Google Gboard now lets you draw to search emoji because why not

  Google Gboard now lets you draw to search emoji because why not Google’s excellent Gboard for Android is getting a few updates today meant to speed up your conversations a little bit. Most notably, you can now draw emoji. No, this doesn’t mean you get to turn your scribbles into your own emoji, but Google will recognize what you’re trying to draw and offer up some suggestions. The feature likely builds off of the technology in Google’s AutoDraw app introduced a couple of months ago, which similarly turns your doodles into clean clip art.

If you paid any attention to Google 's big developer conference earlier this year then you'll know artificial intelligence is about to get big - really big. It ' s already powering most of Google 's apps, one way or another, and the other giants in tech are scrambling to keep up. So what's all the fuss about?

If you paid any attention to Google's big developer conference earlier this year then you'll know artificial intelligence is about to get big - really big. It's already powering most of Google's apps, one way or another, and the other giants in tech are scrambling to keep up.

So what's all the fuss about? Here we're going to dig deeper into some of the AI announcements Google shared at I/O 2017, and explain how they're going to change the way you interact with your gadgets - from your smartphone to your music speakers.

The basics of AI

In broad terms artificial intelligence (usually) refers to a piece of software or a machine that simulates smart, human-like intelligence - even if it's just a hollow robot being operated by a person behind a curtain, pretending to respond to your commands, that's still a kind of AI.

Google Drive will automatically back up your hard drive later this month

  Google Drive will automatically back up your hard drive later this month While Google Drive is already a decent cloud storage tool, it’s about to get a lot more useful: starting June 28, the service will let you back up entire folders from your hard drive, and keep them in sync with your account. You’ll need to first download the Backup and Sync tool for your PC or Mac when it launches; once you’ve signed in, you’ll be able to choose which folders on your desktop you want to keep backed up, and access them through Drive across your devices. That sounds handy for people who already use Drive extensively – it’d certainly be nice to have a powerful search function for backed up files.

IBM beefs up its powerful cognitive computers with Google 's AI tools. Google wants to add AI to Raspberry Pi gadgets. “We think these new capabilities will help power a next generation of on-device speech processing, visual search, augmented reality, and more.”

Within that you've got all kinds of branches, categories and approaches. As you may have noticed, different types of AI are better at different tasks: the AI responsible for beating humans at board games isn't necessarily going to be any good at holding up a conversation across an instant messenger app, for instance.

The type of AI Google is most interested in is known as machine learning, where computers learn for themselves based on huge banks of sample data. That could be learning what a picture of a dog looks like or learning how to drive a car, but whatever the end goal, there are two steps: training and inference.

During training, the system is fed with as much sample information as possible - so maybe millions of photos of dogs. The smart algorithms inside the AI then try and spot patterns in the images that suggest a dog, knowledge that's then applied in the inference stage. The end result is an app that recognises your pets in pictures.

Google reveals when it'll stop supporting Pixel and Nexus phones

  Google reveals when it'll stop supporting Pixel and Nexus phones Wondering when you should upgrade your Nexus or Pixel? Based on the info Google listed on its support page, it's staying true to its word. The Pixel and the Pixel XL, which were released in 2016, will get the latest Android updates until October 2018. They'll get security updates until October 2019, the same month Google will stop providing customer service for them.

AI in Google's apps and engines

Artificial intelligence is already all over Google's apps, whether it's in spotting which email messages are likely to be spam in Gmail, or making recommendations about what you'd like to listen to next in Google Play Music. Any decision not made by a human could be construed as AI of some kind.

Another example is voice commands in the Google Assistant. When you ask it to do something, the sound waves created by your voice are compared to the knowledge Google's systems have gained from analysing huge numbers of other audio snippets, and the app then (hopefully) understands what you're saying.

Translating text from one language into another, working out which ads best match which sets of search results, all of these jobs that apps and computers do can be enhanced by AI. It's even popped up in the Smart Reply feature recently added to Gmail - short snippets of text you might want to use in response, based on an (anonymous) analysis of countless other emails.

