Just watch out for the rodents. Oh, there a mouse data is all around us. We generate around 2. 5 billion gigabytes of it every day. Think of it as, well, theres no word for it really. Enormous. And were finding lots of new ways of gathering even more of it. Machines are now able to look at videos and interpret whats in the image, and with the number of cctv cameras around the town, imagine how much more data we can collect. But the Real Intelligence is not in capturing the data it in analysing it, and this is where Artificial Intelligence might make a real difference, making connections that we humans never would. Big data has accelerated our understanding of medical science in unimaginable ways. Its now influencing how hospitals treat patients, Police Forces manage crime and city officials run our towns. And its inevitable in the next 50 years that ai will play an even bigger role in our society and influence how we go about living. I recently met dj patil, former us president Barack Obamas chief data scientist, who is in charge of shaping how big data is being used by the government to make big policy decisions, whilst ensuring that al created by the Tech Companies treat everyone fairly and make good decisions. Thats where we have to start focusing more of our energy. Asking the question, how do we actually make sure that these algorithms are going to work the way we want . People are talking about Self Driving Cars. Is a Self Driving Car going to see someone with my skin tone or someone with a darker skin tone . A person with a wheelchair . Is that type of person in the data set . How do we start saying. So youre suggesting where a Self Driving Car would recognise you as something it should avoid . Avoid, yes. Because we have different skin colour. Are people with your skin colour the only ones in the data set . Am i ignored . Was that an accident . But what about, you know, someone with a handicap . What about a kid on a tricycle . Its not sufficient to say, oops, about the algorithm. We have to figure out a more robust process as these things are becoming more integrated in our society. And if weve learned anything from this weeks facebook story, its that Tech Companies are not the most transparent bunch. Facebook has been around for more than a decade and only now, by chance, have we got a glimpse of how its moderators decide what we see on its platform. So how do we make sure that the ai built by these same Tech Companies are using our data responsibly . So firstly it comes down to how are you trained. In our training these days, we often have found technologists are no longer trained in humanities. One of the most critical component of humanities is the notion of ethics. So what weve called for is that every data scientist, every economist, anybody who works with data, must have ethics integrated throughout their entire curriculum, so you construct and have the conversation and dialogue about what are the ethical implications of the choices you make. The second part of this is security of the data. How do you make sure that youre actually building the algorithms with security, the data sets with security, so somebody cant just break in . That has to no longer be an elective of outside. It has to be part of the core training. Once you have this component of that training, i think were going to have a new set of people who have the vocabulary to talk about it. But that doesnt take into account the speed at which data is happening and taking place today. So what do we do there . Number one, transparency. President obama signed an Executive Order that says by default all data the federal government, the us federal government, publishes must be open and machine readable, and what that allows people to do is be able to access the data, compare it, use it, and innovate with it. And that is the problem. How do we strike that balance . We need to know that an ai system is not biased, its learned from a data set that is representative of all of us and its decisions are fair, but we also dont want to stifle its progress, because when its used in the right way it really can change things for the better. What weve found in one of the problems around our local jail system is that theres a huge number of people just cycling in and out of the system. I mean the numbers are extraordinary more than 11 Million People through 3100 jails. They stay there an average 23 days. 95 never go to long term prison. It turns out theres a lot of Mental Health issues, a lot of drug addiction. So what happens to those people and where is the data going . It stays in silos. The Health Care System has a silo of it. And criminaljustice. So what happens if you just took and shared that information . If you said, hey, do you see sally in your data set . And they say, oh, yeah, we see sally all the time she has a drug problem. And if the Criminaljustice System was like, really . Well, why are we sending her to jail . Lets send her to the right intervention. She has a Mental Health issue. So, doing that, how much can you save . Whats the real impact . Miami dade, florida did this. It cost about 1. 