Bootstrap-Based Regularization for Low-Rank Matrix Estimation
We develop a flexible framework for low-rank matrix estimation that allows us to transform noise models into regularization schemes via a simple bootstrap algorithm. Effectively, our procedure seeks an autoencoding basis for the observed matrix that is stable with respect to the specified noise model; we call the resulting procedure a stable autoencoder. In the simplest case, with an isotropic noise model, our method is equivalent to a classical singular value shrinkage estimator. For non-isotropic noise models--e.g., Poisson noise-- the method does not reduce to singular value shrinkage, and instead yields new estimators that perform well in experiments. Moreover, by iterating our stable autoencoding scheme, we can automatically generate low-rank estimates without specifying the target rank as a tuning parameter.
The tiny robot that just wants to be your friend: Cozmo develops bond with its owner - and its eyes light up when it sees them
It looks like it could be the child of Pixar favourites Wall-E and Eve, but the tiny robot developed by Anki is real enough to hold in the palm of your hand. Cozmo is a tiny robot equipped with a powerful brain and an'emotion engine,' allowing it to create an evolving bond with its human companions. The 180 robot reacts to your emotions and remembers the faces it's seen before, communicating through complex facial expressions and its own unique language.

For data work, "It's actually pretty hard to argue *against* using Python"
I wrote my first Python program in 1996, and my most recent a couple of weeks ago, so I can appreciate Python's advance to cover a very broad range of computing tasks. I don't program much anymore, but in my work over the years -- and yours too, if you do much coding -- data manipulation has always played an important role. You can't build and apply analytical models, manage transactions, craft a Web experience, or carry out any other significant task without investing time and attention to data acquisition, cleansing, and structuring. Python is ideal for those tasks, and then for model building and data analysis. Python is great for natural language processing (NLP), in particular, a special interest of mine, and for just about any data work that interests you, chances are.
This tiny robot is a real life Wall-E
Just 2.5-inches tall with a fondness for meaningful eye contact and heavy lifting, Cozmo is a robot companion designed to seem like it has a soul. And like any faux-sentient creature, he gets grumpy when he's poked or turned on his back. You can tell by the way his eyes narrow and he grunts at you. Cozmo looks like a lot of toy robots on the market (and Pixar's Wall-E), but he's been programmed to move, interact, and emote like a complicated movie character. His creators at Anki designed him using a combination of artificial intelligence, image and voice recognition, and animation.
New robot AntiAgeist joins jury of Beauty.AI 2.0
June 27, Baltimore, MD - Youth Laboratories, the organizer of the first beauty contest judged by a panel of robots today announced the inclusion of AntiAgeist, an algorithm evaluating the difference between the chronological age of contest participants and the age predicted by a system of deep neural networks trained to predict human age. "We are very happy to have AntiAgeist on our jury of robot judges, since this is a rather novel idea of looking at beauty through the prism of how successfully the person is aging. We encourage teams from all over the world to submit algorithms and ideas on how machines can evaluate human beauty to the Beauty.AI contest. Best algorithms will get monetary prizes and will be promoted worldwide", said Anastasia Georgievskaya, general manager of Beauty.AI. Insilico Medicine specializes in drug discovery and biomarker development for a broad range of diseases with a mission to accelerate and improve lead generation and pre-clinical studies within biotechnology and pharmaceutical industries.
The AI 'Top Gun' that can beat the military's best
It is every Top Gun's worst nightmare - an AI can can outmanoeuvre them in the air. Now researchers have tested their AI on a retired top gun - and left him stunned. Retired United States Air Force Colonel Gene Lee took on the AI in a simulator - and lost. An AI has beated Air Force pilots in simulated showdowns for the first time. Retired United States Air Force Colonel Gene Lee took on the AI in a simulator.
Philip Guo - Python Tutor: The First Three Years
For the past six years, I've been developing Python Tutor (pythontutor.com), Thousands of people use it every day to run tens of thousands of pieces of code in seven languages: Python, Java, JavaScript, TypeScript, Ruby, C, and C . This tool has also become a platform for HCI, educational technology, and computing education research. Most recently, it formed the basis for my faculty job applications that got me a job at UC San Diego. How did this project grow from nothing to its current state? I've been wanting to write a "history of Python Tutor" article for a while now but never found a good time to do so.
Beyond video games: New artificial intelligence beats tactical experts in combat simulation
Artificial intelligence (AI) developed by a University of Cincinnati doctoral graduate was recently assessed by subject-matter expert and retired United States Air Force Colonel Gene Lee - who holds extensive aerial combat experience as an instructor and Air Battle Manager with considerable fighter aircraft expertise - in a high-fidelity air combat simulator. The artificial intelligence, dubbed ALPHA, was the victor in that simulated scenario, and according to Lee, is "the most aggressive, responsive, dynamic and credible AI I've seen to date." Details on ALPHA - a significant breakthrough in the application of what's called genetic-fuzzy systems are published in the most-recent issue of the Journal of Defense Management, as this application is specifically designed for use with Unmanned Combat Aerial Vehicles (UCAVs) in simulated air-combat missions for research purposes. The tools used to create ALPHA as well as the ALPHA project have been developed by Psibernetix, Inc., recently founded by UC College of Engineering and Applied Science 2015 doctoral graduate Nick Ernest, now president and CEO of the firm; as well as David Carroll, programming lead, Psibernetix, Inc.; with supporting technologies and research from Gene Lee; Kelly Cohen, UC aerospace professor; Tim Arnett, UC aerospace doctoral student; and Air Force Research Laboratory sponsors. ALPHA is currently viewed as a research tool for manned and unmanned teaming in a simulation environment.

Robotic shopping trolley becomes a reality after 13-year-old boy drew one to help his grandmother
Engineers have developed a robotic shopping trolley for elderly customers based on a drawing by a boy who simply wanted to help his grandmother. Aidan McCann, 13, dreamed up a push cart with height adjustment features to help his grandmother Lydia who'isn't very strong'. He witnessed how the 4ft 11in 76-year-old finds it difficult to carry groceries from the shops and perform other physically demanding tasks due to her height. Bosses at engineering giant Doosan Babcock were so impressed with Aidan's design they selected it as their overall winner at the Scottish Engineering Special Leaders Award 2015 Users can make the trolley go up and down by the flick of a switch. The idea is to lift bags of shopping towards the users so that they don't have to bend down and lift it up themselves.
