to commit 4% of their annual gdp output to military spending — double the current target. he made the remarks during the western military alliance‘s summit in brussels. of nato's 29 members, just five met the current target this year. the first images have emerged from the hospital where 12 thai boys and their football coach are being treated after their remarkable rescue from a flooded cave. meanwhile, reports say the boys and the coach were sedated to stop them panicking as they made their escape. croatia have reached the world cup final for the first time ever after beating england. a strike from mario mandzukic in extra time gave croatia a 2—1victory. the win sparked euphoric celebrations across croatia as fans filled streets and squares waving flags and chanting. now on bbc news: click. > this week, tech watches wimbledon, restores voices, floats above london and makes a lovely stir—fry.
the thing i love about mit in boston is that whenever you open a door in a basement you could run into anything. unless it runs into you first. which might be why, for the seventh straight year, mit has been named the world's number one university. and, i am going to say it, this is one of my favourite places in the world. what i love about mit is that it is all over the place. the buildings have this brilliant higgledy—piggledy nature and inside is the same.
here at csail, for example, there is stuff all over the place. it is wonderful. the computer science and artificial intelligence lab, csail, is mit's ai powerhouse with some of the world's foremost researchers in the field. here, ai has taught itself to see through walls while robots are being built to swim through our bodies. why? well, i'll tell you later. but it is obvious that we are still only starting to explore how to use artificial intelligence and robotics. 20 years ago computation was a task reserved for experts because computers were large and expensive and you really needed to know what to do with them. but today, everyone has access to computation, and in fact computation is so prevalent. we don't even see how we depend on it. we don't notice how we depend on it.
the next 20 years will be about bringing ai and other technologies into our lives to help us with cognitive and physical work. it certainly seems that artificial intelligence is creeping into every aspect of technology these days. one of those is speech synthesis, which is that we have seen recently on click. it does raise interesting ethical issues, but the technology can certainly be used for good. paul carter has been to new york state to find out how new developments in speech synthesis are helping disabled people find their voice again. if you are on social media during the summer of 2014 chances are you were familiar with the ice bucket challenge. for many of us, al voice is an essential part of who we are. to lose it would be to lose a sense
of our very identity. here in yonkers in new york, one man who lost his voice to motor neurone disease has been given back his sense of self through technology. project revoice is an international initiative to help give people with mnd or als their voice back. using software from canada—based company lyrebird, it can synthesise an accurate recreation of someone‘s voice from a relatively small amount of audio. lyrebird's software was famously and controversially used last year to recreate the voices of us presidents donald trump and barack obama. voice of donald trump: i am not a robot. my intonation is different. pat quinn was one of the early co—founders of the challenge. he was diagnosed with als in march 2013. the extent of his illness now means he cannot speak.
he was one of the first to be given his voice back by project revoice. one of the things that we hear from people with als is that they, you know, that their voice really reflects themselves and their own thinking about themselves. but we also hear it from their family members and that is really where, you know, people say that we weren't thinking about the fact that we would not be able to hear this person speak any longer until it was gone. and now, suddenly, we missed their voice and missed that side of them. so there is something inherently unique about a person's voice that hopefully we are able to capture and keep in the future. pat concedes that his new voice is not perfect. because he did not record this voice prior to losing it, lyrebird used online videos and speeches as their basis. lyrebird's algorithms analyse several hours of quality recordings to digitally recreate a person's speech.
i don't think there are many companies before have done something that allow people to copy their voice off a small amount of audio. speech synthesis is an old research subject and it has been going on for more than 30 years. but what we provide is for people to really do it in their home and you can go to our website, record yourself for a few minutes, and after that you will get a voice. the hope is to extend the scope of project revoice more people internationally, to allow more people with mnd and als to recapture and recreate their own voice.
man's voice: this voice is terrible. i hate it. i sound like a professor i would not listen to. with project revoice we would like to see a person's voice be accessible as possible to them so that they can use their voice whenever they want to use it. and have it be ease—of—use, true ease—of—use. with voice banking and voice messaging generally we just want to try and bring it to as many people as we can and in as easy a way as possible and truly make it commonplace for people to be using their own authentic voices when they communicate. hello and welcome to the week in tech.