5 million to train everybody in the right intervention and share the data and everything. The first year alone, they saved more than 10 million. But more importantly they were able to close a fulljail, and then later on they closed a second jail, because theyre getting people to the right care. Thank you very much for your time. Welcome to the week in tech. It was the week that volvo announced its working on an Ai Rubbish Truck that will follow collectors from house to house. Ikea said they will release smart light bulbs that can be controlled by voice and sync up with home devices like alexa and google assista nt. And google fancied another go at go success. The Ai System Alphago took on the worlds number one go player kejie, and won the series. Alphago learned to play by studying old matches and Playing Thousands of games against itself. The hope now is it will be used in medicine and science in the future. More bad news for uber this week, as it admitted it underpaid drivers in new york for more than two and a half years. Tens of thousands of drivers will now be paid about 900 each, which will mean uber paying out tens of millions of dollars. And only one month into the release of samsungs new Galaxy S8 Smartphone virus scanner, and its already been hacked. German hackers fooled the scanner with only a Paper Printer and a contact lens to make the fake eye. And is robocop from the 80s becoming a reality . Well, not quite, but dubai police want these robots to make up 25 of its force by 2030. They launched the unit on wednesday, which can forward video feeds to the police, settle fines, has facial recognition, and can speak nine languages. Id buy that for a dollar graffiti art has been one of the hottest Art Movements over the last few decades. Like many graffiti artists, graeme or xenz, the name he goes by cut his teeth on the streets. In this case, the streets of bristol. And he has since grown into the artist that we see on the roof of his east london studio. Today, hes taking a break to do this for us. But hes more known these days for these amazing natural scenes which are exhibited and sold all over the world, and which incorporate all of the Graffiti Techniques that hes honed over the years. Yeah, over time you really understand what the can is about to do. You know, you come to rely on these tools, like the nozzle or the weight of the can. Like the way that i use the edge there to keep one edge sharp and one edge faded, then this, you know, different lines, adding colours. So theres a lot of disciplines that go through painting that are the same here, you know. Years of practice. No, we dont have that kind of patience. So could we pull off something similar to this by combining technology with someone who has no creative talent whatsoever . To find out, we sent nick kwek to estonia. Tartu, estonias second largest city. Like most cities, graffiti and street art provoke around every corner. If you know where to look. Its also home to one of the biggest spray painted pieces ive ever laid eyes on. But alberts been Painted Dot By dot, and ive been promised i too can achieve artistic genius with the right tools. Believe it or not, these pictures have all been painted with spray paint. Theyve been pieced together splodge by splodge by the sprayprinter device. My daughter wanted a unicorn on her wall, but i couldnt draw. So that pushed me towards creating this device. To make these magical masterpieces you need the right kit a smartphone with the appropriate app installed, an external battery pack to keep it fullyjuiced, a tripod to hold it steady, some paint, and of course the sprayprinter. First you select an image and align it against the area you want to paint. So the image is projected like a giant virtual sticker. Portraits with shadows work best. The phones camera exposes for the led on the device, and when it illuminates, it sends the cans location to the app. The phone then tells the printer its coordinates and the printer decides when to spray and when not to. Once you get the knack of it, its actually surprisingly simple to use. You just have to make sure you go from left to right, or right to left, very smoothly, in a straight line. For all its geeky brilliance, its a real labour of love. Even the most simple of designs takes several hours. Depending on how complex the picture, and the size, the amount of layers, the different colours you want to paint with, you know, that determines how long doing one of these is going to take. You need to move your hand relatively steady, so if you start moving your hand very quickly youre losing accuracy. Not sure i could really stand your for several hours doing this. With the next model, you should be able to move your hand relatively freely as you would with a regular paintbrush. To give your arm rest, the team have already started developing robotic versions to do the spraying for them, meaning larger more complex images. I developed this extra accessory for the sprayprinter to atomise the process, because for high scale images the hand held method takes too much time and effort. Soon, others will be able tojoin in too, hopefully speeding things up a bit. But does the printer help artistic expression, or simply kill it . A person who cant draw at all, this gives like guidelines of how to paint. Its like sort of a colouring book, but you can go over the lines, but the paint will still only land in the right places. I think for people like myself, we call them artistically challenged. Laughter and i think this device gives them new power. The finished result . It started off only a few small dots. You actually have