Google can turn an ordinary PC into a deep learning machine

  Google can turn an ordinary PC into a deep learning machine Time is one of the biggest obstacles to the adoption of deep learning. It can take days to train one of these systems even if you have massive computing power at your disposal -- on more modest hardware, it can take weeks. It's also very flexible: there's a standard, modular interface that lets you use virtually any training model, data set or parameters. You don't need to replace everything just to change one component. And since it's open source, you could easily see the community share its own models to help you get started.

Considering the hype around AI nowadays, which has even reached TV show like Silicon Valley (see Not Hotdog app), it would be interesting to see if Apple addresses its future plans for AI at WWDC 2017, which will start next month.

And Google isn't slowing down, either. The company is busy working hard to improve its efforts in AI, as we saw at I/O earlier in the year - that means more efficient algorithms, a better end experience for users, and even AI that can teach itself to be better.

Google's latest AI push

We've talked about machine learning but there's a branch of machine learning that Google engineers are specifically interested in called deep learning - that's where AI systems try and mimic the human brain to deal with vast amounts of information.

It's a machine learning technique made possible by the massive amounts of computational power now available to us. In the case of the dog pictures example we mentioned above, it means more layers of analysis, more subtasks making up the main task, and the system itself taking on more of the burden of working out the right answer (so figuring out what makes a dog picture a dog picture, rather than being told by programmers, in our earlier example).

Deep learning means machine learning that relies less on code and instructions written by humans, and deep learning systems are known as neural networks, named after the neurons in the human brain. On stage at Google I/O 2017 we saw a new system called AutoML, which is essentially AI teaching itself - whereas in the past small teams of scientists have had to choose the best coding route to produce the most effective neural nets, now computers can start to do it for themselves.

Google launches its AI-powered jobs search engine

  Google launches its AI-powered jobs search engine Looking for a new job is getting easier. Google today launched a new jobs search feature right on its search result pages that lets you search for jobs across virtually all of the major online job boards.The idea here is to give job seekers an easy way to see which jobs are available without having to go to multiple sites only to find duplicate postings and lots of irrelevant jobs.

On its servers, Google has an army of processing units called Cloud TPUs (Tensor Processing Units) designed to handle all this deep thinking. In fact, Google makes some of its AI available to all via the TensorFlow portal - developers can plug the smart algorithms and machine learning power into their own apps, if they know how to harness it. In return, Google gets the best AI minds and apps in the business using its own services.

Google's AI future

There was no doubt during the I/O 2017 keynote that Google thinks AI will be the most important area of technology for the foreseeable future - more important, even, than how many megapixels it's going to pack into the camera of the Pixel 2 smartphone.

You can therefore expect to hear a lot more about Google and artificial intelligence in the future, from smart, automatic features in Gmail to map directions that know where you're going before you do. The good news is that it seems keen to bring everyone else along for the ride too, making its platforms and services available for others to make use of, and improving the level of AI across the board.

One of the biggest advances you'll see on your phone is the quality of the digital assistant apps, which are set to take on a more important role in the future: choosing the apps you see, the info you need, and much more. We've also been treated to a glimpse of an app called Google Lens, a smart camera add-on that means your phone will know what it's looking at and be able to make decisions at all times.

The AI systems being developed by Google go way beyond our own consumer gadgets and services too - they're being used in the medical profession as well, where deep learning systems can spot the spread of certain diseases much earlier than doctors can, because they've got so much more data to refer to.

Google tightens measures to remove extremist content on YouTube .
Alphabet Inc's Google will implement more measures to identify and remove terrorist or violent extremist content on its video sharing platform YouTube, the company said in a blog post on Sunday. Google said it would take a tougher position on videos containing supremacist or inflammatory religious content by issuing a warning and not monetizing or recommending them for user endorsements, even if they do not clearly violate its policies.
