS-like contractions or advanced obfuscations which can degrade the performance of traditional filtering […]

5:00 AM | A compressed sensing perspective of hippocampal function
This is a theory but the main question really is: how do we go using fMRI and similar technology to figure out if this is really what is going on ? Food for thought.A compressed sensing perspective of hippocampal function by Panagiotis C. Petrantonakis and Panayiota PoiraziHippocampus is one of the most important information processing units in the brain. Input from the cortex passes through convergent axon pathways to the downstream hippocampal subregions and, after being appropriately […]

9:25 PM | Adam Tour Diaries #7: A Whirlwind Weekend
I got this shot heading into our first TV station. (Or was it radio? It’s all a blur.)We had a busy weekend prepping and performing our first three shows in Oz.We are in the lovely and awesomely foodie town of Melbourne, where the crowds are incredible. I’ve been furiously adding and modifying and refining bits of the show (an endless process, I’m afraid), and if there’s one thing I’ve learned about myself, it’s that when I’m putting a ton of creative […]

5:00 PM | In Brief: Witness the Kilobot Swarm
Earlier this month, we wrote about how roboticists use swarms of ants as models for programming collective groups of robots, but past experiments in swarming bots (or drones) have only utilized dozens of machines. In a new demonstration of the open-source kilobots project, Harvard roboticist Mike Rubenstein shows off how a system of over a thousand tiny robots could organize themselves to elegantly form two-dimensional shapes. The kilobots--which unfortunately sound like "killerbots"--are to be […]

4:13 PM | IPAM workshop on Computational Photography and Intelligent Cameras, February 4 - 6, 2015
Yohann Tendero let me know of this IPAM workshop entitled Computational Photography and Intelligent Cameras that is set to take place in LA on February 4 - 6, 2015. I wonder if we are going to see some Data Drive Sensor Design/ Zero Knowledge Sensor Design. Anyway, you can also apply for financial assitance to attend the workshop.

3:21 PM | Back to Work
Harvard classes start up in a few weeks, and officially, my sabbatical is over.  I'm back in my office, trying to get back into a Harvard routine.I notice that I've been very light in posting over my sabbatical.  After my term as chair, I was enjoying being in the background, hidden away a bit.  I'm not sure if I'll get back into blogging -- it seems already to be a technology of the past -- but I figure I'll start again and see what happens.So some short notes.  On my to-do […]

9:25 AM | Fastfood: Approximate Kernel Expansions in Loglinear Time - The Paper -
Compressive sensing is not the only place where multiplying a vector or a matrix with a Gaussian matrix is a big deal for large scale problem (see the recent Random Matrices Are Too Damn Large ! and Another Comment on " Random Matrices Are Too Damn Large !"). If you recall this is also a problem for Random Kitchen Sinks, a randomized version of AdaBoost (a connection with compressive sensing is mentioned here). There, the training set in Machine Learning is used as a dictionary in order to […]

6:30 PM | Time exchange rate
At some point in the past, computer time was more valuable than human time. The balance changed long ago. While everyone agrees that human time is more costly than computer time, it’s hard to appreciate just how much more costly. You can rent time on a virtual machine for around $0.05 per CPU-hour. You could […]

5:22 PM | L’adaptation à l’altitude
Cette année, les Goulus ont visité les Andes en passant trois semaines à plus de 3000 m d’altitude, en y montant avec le mythique « train de Tintin » qui passe par un col situé à 4800 m, la hauteur du Mont-Blanc. Là nous avons pu constater que nous avions la chance de ne pas être trop atteints par le mal aigu des montagnes, juste un peu essoufflés et somnolents. Par contre bon nombre de passagers ne se sentaient pas bien […]

12:58 PM | Sunday Morning Insight: Self-Configuring Universal Linear Optical Components
Figure from [1]I discovered David Miller's work on Dan Piponi's recent G+ feed, here is how Dan summarized it:I really like this paper: http://www-ee.stanford.edu/~dabm/430.pdf Imagine you have an incoming laser beam. It will have some kind of spatial profile, for example it might be a gaussian beam that's brighter in a hump in the middle and falls off towards the edges. Or it might have two "humps". Now imagine you want to perform an arbitrary linear […]

8:52 AM | Don’t let the pressure affect you
One question that sometimes comes up regarding DFT computation (typically at zero pressure) is whether one can safely neglect the effect of pressure at ambient conditions. Here’s a simple back-of-the-envelope calculation that shows why it’s OK to neglect pressure under normal circumstances. The effect of pressure on absolute energy Under constant temperature and pressure conditions, the […]

12:51 AM | Subhash Khot’s prizewinning research
I already congratulated Subhash Khot in my last post for winning the Nevanlinna Award, but this really deserves a separate post.  Khot won theoretical computer science’s highest award largely for introducing and exploring the Unique Games Conjecture (UGC), which says (in one sentence) that a large number of the approximation problems that no one has been able to prove […]

7:55 PM | Adam Tour Diaries #6: Whoops and Whew
Thursday and Friday are all press days. Jamie and I did some TV, we did a crap-ton of radio, and then we did more of both. Taken around by the awesome Lucy and G, we found that everyone we dealt with was amazingly nice. I know I'm supposed to say that, but it's frigging true!People we run into continue to be very enthusiastic about MythBusters, and they have run from ages 7 to 70 (well, he looked 70). It's also great to be hearing so many versions of the Aussie accent. I'm getting a […]