to stand back a few feet to get the full view, to get the right perspective on it. How good is that . So what would you like to see spray painted next . Well, the guys have been holding a competition and this winning submission, just announced, will soon be painted on a local giant abandoned Power Station Chimney for all to see, but painting on this curved structure has posed new problems, which mihkel is determined to solve. I thought it would be a good idea to use a vacuum rover, so this is just a four wheeled platform that drives across the wall. It attaches to the wall using vacuum. Yeah, and in true blue peter fashion, heres one i made earlier. Yeah, all me. Entirely done by me. All of it. Well, that was nick kwek with the sprayprinter. Graeme, worried . Not really, no. I mean its a great tool. It works like a projector. It helps us to get these large images up easier but no, i think im quite comfortable in what im doing right now. I might use it one day though. It definitely has its advantages, for sure, yeah. Well, in the meantime, this is beautiful. Thanks so much for doing this for us. Thank you. Were going to stay on and art tip now. Over to lara lewington. Here at photo london art takes many forms. But the thing ive seen that ive grappled with the most is the idea of a Virtual Reality gallery. Is this really a way to fully experience art . This lot certainly seem to be engrossed in the experience. So whats going on in here, and in here . Well, in the 1800s when people saw photography for the first time they were absolutely wowed by it, but of course now we are a little harder to impress. So whats happening is some of those initial images are being brought back to life in Virtual Reality. Here in this room, the birmingham gallery where fox talbots original photographic images were shown has been recreated in vr. Well, initially i wasnt sure that looking at these images in Virtual Reality seemed like something that actually makes sense, but apparently you can pick up the images by holding your hand over it like that, and then you can hold the image in your hand. Ok, thats pretty amazing. You can really see the texture of it as well. This genuinely feels like im standing in front of a fire. In fact, it actually feels quite hazardous because you can see smoke coming off it and that is proper serious heat. Oh, theres a mouse oh, no thee mouse actually looked so real but whilst the juxtaposition between the origins of photography and a new visual medium are deliberate, making sure it provides a meaningful experience for those with a yearning for art has proved a challenge. Nothing fills me with a greater melancholy than going into an exhibition and seeing somebody with a Virtual Reality headset on, and having to queue and wait for your turn on it its just not very stimulating. So what ive tried to do in this installation is to make that part of the actual experience, so when youre not in the room you can look at people with their headsets and backpacks on. Watching the goings on of people wandering around is quite strange and surreal to look at, so hopefully its still interesting as an artwork even when youre not in the headset. So i can hear some sound coming from over here. Thats because of the binaural sound thats built in, and there seems to be something happening outside. I believe this is the chartists revolt. This is a lot of people objecting to photography. This wasnt the only vr at the show, though. One family of Art Collectors wanted to virtually take their wares out of storage. You can have your art museum in your pocket. I can have 200 metre museum just in my laptop. That could be sharing a collection internationally, a trip to a virtual art gallery for those who are housebound, or introducing a new audience to art who might be more tempted by the vr element. The real life version of this statue is 15 metres tall. I will head towards it and have a closer look. I can actually see the size of it by those people walking around. And in fact the size of that piece of art behind it, the scale of all of this, is absolutely massive. It would require such a large building to actually house all of this stuff. Amidst the physical art were the latest techniques in holographic imaging, entire film is superimposed on single images, and this paris park scene. So behind this photograph we are looking at here is actually a massive plate of led lights, all spread out with an inch between them, so each time you can see a person crossing the screen its actually a combination of these lights being dimmed in that pattern, and what the human eye fills in in between to make it a complete opaque figure. Amazing. One thing that seemed clear by the end of the day, though, was that vr can feel a natural part of an art show, and that im never going to be an art expert. Elastic bands, and bulbs . That was lara. One of the brilliant things about working on click is that we all get to achieve our Lifetime Ambitions at one point or another, which is why this week mark cieslak became the captain of a starship he took some of the rest of the click family with him, to boldly go where no mark has gone before. Space, the final frontier. These are the virtual voyages of the bbc click team. Our mission to wear vr headsets and discover strange, new technology, and boldly go where no tv reporter has gone before. Virtual reality game star