it was the week that a security researcher discovered that wearing juggalo style clown make—up could fool some facial recognition systems. juggalos are fans of hip—hop outfits the insane clown posse. thousands of fortnite players infected their computers with malware after downloading cheat software to try and improve their game. they say trailers give away the best bits of the film. somebody at sony pictures is in hot water after uploading the entire movie, khali the killer, to youtube instead ofjust the trailer. researchers at harvard have developed a robotic cockroach that can walk on land and water and even go for a dive. the ambulatory micro robot applies a voltage to the water in order to break the surface tension, allowing it to go for a swim. from walking on water to flying through the air with the greatest of ease. we have seen disney's stunt robot before but it has had an upgrade and now has a human—looking body.
the autonomous self—correcting aerial robot can make adjustments in the air to make sure it nails its death—defying leaps again and again. finally, the next time you are trapped on a desert island or want to make a romantic declaration in the sand, why not get a robot to do it? created by ivan miranda, this little robot makes strides in the sand, acting like a beach printer. maybe not the quickest way to get your sos message out though. bringing art to the masses through technology is something many have tried to achieve over the past few years. but here in london's hyde park there is something pretty big on display. so how can we see this recreated in a way that more people could see it? this is christo and jeanne—claude's the masta ba.
the name being a type of ancient egyptian tomb meaning ‘eternal house'. this one, though, is only temporary. made up of 7506 barrels and weighing 600 tons. if you are here, you can not exactly miss it. for those who are not in the vicinity, being able to enjoy this or wanting to see from all angles in the day or in the night—time light, well, you could do so with one of these. a google cardboard version provides a basic look around the installation. but a fuller experience as possible using the htc vive or steam. firstly, i've come indoors to do this because it does not matter where i am and i need a good wi—fi connection. so let's go. i can get up to five metres away, i believe. now it's time to start flying. 0k.
that is impressive, where you can see over the other side. it is quiet. no—one in the park today. it's dead. the night—time view is still a work in progress but i did get to see the subtle shadows and the colours that changed through the day. i am no stranger to a spot of vr but from an art perspective, i would like a second opinion. let's see if i can go over the top. it is wonderful to do this. that is a fantastic aerial view. problem is you start to get a bit tourist and look at london skyline. it is eerie that there seem to be no people in the park at all. ok, louisa, let me help you. what i think was fascinating for me is that you are an art expert yet you were more distracted by the london skyline, the park and the lack of people than actually being able to focus on the art. that is the trouble with this kind of thing. perhaps it'sjust for old dinosaurs like me but there is still something quite thrilling about being able to go up in the air. mastaba is a great piece but i would argue that
actually its impact is a physical impact, that when you walk in the serpentine, walk in hyde park and you come across this extraordinary mass, the scale of it, all that stuff, that does not come through on the vr. with a version 50 times the size planned for abu dhabi, you can see that scale is clearly important here. but whilst it may be a lot easier to create that in a virtual world, it is may be missing the point. that was lara. 0k. back to mit in boston now where i am walking around and around and around in order for an artificial intelligence to track me. that is me that you can see on that screen there. but what is really impressive here is the detector is not in this room at all. it is next door and it is seeing through this wall. it is called rf pose
and the transmitter uses low power radio signals that pass through walls but reflect off objects in the next room. everything reflects. notjust the human body. the ceiling, the walls, everything. to make sense of that mess and focus on the human body, you had to eliminate of them and that is a complex process and machine learning and deep learning is good at that. the system has taught itself to pull out the human skeleton from the mass of reflected signals and it can deal with many bodies in the room and, of course, it can see in the dark as well. the professor would like this to be used for healthcare as a way of checking on elderly patients without capturing any sensitive personal information or any actual images. in fact, the software is so sensitive it can even detect heartbeat. you could check for sleep apnoea, for example, that is disruption of breathing during sleep. you saw all the beats moment
by moment so you can look at the interval, the time between individual beats and look for arrhythmia. i have to say, on this trip to boston, i have noticed an interesting theme. an acceptance that artificial intelligence has its limits. the team behind the self—balancing cheetah robot want to fit it with human—controlled arms because ai is not up to the job of opening doors and manipulating objects — not yet, anyway. and a completely different piece of research is also eschewing ai altogether. this is an idea which hopes to block e—mails containing bullying, harassment and hate. so what is interesting is that here we are in the artificial intelligence department, but you are basically saying "ai is not cut out for this and we're gonna go back to humans again". yeah, i mean, we've — from talking to people who deal with harassment, we found that
