"Colorization APIs are becoming widespread; AI-colorized historical photos are circulated without caveat. But is AI colorization providing an accurate image of the past? To find out, I digitally desaturated these color photos by Sergey Prokudin-Gorsky, taken between 1909 and 1915. I then colorized the photos using the DeepAI Image Colorization API." "Here's the AI's attempt to color these photos." "And here are the original color photos." twitter.com/gwenckatz/status/1

"NVIDIA's new Grace CPU will power the world's most powerful AI-capable supercomputer." "The Swiss National Computing Center's (CSCS) new system will use Grace, a revolutionary Arm-based data center CPU introduced by NVIDIA today." blogs.nvidia.com/blog/2021/04/

"Why AI reduces productivity in radiology -- yet" "It is a well-known paradox that technology adoption, not only related to AI, is leading to a J-curve shaped change in productivity." The idea is that introducing a new technology initially decreases productivity. Productivity increases later as people learn to change workflows to make productive use of the new technology, and ultimately ends up higher than the status quo before the introduction of the technology. chrisonmedtech.com/why-ai-redu

"Analysis of 100 weeks of curated AI news" from Skynet Today. Articles related to "robots" grew much faster than other areas. After late 2019, articles regarding facial recognition grew much faster than others, with Covid-19 articles making a sudden entrance starting early 2020. Google dominates the AI news cycle in terms of mentions of institution names. skynettoday.com/digests/ai-new

"NVIDIA's new Grace CPU will power the world's most powerful AI-capable supercomputer." "Taking advantage of the tight coupling between NVIDIA CPUs and GPUs, Alps is expected to be able to train GPT-3, the world's largest natural language processing model, in only two days -- 7x faster than NVIDIA's 2.8-AI exaflops Selene supercomputer, currently recognized as the world's leading supercomputer for AI by MLPerf." blogs.nvidia.com/blog/2021/04/

"15 graphs you need to see to understand AI in 2021". "We're Living in an AI Summer": between 2000 and 2019, AI papers went from being 0.8% of all peer-reviewed papers to 3.8%. "China Takes Top Citation Honors": In 2017, China took the lead on most peer-reviewed papers on AI, now they are top in citations. "Faster Training = Better AI": In 2018, it took 6.2 minutes to train the best system on ImageNet; in 2020 it took 47 seconds. spectrum.ieee.org/tech-talk/ar

Theoretical model for neural activity of mouse brain. "The work is based on a physics concept known as critical phenomena, used to explain phase transitions in physical systems, such as water changing from liquid to a gas. In liquid form, water molecules are strongly correlated to one another. In a solid, they are locked into a predictable pattern of identical crystals. In a gas phase, however, every molecule is moving about on its own." esciencecommons.blogspot.com/2

"It has long been known that obesity is an inflammatory disease, i.e. a chronic defensive reaction of the body to stress caused by excess nutrients. Based on this knowledge, a group of researchers ... decided to try to fight obesity by preventing inflammation -- and they succeeded. Their paper ... shows that digoxin, a drug already in use against heart diseases, reduces inflammation and leads to a 40% weight loss in obese mice, without any side effects." cnio.es/en/news/publications/d

Aging signatures across diverse tissue cells revealed... in mice. So this organization, the Tabula Muris Consortium, was created to make a giant dataset of mouse aging data, and that data set is called the TMS FACS. TMS stands for Tabula Muris Senis, and FACS stands for fluorescence-activated cell sorting. elifesciences.org/for-the-pres

Spintronics at room temperature. Spintronics is when, instead of storing information using the presence or absence of electrons, information is stored using the spin of electrons. Researchers "have now constructed a semiconductor component in which information can be efficiently exchanged between electron spin and light -- at room temperature and above." liu.se/en/news-item/genombrott

"Histones are tiny proteins that bind to DNA and hold information that can help turn on or off individual genes. Researchers have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells simultanously." news.ki.se/technique-allows-ma

Riddle me this: what is it about finding cows in satellite images that makes it "funny, in a 'Far Side' kind of way"? news.ucsb.edu/2021/020241/spot

The first opposed thumb showed up 160 million years ago, but it was probably unrelated to our lineage as it's a dinosaur. But it's being called "Monkeydactyl" anyway. It is a pterosaur to be precise, which is a winged dinosaur, in fact the first dinosaur to have evolved powered flight. birmingham.ac.uk/news/latest/2

"Special light waves that can penetrate even opaque materials as if the material was not even there." "There is a class of very special light waves for which this does not apply: for any specific disordered medium -- such as the sugar cube you may just have put in your coffee -- tailor-made light beams can be constructed that are practically not changed by this medium, but only attenuated." tuwien.at/en/tu-wien/news/news

"A review of formal methods applied to machine learning." Safety-critical systems use formal methods as an integral part of the software development process. By "formal methods", they mean strong, mathematically-grounded guarantees that the software will behave reliably. As an example they cite the avionics industry. A shift took place in the 2010 with the adoption of the DO-178C standard. It introduced safety certification by formal methods. arxiv.org/abs/2104.02466

The "attention" system works by having an "attention" function that takes three vectors, one called the "query", one called the "key", and one called the "values", and outputs a vector. Inside this "attention" function are a bunch of additional learnable parameters. It works because conceptually, the "attention" lets you "query" using any of these keys to find values that are "similar". theaisummer.com/transformer/

"Scientists create online games to show risks of AI emotion recognition." "A team of researchers have created a website -- emojify.info -- where the public can try out emotion recognition systems through their own computer cameras. One game focuses on pulling faces to trick the technology, while another explores how such systems can struggle to read facial expressions in context." theguardian.com/technology/202

"Time to regulate AI that interprets human emotions." "There is deep scientific disagreement about whether AI can detect emotions. A 2019 review found no reliable evidence for it." Scholars have called for mandatory, rigorous auditing of all AI technologies used in hiring, along with public disclosure of the findings." nature.com/articles/d41586-021

"Taiwan Semiconductor Manufacturing Co. plans to spend $100 billion over the next three years to expand its chip fabrication capacity, a staggering financial commitment to address booming demand for new technologies." "Now at the center of a global chip supply crunch, Taiwan's biggest company has pledged to work with customers across industries to overcome a deluge of demand." TSMC is the world's biggest chip company but most people have never heard of them. bloomberg.com/news/articles/20
