APPLE'S LATEST IPHONES ARE PACKED WITH AI -SMART


The three new iPhones unveiled next to Apple’s glassy circular headquarters Wednesday look much like last year’s iPhone X. Inside, the devices’ computational guts got an invisible but more significant upgrade.
Apple’s phones come with new chip technology with a focus on helping the devices understand the world around them using artificial intelligence algorithms. The company says the improvements allow the new devices to offer slicker camera effects and augmented reality experiences.
For the first time, non-Apple developers will be allowed to run their own algorithms on Apple’s AI-specific hardware. That could enliven the iTunes app store with rich new experiences for socializing, creating art, or getting things done. Machine learning algorithms can help apps to understand and respond to what’s happening in photos and video, for example. Combined with Apple’s support for augmented reality, more AI oomph could help your iPhone transform the world around you.
All three iPhones announced Wednesday include a new chip called the A12, designed in-house by Apple. It has a unit called a neural engine, dedicated to running the neural network software behind recent advances in the ability of machines to understand speech and images.
Apple introduced the iPhone’s first neural engine last year inside the iPhone X, 8, and 8 Plus. It was the first major smartphone with a dedicated chip core for neural networks.
The neural engine helped power the iPhone X’s Face ID facial-recognition unlock system and Animoji feature that transposes a person’s facial expressions onto cartoon animals. But the powerful new hardware wasn’t plugged into the Core ML feature Apple provides for developers who want to bake AI smarts into their own apps.
On Wednesday Apple announced that the neural engine is now significantly more powerful. Last year’s debut model could crank through 600 billion operations per second. The new version can work almost 10 times faster, reaching 5 trillion operations per second. Some of that speedup may come from using smaller transistors inside the A12, with features as small as 7 nanometers. Last year’s iPhone chip had 10-nanometer transistors. The A12 is a generation ahead of other smartphone chips, although mobile chip maker Qualcomm has said its own 7-nanometer technology will ship this year.
Apple says the new neural engine helps the new phones take better pictures. When a user presses the shutter button, the neural engine runs code that tries to quickly figure out the kind of scene being photographed, and to distinguish a person from the background. That information feeds into the iPhone camera’s portrait mode. On the more expensive XS models, portrait mode includes an impressive new function that makes it possible to change the depth of field on a photo after it has been taken, blurring or sharpening the background.
App developers can play with the power of Apple’s new neural engine through Core ML, a framework the company offers to help programmers deploy machine learning on Apple devices. The company says that this allows developers to run machine learning code nine times faster than on the iPhone X, while using a tenth of the energy.
Sports-centric app developer Nex Team, based in San Jose, got early access to some new Apple devices for testing. The company’s CEO David Lee says being able to tap the new version of the neural engine has made his basketball app HomeCourt much better.

What's With All the Squares? QR Codes A QR code is comprised of an array of squares, some of which are used for the image sensor to position itself (that's the large squares on three of the corners), while the rest of the cells contain version and format information as well as the data itself, of course, along with error correction coding. Whereas most of the barcodes you come across are one-dimensional, such as UPC labels on items at the store, QR codes are two-dimensional and offer many advantages. For instance, QR codes can be scanned in any direction instead of only one, they can contain thousands of alphanumeric characters versus only a dozen or so, and when configured with a high level of error correction they are particularly capable at continuing to function after sustaining damage. The more error correction a QR code has, the less data it can store and incidentally, the more data that is stored within a QR code, the more squares it will have. More squares are a

Google is killing off its Gmail substitute app before it could become popular Inbox came with provisions for snoozing emails to later, trying latest artificial intelligence (AI)-powered experiences like Smart Reply, Nudges, high-priority notifications Google is set to shut down its alternate mailing app Inbox in March 2019, giving users time to shift to the traditional Gmail by then, the company has said in a blog post. Launched in 2014, Inbox was introduced as an innovative new email app that lived alongside Gmail and served as an experimental platform for Google to try newer mailing features that could be incorporated in Gmail later. However, it could not gather enough user base and updates to justify its existence. “We want to take a more focussed approach to help us bring the best email experience to everyone. As a result, we’re planning to focus solely on Gmail and say goodbye to ‘Inbox’ at the end of March 2019,” Matthew Izatt, Product Manager at Gm

Telecom firms are back to square one  The Supreme Court order disallowing telecom operators from using Aadhaar for verification will prolong the time taken to get mobile phone connections and could increase customer acquisition costs by as much as 10 times.  “With enrolment via Aadhaar, we took 30 minutes to get a customer on board and now one will have to wait for 5-6 days for our officers to go to their addresses and verify their details. It seems like we have gone back in time and now enrolment will happen slowly, like th e earlier times,” said a senior executive of a private telco.   The apex court’s verdict curbing the use of the unique identity number will also add financial pressure on the industry, which is reeling under debt of more than Rs 7 lakh crore amid competition that is eroding revenue and profitability.  The cost of enrolling a new customer with Aadhaar is about Rs 30, according to another senior telecom company executive. Now, with verification going back to ol
