And Artificial Intelligence meets its greatest challenge in the 1980s. siren sounds radio we have one party down. In the united states, Mass Shootings are something that occur with depressing regularity. Libraries, churches, cinemas, and schools all locations of acts of mass murder. Often perpetrated by one individual, with powerful military style weapons. In the last four years there have been more than 200 Mass Shootings in schools alone in the united states. The Deadliest School shooting ever was in 2012 at sandy hook elementary school, where 20 children and six staff were murdered by a lone gunman. It made headlines across the globe. And so to help prepare for the next time, authorities have turned to technology that is normally used in video games, to help train emergency crews and even teachers to be ready to respond. Just a warning, you might find some of the images in this film distressing. Radio at least one person has been shot. Hundreds of people just running around. Lam frightened, and i know that my constituents for the most part are frightened. Radio we have a weapon, he has shot. Unfortunately these active shooting situations, particularly in schools, are not going away any time soon. Youll see in schools, they do more fire alarm drills than they do active shooter drills. Thats changing now in some schools. The most recent School Shooting in the us was just a few days ago, in spokane, in washington state. A High School Student died confronting the shooter. The department of Homeland Security is try to do something the department of Homeland Security is trying to do something about these events. There have been a lot of copycats, that have necessitated First Responders getting more prepared to respond to these kind of attacks. So its created a simulation to help train First Responders to what it calls active shooter attacks. The simulator is called the enhanced dynamic geo social environment, or edge for short. It is a video game that is very similar to popular first person shooters. Using a pc, a team of First Responders can Work Together to resolve an active shooting incident in a hotel. Fire teams put out blazes, paramedics treat the injured and cops deal with the bad guy. Orlando in florida is a hub of serious simulation and training activity. Teams here create advanced simulations, including using animatronics to teach medics how to deal with soldiers injured by ieds. This facility is part of the Army Research labs. They are primarily concerned with Building Research and training the military. It is the birthplace of the edge system which we can see through here. Designed in conjunction with simulation specialists cole engineering, the research lab has used the unreal engine to create its environments. One of the reasons we connected with the department of Homeland Security is that we have a lot of experience in the simulation world. One thing that we have been moving towards is the use of game technology, to provide those capabilities that traditional simulations did in the past. Time to try edge for myself. I can play as a firefighter or medic, but i will choose to play as a cop. To make the training is useful as possible, the active shooter is played by a human being. This produces an unpredictable element that an ai would find difficult to replicate. This feels like an ordinary videogame graphically, and the way it plays. Actual First Responders would play this game, applying their real tactics and procedures to the situation. I can see the bad guy. I will fire at him now. I managed to take him down. While the hotel might feel like playing in a normal video game, the team here has been working on a new environment, one with far more chilling connotations. A school. When there is a School Shooting, it is completely different than when there is other types of soft targets hit. And its very different than a traditional, if you have an active shooter at a mall or a theatre or somewhere like that. And a new Playable Character has been introduced into the school environment. As well as cops, the player can take the role of a teacher. An active Shooter Event in a school, has it been discovered then, that by the time Law Enforcement arrive, the event is over, that the shooter has killed people in the school . Thats correct. Basically the teacher is almost the first line of defence for the students, to stay safe. So i have spawned in and i am a teacher in a classroom. Here are my kids, i can definitely hear gunfire. I have a list of instructions that i can give to the kids, in this instance i think the safest thing to do is tell them to get out of the school completely. This classroom has windows. I have barricaded the door to the classroom, you can see the shooter outside, he is shooting at the barricade, i have evacuated all of my pupils from the classroom. My class has survived, but the experience is an unpleasant one. This is definitely not feeling like i am playing a game. For my final experience with edge, i try the role of the person conducting the training. This means i have to play as the school shooter. We work with specialists in this, and we have also talked to people from sandy hook, we have studied incidents at multiple schools. If anything it seems really quite horrible, shooting innocent, unarmed children. It really is quite an unpleasant experience. I have to admit this was very difficult work for us, most of us have children, and to dig deep and understand what type of stimulus teachers are going to get from an event like this, what are they going to see, what are they going to hear. Im actually hoping that the cops turn up quite soon, to be brutally honest. Can you bring the cops in . Yeah. What has been the reaction from the world at large to the notion that an Army Research lab is building Simulation Software to assist Law Enforcement to deal with School Shootings . Honestly, it is mixed. We have some people who are very concerned that if we have a scenario like this, it allows people to train to attack the school. The truth is, thats impossible. The