trek bridge crew brings together up to four players, each taking a different role on the bridge of a starship. The beauty of going where no one has gone before is that Starship Travel involves an awful lot of sitting down. Sitting down is great for Virtual Reality because the headsets have got these cables. If youre moving around it easy to get caught up with them. Sitting avoids all the flat. And where better to be sitting in the captains chair of a Federation Starship . Headsets on, its time for the click team to become a starship crew. Wow. Its really strange. Thats brilliant. Incredible. Oh, my goodness, mark hi. Im dabbing. All right, people . Lets trek some stars. The Early Missions are all about orientating us with the bridge and how we interact with it. As helmsman, you are the ships navigator. The headset shows us what the bridge looks like, but the playstation Motion Controllers allow us to interact with the various controls we have to master in order to fly the ship. Help. Yes . Warp course to gamma hydra. Engage. Oh, were warping, everybody. 0h wow. Thats pretty, isnt it . Thats good. Wow. We dont have time for sight seeing, though, as we receive a Distress Signal from a stricken vessel. My vessel has lost all power and our Life Support Systems are nearly exhausted. Here we go. Scanning now. Get on that scan. Ok, so, engineering . Yes. Can you transport the survivors to here . I dont know. Chuckles that wasnt in the training. Laughter were homing in at an alarming rate, captain. There are no options within transporter. It says right there in the list. Transport, energised. Its at this moment that the action takes a turn which will appeal to star trek super fans. Ok, guys, this is the Kobayashi Maru scenario. This is an impossible to win situation. 0h its a d51 cruiser. Its a klingon d5 cruiser . Yes. 0k. Target it. Bring it about so we can actually see that the vessel. Bring it in behind it. Come on left, left, left. Turn it, turn it, turn it. Behind us. Operating. There it is. Ok, bring in those torpedoes. Line up the phasers, and torpedoes away. Get us back behind it. Target destroyed. 0h yeah, everybody, we just violated a peace treaty. Wow. Oh, wow. Its pretty warm work being in Virtual Reality. It feels like its social vr at its best, really. Communications a must. If you dont have it youre not going to complete the mission. Great for team building. I thought we actually had our lives on the line for a minute. That ably demonstrates the power of teamwork. Its really, really important that everybody plays their role on the bridge, because if you dont then chaos ensues. We had a couple of sticky moments there, but i think we managed to pull it back and keep it together as a crew. And the result was a successful mission. Brilliant. That was mark and the crew. Thats it for this week. Follow us on twitter at bbc click. Or like us on facebook, too, where you can see lots of extra content and videos. Now, while youre watching this we are doing a live show at the hay Literary Festival in wales. And next week on the programme you can see a little bit of what were getting up to. Cant wait. And if youre coming, i hope you enjoy the festival. And we will see you next week. Good morning. London may not have been the sunniest place across the country yesterday, but it was the warmest with highs ofjust over 23 degrees. I expect over the next couple of days, the south east will get warm, if not hot, as we drag warm air in from the near continent. This slow moving Weather Front will bring a contrast to the far north and west. It will be a mild start for all, some mist around, especially close to the coast. That Weather Front is a slow moving affair and will bring rain into Northern Ireland and scotland, lingering for much of the day. Cloud, largely dry, and more in the way of sunshine across the extreme south. Despite some Afternoon Cloud into the South West Part of wales, temperatures 18 22 degrees, reasonable. Highs of 25 widely in the south east corner, and stretching into the north of england. A different day for the north west, in the lake district, isle of man, Northern Ireland and western scotland. Here it stays cloudy and wet for much of the day with a scattering of showers into the far north east as well. This Conveyor Belt of rain sitting across the irish sea, affecting the western fringes of wales. To the south and east, it stays sticky overnight. A milder feel with widely mid teens across the country. It means that on friday, we gradually start to see change. A level of uncertainty as to how quickly that Weather Front moves eastwards. Hopefully improving through scotland through the day. The front sitting on the spine of the country by mid afternoon. It stays very warm, if not hot, in the south east. 27 degrees, much fresher conditions beginning to follow behind. That is the general theme as we move into the weekend. Significant thunderstorms are likely across the near continent but the Wind Direction moves to a fresher westerly feel. A good deal of dry weather with a scattering of showers for the weekend, but look at the difference. 16 17 in the north west, highs of 22 in the south east corner. On sunday, a similar story. Fresh with a scatter of showers and a touch of breeze. In case you dont have the message, this is the story for the weekend. A scattering of showers and a fresh feel for all. Take care.