harassment is really contextual, it's really personalised, often, to the person who's getting harassed, because often times, the person who is harassing them is sometimes using something that they know about that person to harass them. and so, we think that something like ai isn't going to be able to cover all the many ways that people are getting harassed and, in fact, people might be adversarially trying to get around the things that a model might be learning. they'll have sort of a very innocuous title for the email and maybe their harassment will be kind of hidden near the bottom and that way, you have to go and read it. it is an idea called squadbox and its aim is to use not a computer but your friends to spot and manage harassing emails. it's simple — your messages are intercepted and redirected to a squad of moderators youv‘e chosen and who will probably understand
what is personally offensive to you, even if it doesn't contain the obvious keywords. and what's really interesting here is that there are no swear words in here so there's "i think your work is fake and you are just out to make a profit off the backs of ha rd—working people. you should really re—evaluate your life" — i can see how an algorithm would pass that and say "that's fine". for now, squadbox has been geared to work with e—mail but its creators say that there's no reason why it couldn't be ported to work with social media and certainly, the moderation approach sounds, well, very social. csail is also at the forefront of robotics, building machines in shapes and sizes that challenge our very idea of what a robot is. primer, the so—called superhero robot, picks up different outfits or mini exoskeletons, depending on what it needs to do. off he goes! oh, it's like a really cool dying moth. for long journeys, it can roll up into a wheel. to cross water, it dons
a fold—up boat and set sail. and if needs be, it can abandon ship, too. the tiny transformer can even strap on a pair of wings and glide off into the future. so, this can be used for some medical applications. for example, we develop — last summer, we developed this kind of a stomach, like a simulator. so we also designed this capsule—sized origami robot, similar. we encapsulate it into ice, so it's like a capsule, so when we deploy it inside of the stomach... so it will melt in the stomach. yes, exactly, then we can use the electromagnetic field, orjust mri, to move this little robotic pill to move to some point where we want to deploy the drugs
or want to remove some, for example a battery or something, from your stomach. like a foreign object you have swallowed. yes. primer is controlled by manipulating a magnetic field and it uses a heating pad to help it fold. right now, you drive it using a makeshift controller. you can play. oh, can i play? yeah, just... oh, this is, like, really cute! so what might this be used for in the future then? we could use it for the space exploration. so we could launch out, send out, multiple — a stack of the different exoskeletons to mars, right? then use one small single robot to achieve different missions. elsewhere in the lab, here's an experiment in origami—inspired robotic muscles that can lift 1,000 times their own weight. it's going to break my scapula! last week you will remember this robot, which followed me around collecting my tennis balls as i prepared for wimbledon. well, sadly, i didn't quite make the draw, but it turns out, jen copestake did. yes, spen, it's a beautiful day
here at wimbledon where we're checking out all the technology behind the tennis tradition. artificial intelligence gets everywhere these days, even here at the all england club, where ibm's watson is busy at work behind the scenes. we're going to see three ways ai is being utilised at the tournament for content creators, players and fans. first, content creation. so where are we right now? so we're in the bowels of the broadcast centre and the rooms on the right hand side are what we affectionately refer to as ‘the bunkers‘. is there any chance of running into roger federer down here? there might be in the media restaurant, just around the corner. watson's incredible processing data power is being used to create highlight reels with no human involvement. it's listening to the noise of the crowd, looking for those — or listening for those really exciting moments. it's taking in the audio feed from the side of the court and, you know, those rallies you get where you get the real
"oohs" and "aahs" ? applause. what watson's doing is listening out for that. if the crowd's excited, then it marks that down as an exciting point. and then it's looking at the data points, so where are the pressure points in the match, and then it's also looking at how the players react. so how animated they are with their arms, how obviously emotive they are while they're doing that. and then it's combining all of those together to create an excitement level, and that gets fed into this dashboard and all of the points are ranked and then, at the end of the match, watson will also generate a highlights package based on all those exciting points and they give that to the content team so they can get it out really, really quickly. wow. players can also take advantage of this quick turnaround of highlights. instead of going through hours of video, each team is given a unique website to check. here's roger federer‘s unforced errors. this helps coaches create a narrative of what happened in the game and quickly see where they can improve, or better, their opponents. players are — we sort of sometimes
forget they are really the biggest fans of their own sport and they want to know how their friends are getting on, their rivals are getting on, but also that deeper statistics and insight that helps them in their own analysis of how they are playing is really valuable too. and for fans who want deep analysis, they can get it by accessing all of these stats via wimbledon‘s new facebook messenger bot, which is also driven by watson. and watson has one final data trick to show off. it's the first non—human to design a wimbledon poster. celebrating 150 years of the all england club, it used visual image recognition to scan over 300,000 historic photographs. the final result is this mosaic, made up of 8,400 individual images. instead of the usual colour matching, watson was taught to recognise the different elements of a photograph, such as umbrellas, and find umbrella photos to match. even the texture of the court is made up of other photos of courts. well played! that was jen at wimbledon. and back in boston, my robot tour has left me hungry for more even the texture of the court is made up of other photos of courts. well played!
