8:00 PM | In Brief: GoPro Announces Hero4 Line of Action Cameras
Another year, another GoPro release (how many people actually upgrade every year?) This generation of the ubiquitous action cams builds on last year's strengths--more high-speed fps recording options and better 4K video. On the high end, the $500 GoPro Hero4 Black now shoots 4K video at 30fps (double that of the Hero3 Black), as well as 120fps at 1080p (and other resolution/framerate options). The $400 Hero Silver has the same recording capabilities of last year's Black edition, but now […]

6:40 PM | Wouldn’t trade places
Last week at the Heidelberg Laureate Forum, I was surrounded by the most successful researchers in math and computer science. The laureates had all won the Fields Medal, Abel Prize, Nevanlinna Prize, or Turing Award. Some had even won two of these awards. I thought about my short academic career [1]. If I had been […]

6:00 PM | In Brief: FAA Begins Granting Production Companies Drone Waivers
Last Thursday, the FAA announced that it has begun granting video production companies exemptions to its unmanned aircraft systems (UAS) regulations. Six companies now have permission to use quadcopters and drones for production purposes, after convincing the FAA that their operations would meet a minimum standard for safety. Operators at these companies, for example, would hold private pilot certificates, keep the aerial systems within line of sight at all times, and keep flights restricted to […]

6:04 AM | Image Classification with A Deep Network Model based on Compressive Sensing
Using compressive sensing to build the first layers of a neural network, we are getting there. Image Classification with A Deep Network Model based on Compressive Sensing by Yufei Gan, Tong Zhuo, Chu HeTo simplify the parameter of the deep learning network, a cascaded compressive sensing model "CSNet" is implemented for image classification. Firstly, we use cascaded compressive sensing network to learn feature from the data. Secondly, CSNet generates the feature by binary hashing […]

3:02 PM | Votation sur l’assurance maladie: plus on paie, plus on soutient la caisse publique
Les résultats de la votation fédérale sur la “caisse publique” témoignent d’une réalité concrète et financière : alors que l’initiative visant à instaurer une caisse maladie publique a été nettement rejetée par 61.9% des votants, celle-ci a reçu un accueil beaucoup plus positif dans les cantons assujettis aux primes mensuelles les plus élevées. Les résultats en […]

2:50 PM | When good chat bots go bad
Allow me to start off by expunging any possible notion that what you will read in the following post has anything to do with Sky Net-like types of robotic systems. There will likely come a day when I will write further on the topic of artificial intelligence. Today however, it seems that the subject at hand is more aptly described as artificial ineptness.Last week I started writing code for an open-source chat-bot program. My goal was to create something that was basically an open-source […]

3:00 AM | Microsoft Closes SVC
Some additional thoughts Microsoft Research source Omer Reingold is a brilliant researcher, and now all can see that he is also a very classy and thoughtful person. As you all know by now, he and many others have suddenly lost their jobs with the closing of Microsoft’s Silicon Valley Campus (SVC) Research Lab. The lab […]

3:47 PM | On shellshock
The 'net is currently focused on Shellshock, leading to interesting discussions of the responsibility for the problem. Recently, someone posted Not a bash bug, which was linked on Hacker News. The argument there is that: I would argue that the bash security concern is not a bug. It is clearly a feature. Admittedly, a misguided and misimplemented feature, but still a feature.... It is an old precept for security on unix systems, that environment variables shall be controlled by the parent […]

1:26 PM | Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals (and a comment)
This is exciting but I have included my thoughts below: Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals by Ardeshir Mohammad Ebtehaj, Efi Foufoula-Georgiou, Gilad Lerman, Rafael Luis Bras We demonstrate that the global fields of temperature, humidity and geopotential heights admit a nearly sparse representation in the wavelet domain, offering a viable path forward to explore new paradigms of sparsity-promoting assimilation and compressive retrieval of spaceborne earth […]

7:52 PM | The great reformulation of algebraic geometry
“Tate helped shape the great reformulation of arithmetic and geometry which has taken place since the 1950′s.” — Andrew Wiles At the Heidelberg Laureate Forum I has a chance to interview John Tate. In his remarks below, Tate briefly comments on his early work on number theory and cohomology. Most of the post consists of […]
