Remember that senstence: "We generated more data than there are stars in the Universe"well, this is what that information looks like.      After a week with a heavy heart, I truly enjoyed this one even though it might have been staged. Thank you Jimmy Fallon and Nicole Kidman for the light hearted comedy.   Join the CompressiveSensing subreddit or the Google+ Community and post there !

I first heard about Extreme Learning Machines from a presentation at the Paris Machine Learning Meetup #6 Season 1 on Botnet detection by Joseph Ghafari (a resource for this approach can be found here). These constructions are essentially nonlinear functions of random linear projections. Today, we have a paper that aims at showing how one/few iterations of these functions can provide similar results as deep neural networks. Fast, simple and accurate handwritten digit classification using […]

I can safely say that most French people are extremely sad because, over the years, these cartoonists have been indiscriminate in taking down the powerful of all kinds. Here is another aspect of this which has not translated well in the foreign press coverage. Some figures, like Cabu, "raised" us during our childhood by being the friendly cartoonist-patient adult figure we would look up to every Wednesday afternoons on a kid TV show. For U.S. folks, think a Mr. Rogers like figure, […]

Waheed just mentioned the following to me: Distributed computating of Dictionary Learning.Cloud K-SVD: A Collaborative Dictionary Learning Algorithm for Big, Distributed Data by Haroon Raja, Waheed U. Bajwa This paper studies the problem of data-adaptive representations for big, distributed data. It is assumed that a number of geographically-distributed, interconnected sites have massive local data and they are interested in collaboratively learning a low-dimensional geometric structure […]

As a blogger, do you want to write more like William Faulkner, or more like Ernest Hemingway? "[W]hat blogging taught me is to be more immediate and more direct in what I want to write. Maybe it's the difference between Faulkner and Hemingway, I don't know. 'The paper was white, the text was black.' But, I'm more reminded what Kurt Vonnegut said, that he wrote books for people who are very busy and didn't have a lot of time to... Read more

The headset combines VR and augmented reality to create an interesting, new experience.

The technique resembles that used to create children's pop-up books, except instead of using paper, the researchers used materials such as silicon.

I have written before that offensive humor is the edge on the blade of liberty. Giving offense has a long and critical tradition. Without the right to offend, we do not have the right to breathe. Because someone, somewhere, right now, is offended by our breath. Offending Muslims with caricatures of Muhammed isn’t nice. Nor is […]

Recently, Vikas Sindhwani talked about Random Embeddings, Matrix-valued Kernels and Deep Learning. As a follow-up, I mentioned this Book on The Discrepancy Method by Bernard Chazelle (thanks to Sebastien) that should allow us to make more appropriate choices in the Random Features space when approximating Kernel Machines.Here is the actual paper on arxiv that Vikas mentioned in his talk (It had been mentioned here earlier as well): Quasi-Monte Carlo Feature Maps for Shift-Invariant Kernels by […]

Having featured the work of Ehsan before, it is just a question of time before we get to have a peak at an implementation of this. I can't wait.Approximate Subspace-Sparse Recovery in the Presence of Corruptions via $\ell_1$-Minimization by Ehsan Elhamifar, Mahdi Soltanolkotabi, Shankar SastryHigh-dimensional data often lie in low-dimensional subspaces corresponding to different classes they belong to. Finding sparse representations of data points in a dictionary built from the collection of […]

Following the development of commercial secondary lithium-ion batteries (LIBs), this article illustrates the progress of therein-utilised anode materials from the first successful commercialisation to recent research activities. First, early scientific achievements and industrial developments in the field of LIBs, which enabled the remarkable evolution within the last 20 years of this class of batteries, are reviewed. Afterwards, the characteristics of state-of-the-art commercially available […]

This butterfly has not been photoshopped. It is exactly half male and half female, a very rare condition known as gynandromorphy. This results in the dramatically different coloring on each half of the animal in species such as this one, in which the sexes have noticeably different looks. The gynandromorph butterfly was found by chance … Continue reading →

@gappy3000 @geomblog @igorcarron "Why pre-training helps" would have been a fine title.— snippyhollow (@syhw) January 7, 2015 h/T to Giuseppe Guissepe, Gabriel and Suresh for the discussion.Here is a new insight from a paper that is up for review at ICLR2015:We give an informal description. Suppose G is a group that acts on a set X by moving its points around ( e.g., groups of 2 x 2 invertible matrices acting over the euclidean plane). Consider x2X, and let Ox be the set of all points […]

Physical Review E 90, 052501 (2014) Murray and colleagues have reported a new technique for creating patterned surface-alignment of liquid crystals: using the tip of an atomic force microscope to inscribe grooves in a polymer layer [1]. The method allows a largely arbitrary, and ultra-high resolution, alignment of the liquid crystal to be imposed at the surface, which, in turn, may be used to induce on-demand a wide range of interesting topological defect patterns. [1] B. S. Murray, R. A. […]

Soft Matter 10, 9105 (2014) Chen and colleagues have reported what is essentially a new liquid crystal phase, which they name the random grain boundary phase [1]. The mesophase is observed in achiral molecules with a ‘hockey-stick’ shape and may be considered as a type of dark conglomerate phase. Like previous dark conglomerates observed in bent-core systems, its basis is smectic layering and it spontaneously forms chiral domains of opposite handedness that display optical activity. […]

When I wrote about A Quick Panorama of Sensing from Direct Imaging to Machine Learning, I was merely showing a parallel between two approaches. But a year later, we are now seeing another aspect of The Great Convergence: Two ways to go about a similar task (blind deconvolution), the compressive sensing approach determining sample complexity (how many images must be taken for the task) and eventually the transfer function with different arguments using concentration of measures results and the […]
