4:41 PM | Stop telling boys to go into STEM
Stereotyping is always a bad thing, and most people don’t realize that men suffer just as badly from stereotypes as women. Let’s look at science: there has been a ton of work going into how to attract girls and women into scientific endeavors, particularly those that are very math-intensive.  Much of the discussion centers on […]

1:27 PM | A Frightening Episode.
A couple of days ago, I passed out at my desk. Now, I have a lot of experience passing out from alcohol. This was not like that. I felt hot and tingly. It came on very suddenly. I felt very disoriented, and then I lost consciousness. I awoke a moment or two later, drenched in […]

6:01 AM | Piketty Reviews: the year in review
Fraternity! Liberty! Equality! Pick only one.Thomas Piketty's book "Capital in the Twenty-first Century" became quite the phenomenon this year. Originally published in French, it was translated into English in 2014 and has since elicited a large amount of feedback. I have collected a series of book reviews over the course of this year that provide a bit of perspective on the book. This could either prove to be prophetic, or another "End of History and the Last Man". The diversity of responses […]

6:00 AM | Video and Slides: Random Embeddings, Matrix-valued Kernels and Deep Learning
From the Simons Institute Workshop on Spectral Algorithms: From Theory to Practice, here is:   Random Embeddings, Matrix-valued Kernels and Deep Learning by Vikas SindhwaniThe recent dramatic success of Deep Neural Networks (DNNs) in many applications highlights the statistical benefits of marrying near-nonparametric models with large datasets, using efficient optimization algorithms running in distributed computing environments. In the 1990's, Kernel methods became the toolset of […]

10:50 PM | Haskell's biggest flaw
And then a great, deep voice, like as that of James Earl Jones, spake unto me, saying, The greatest flaw of Haskell is the inability to define the identity function in a point-free style.

8:53 PM | Learning with Fredholm Kernels - implementation -
Here is a way to do semi-surpevised learning with kernels (and even with Random Features at the very end) Learning with Fredholm Kernels by Qichao Que Mikhail Belkin and Yusu Wang. In this paper we propose a framework for supervised and semi-supervised learning based on reformulating the learning problem as a regularized Fredholm integral equation. Our approach fits naturally into the kernel framework and can be interpreted as constructing new data-dependent kernels, which we call […]

6:45 PM | Blogging for Science Outreach, Blogging for Myself
A few weeks ago, I blogged about a new paper that came out in Public Understanding of Science on science bloggers’ practices, motivations and target audiences. In the paper, Mathieu Ranger and Karen Bultitude interviewed seven authors of popular science blogs. Among their findings, most of the bloggers they interviewed cited personal motivations to blog about science: “The most commonly reported motivation was intrinsic in nature, […]

4:45 PM | What’s Eating You, and/or Vice Versa: Microbes
If you enjoyed the new opera “What’s Eating You“, which was about two people and all the microbes in and on them, you will (probably) enjoy this newly published study. It’s about people, their microbes, and who eats whom: “The microbes we eat: abundance and taxonomy of microbes consumed in a day’s worth of meals […]

3:04 PM | Informed choices through Machine Learning-2: Pitting together Kumble, Kapil, Chandra
Continuing my earlier ‘innings’, of test driving my knowledge in Machine Learning acquired via Coursera,  I now turn my attention towards the bowling performances of our Indian bowling heroes. In this post I give a slightly different ‘spin’ to the bowling analysis and hope I can ‘swing’ your opinion based on my assessment. I guess that […]

2:16 PM | Drexel Snapshot x2: Conserving Central African Wildlife Diversity
Central Africa’s Congo Basin is a biodiversity hotspot, meaning it’s a region with an incredibly rich array of plants and animals, many of which are found nowhere else—and which face threats to survival that include deforestation, climate change and hunting. A Drexel professor and her students are part of an international effort to protect this … Continue reading →

1:51 PM | Winningly cute animals of science
Nature magazine assembled this video of the alleged Year’s Ten Cutest Animals in Science. Number 9 was awarded the 2014 Ig Nobel Prize for biology: When you watch and listen to the video, pay special attention to the narrator’s very first sentence. It’s a not-so-subtle, friendly dig at Nature‘s rival journal, Science. (Thanks to Connie Villalba for […]

1:05 PM | Bird-feather counters exhibited pluck, tediously
Many humans have spent days, months or years counting feathers. Here are exciting highlights from some of their reports. In 1936 Alexander Wetmore, of the US National Museum in Washington, gathered all the published reports he could find about someone or other counting how many feathers were on particular birds. “The work of feather counting […]

6:00 AM | More Oil and Compressive Sensing Connections
Felix Herrmann followed through to yesterday's "Another Donoho-Tao Moment ?" which itself was a followup to Sunday Morning Insight: The Stuff of Discovery and Hamming's time: Scientific Discovery Enabled by Compressive Sensing and related fields. Here what he has to say:Hi Igor,I agree with your assessment that the application of CS to seismic data acquisition may not qualify as a major scientific discovery but it will almost certainly lead to major scientific breakthroughs in crustal and […]

6:06 PM | How to fail as a skeptic
A few months ago, I wrote about my experience attending an atheist meeting.  If you don’t want to read it, I basically spent most of the time dealing with an argumentative jerk.  On the other hand, I expected that going in. Part of the reason I expected that is because there is a large amount […]

3:30 PM | Another Donoho-Tao Moment ?
We always hear about the need to justify mathematics as regards to applied work. Remember this "Donoho-Tao moment"? (from this 2008 newletter)[Mark Green's] favorite moment of the program came when the NSF panel – which was simultaneously conducting its first site visit – asked: Is this interdisciplinary work? Participant David Donoho (statistics, Stanford), another major contributor to the genesis of compressed sensing, reportedly […]
