Six of the best 4k HDR TVs

The Guardian

Your current TV is showing its age. Its resolution is resolutely HD (so very 00s) and it doesn't even respond to voice commands, no matter how loud you bawl. Maybe the time has come to upgrade to something cutting edge. Connected smart TVs are now standard fare. With integrated streaming services, you can season binge from Netflix and Amazon Prime Video without the need for an additional set top box or dongle – or multiple remotes.

Why Not Appoint an Algorithm to Your Corporate Board?


Though Elon Musk has famously warned humanity about the dangers of artificial intelligence, his shareholders might be well-served by having an algorithm on Tesla's board of directors. In recent years, Tesla has become a cautionary tale for how difficult it is for part-time directors to oversee charismatic, strong-willed CEOs--especially ones who are the founding visionaries of their companies. Given how Elon Musk has landed the company in hot water with the Securities and Exchange Commission with his erratic tweets and mocking disregard for the regulatory regime dictating the proper behavior of a publicly traded company, it's little wonder that Tesla's board has been accused of being "asleep at the wheel." Perhaps their seeming unwillingness to rein him in is due to the Tesla directors' personal loyalty to Musk. Or maybe they simply don't want to spend the time to "preapprove" Musk's tweets about the company, especially with the less conventional hours and fast pace the CEO keeps.

Safety-Obsessed Volvo Goes After Distracted, Speedy Drivers


Volvo has had it up to här with drivers. The Swedish carmaker has spent decades building a reputation based on safety (and low-key luxury), but humanity's taste for speeding, distraction, and impaired driving remains a threat no airbag, semi-autonomous system or moose-detection system can neutralize. So this week, Volvo announced a raft of potentially controversial initiatives that will help deliver on its Vision 2020 goal--no more deaths or serious injuries in its new cars--by making its customers behave. After announcing a few weeks ago that it will limit the top speed of all its new cars to 112 mph, Volvo will roll out efforts to eliminate impaired driving, keep young drivers in check, and help its competitors benefit from its years of safety research. Improving driver behavior hinges on knowing how the driver is behaving, so Volvo--at an event also marking 60 years since it introduced the three-point safety belt--will start putting inward-facing cameras in all its cars.

The Mysterious Math of How Cells Determine Their Own Fate


In 1891, when the German biologist Hans Driesch split two-cell sea urchin embryos in half, he found that each of the separated cells then gave rise to its own complete, albeit smaller, larva. Somehow, the halves "knew" to change their entire developmental program: At that stage, the blueprint for what they would become had apparently not yet been drawn out, at least not in ink. Original story reprinted with permission from Quanta Magazine, an editorially independent publication of the Simons Foundation whose mission is to enhance public understanding of science by covering research developments and trends in mathematics and the physical and life sciences. Since then, scientists have been trying to understand what goes into making this blueprint, and how instructive it is. It's now known that some form of positional information makes genes variously switch on and off throughout the embryo, giving cells distinct identities based on their location.

Tesla Sues Zoox and More Car News This Week


Thinking about the fantastic pie-in-the-sky future is always a fun exercise. I, too, want a self-driving car. But some weeks, it's clear everyone needs to come down to earth. This was one of them. Tesla sued two other electric vehicle companies focusing on self-driving for trade secret theft, proving that building this tech will be a grind.

The latest 'Star Wars Battlefront II' mode mixes human and AI players


DICE and EA are determined to keep Star Wars Battlefront II fresh a year after the loot box fiasco effectively came to an end. They're releasing an update on March 26th that introduces Capital Supremacy, a Clone Wars-era mode that includes AI characters for the first time in competitive Battlefront II matches. Two teams of 20 human players, each augmented by 12 computer-guided troopers, will race to invade each other's spaceships. It's a complex, multi-stage mode that could lead to prolonged fights if there are any big upsets. It starts out with a territory control phase on the ground.

Tesla's Autopilot may make room for cars entering your lane


Tesla's Autopilot system can ease some of the burden of driving, but it's not always polite (just ask anyone who's been cut off). Now, however, it appears to be learning some added manners. After a couple of weeks of off-hand reports, drivers now believe that Autopilot cedes the right of way when it detects that a car up ahead wants to switch into your lane. If a vehicle is making its intentions clear, Autopilot appears to make that car stand out on your instrument cluster and slow down to create a space. It's not certain what Tesla's technology is looking for (most likely the signal lights), but it seems to work just like what you'd expect from a courteous driver.

Data Science or Machine Learning? Here's How to Spot the Difference


In this new world of artificial intelligence and data management, it's easy to get confused by some of the terms that are most commonly used in the IT world. For example, data science and machine learning have a lot to do with each other. It's not surprising that many people with only a passing knowledge of these disciplines would have trouble figuring out how they differ from one another. Join nearly 200,000 subscribers who receive actionable tech insights from Techopedia. First of all, data science is really a broad, overarching category of technology that encompasses many different types of projects and creations.

How to Manually Scale Image Pixel Data for Deep Learning


Images are comprised of matrices of pixel values. Black and white images are single matrix of pixels, whereas color images have a separate array of pixel values for each color channel, such as red, green, and blue. Pixel values are often unsigned integers in the range between 0 and 255. Although these pixel values can be presented directly to neural network models in their raw format, this can result in challenges during modeling, such as in the slower than expected training of the model. Instead, there can be great benefit in preparing the image pixel values prior to modeling, such as simply scaling pixel values to the range 0-1 to centering and even standardizing the values.

Commentary: The Asset Management Industry Should Take the Lead on A.I. Standards


The increased sophistication of fintech poses many policy concerns, especially when harnessing A.I. in asset management. Currently, there is a lack of international regulatory standards for A.I. and machine learning in asset management. Since A.I. is already being used by investment managers to improve operational structure, investment strategy, and trading efficiency, the need to address this policy gap is urgent. On March 25, the Institute of Electrical and Electronics Engineers (IEEE), the world's largest professional organization devoted to engineering, is launching Ethically Aligned Design (EAD1e), a set of guidelines for the design and use of intelligent systems. The initiative is a step in the right direction because it begins to provide the ethical foundations for designing transparent and impartial systems--but more must be done.