that was jen at wimbledon. and back in boston, my robot tour has left me hungry for more and the spyce restaurant is where i'm going to feed my need. touchscreens take the orders, robots cook the meals, and the humans are relegated to the source stations. indian or chicken rice. . .. thai. an orange delivery box zips up and down a track transporting ingredients and dropping them into seven specially designed spinning pans. they toss the food, keeping a constant temperature via an induction plate
on the pan‘s side. the only thing letting down this computerised cohort of wok wielders is arguably the people in charge of delivery. they haven't called my name out yet. is that supposed to happen? ah, it was there all along. look at that! was i supposed to get a drink with my order? 0k. right, thanks. the concept is the brainchild of the spice boys — four mit grads who spotted a gap in this in this investor—filled tech town. early, early on, the very first prototype, you know, the very first idea of design was about 3.5 years ago. one of the key things that we, you know, made sure to pay attention to while designing this was, you know, it's a food robot, it has to handle food. and food is so — so unique, it comes in all different shapes, sizes and textures, so one of the key focuses was to, you know, design all of this equipment where it handled the food very gently, preserved the quality, and really preserved the integrity of the food while being able to, just, you know, use the wide variety of food that you see on our menu. now, this is obviously only suited
to stir—fries and maybe other dishes where everything is cooked together and presentation is not an issue. if you want a steak, dauphinoise potatoes and a drizzle of red winejus, well, you're gonna need a completely different robot. well, that's it from this robot restaurant, and that's the end of our us trip for this time. i hope you've enjoyed it. and you can see more of us on facebook and twitter throughout the week. thanks for watching. and would you like some kale with that? hello there. temperatures dipped a little bit at the start of this week. wednesday was a warm one, and those temperatures are going to continue to rise towards the end of the week. some places could be really quite hot during the course of the weekend. we also had a few showers around.
they will tend to fizzle out, but we could start thursday morning with one or two across some western areas, maybe north—west england, in towards wales. there could be quite a muggy start to some of the larger towns and cities across southern england and southern wales. now, we start thursday, then, on a rather cloudier note. clouds will tend to break up with some sunny spells developing, although the eastern coastal areas remaining a little bit cloudy through the day, and then showers will develop, and we think most of these will be across more western areas. now, some could be quite heavy, particularly across south—western scotland, maybe the western side of england to the west of the pennines, in towards wales and south—west england. and they will be very slow moving, almost stationary. some areas could get quite a lot of rainfall. the ground being so dry could lead to some local flooding, so watch out for that. but be warned, though — where you get the sunshine, especially in the south—east, 26 or 27 celsius. as we hurtle towards friday, looks like the risk of showers and thunderstorms begins to increase, and some of them could be on the heavy side.
friday starts off mainly dry, with the sunshine, although there will be showers from the word go across parts of north—west england and southern scotland. these will become more widespread across parts of wales, into the midlands, maybe southern england as well. like i mentioned, some of them could be quite intense, with the risk of some local flooding. temperature—wise, around 25, maybe 26 celsius, and some eastern coastal areas may hold onto that cool breeze. now, as we head on in towards the weekend, a big area of low pressure will be anchored to the north—west of the uk. this may bring further cloud, maybe outbreaks of rain, to scotland and northern ireland, but it's also going to draw much warmer air from the near continent. so from saturday it's definitely a north—west, south—east split, with outbreaks of rain across the north and west of scotland, maybe into the far north—west of england, as well. much of england and wales, though, dry and sunny. locally hot in places, maybe 28, 29 celsius in the south—east. on sunday it's a similar picture — breezier, with more cloud from northern ireland and western scotland. with outbreaks of rain, could see a few showers pushing into wales, north—west england. but elsewhere, across most of england and eastern wales,
a hot day to come. we could see one or two locations in the south—east reaching 30 or 3! celsius. so for the end of the week it looks like we will see an increase of showers and thunderstorms for a time, and then it starts to hot up as we head on into the weekend. welcome to bbc news — broadcasting to viewers in north america and around the globe. my name is ben bland. our top stories: showdown in brussels. president trump demands nato countries double their defence spending. the first pictures of the rescued