scenario is completely controlled, so that only the people who administer the game can invite people into the scenario. Homeland security is securely making the system available to First Responders, and soon teachers, for free. While orlando is home to the arl, it also knows the carnage that can be wrought by a lone gunmen. This is pulse, it was a gay nightclub. Last year it was the site of americas deadliest shooting. Omar mateen, a lone gunman, armed with a pistol and an assault style rifle killed 49 people here. In the wake of the pulse shooting, Florida State senator Linda Stewart tried to introduce a bill limiting the sale of new assault style weapons and large capacity magazines. The bill did not pass. Homeland security has commissioned this Simulation Software, which is to train First Responders and Law Enforcement, in how to deal with active shooter situations. What you think about that bit of software . I think its absolutely necessary. I think that the more hands on, or the more information that people who are having to respond have, the better they will be able to respond in real time. In the meantime Homeland Security is hoping to create more environments for edge, eventually building a generic anytown usa for virtual training. I dont think we can necessarily stop these events, but hopefully we can reduce the number or the severity of these attacks. Hello, and welcome to the week in tech. This was the week that apple launched a new phone or two more later in the show. The two year legal battle over the ownership of a monkeys selfie finally ended. Long story short, it is not the monkeys photo. The department of Homeland Security in the us has ordered all departments to stop using software from kaspersky labs, after potential ties to russian intelligence services. The companys founder has denied any connections, and says they co operate with authorities around the world. A 3d printed structure has been shown that can fold itself up without the aid of heat or water. The team behind the structures believe it can be used to create printable robots. And speaking of robots, six months after its debut in california restaurant, flippy the ai burger flipper has apparently done so well it will be rolled out to over 50 other fast food locations in the states. Flippy uses cameras and sensors to see the world around it, and apparently cooks the perfect burger every time. And of all the jobs we thought robots would take, classical conductor was pretty low down the list. However that is exactly what happened when this robot conducted Andrea Bocelli and this orchestra. The robot can only repeat the movement of a maestro, and cannot respond to spontaneous tone or tempo change in music. Its unbelievable that it was only just over ten years ago that stevejobs said this. An ipod, a phone. And we are calling it iphone. applause . The iphone did something no smartphone had done before. It really brought the internet into our pockets with its high quality, big touchscreen, a good browser and that great idea of pinch and zoom. It kickstarted a new generation of smartphones. It defines the look that every other smartphone still adheres to, and in the process it made apple the most valuable company in the world. So when a new iphone arrives, the world pays attention. We did too. David lee was there. Say hello to apple park, or the spaceship, several call it. Eventually, 12,000 people will work on this 175 acre site. It was designed by british architect Norman Foster and cost a reported 5 billion, which makes it the most expensive building in america. Their headquarters is in many respects the last great project from steve jobs. This was his final appearance in public before he died. One last launch not for a device, but for a building. So its curved all the way around. You know, if you build things, this is not the cheapest way. There is not a straight piece of glass in this building. Six years later i am among those piling into the steve jobs theatre, a purpose built venue for the kind of product launches that he made his trademark. You wonder what he would have made of the latest iphone. New facial Recognition Software means you can unlock the device just by looking at it, a system that replaces the fingerprint sensor in previous iphones. After a bit of a mishap, apples Craig Federighi got it working. And this might be the most ridiculous orfine use of Sophisticated Technology ever. Its a happy puppy. Check out the physics of the ears. Animated emojis track my facial expressions to power the emoji with different expressions. This makes me laugh. I can do these pig and if i smiles, it smiles, and it might raise my eyebrows and puff my cheeks, it does that. At 999 or £999, the iphone x does not come cheap, which is why apple is also bringing out an iphone 8 and 8 plus, a more incremental upgrade on last years models. And for the first time for an apple smartphone, it can be charged wirelessly something samsung, it has to be said, has offered since 2015. The iphone 8 pluss camera offers a way to artificially change the lighting on the picture which it does by using the two lenses on the back to digitally simulate different lighting conditions. And the apple watch has been given a significant upgrade. It now has its own Cellular Connection built in, which means you dont need to take your phone with you in order for the watch to work. It is sales of the iphone which have made apple the huge, huge company it is, and the new h0 is a permanent reminder of the companys enormous power. Will the iphone x continue the success into another decade . Apple seems confident but then again, they might be talking with a emoji. If you wonder what humanity would do if given access to the most advanced facial tracking technology available, you now have your answer. This coding school in paris has no teachers, no syllabus, no hours and no fees. So what does it have . Ecole 42 was created in funded by a french billionaire and entrepreneur xavier niel. He felt the french Education System could do better, so he created this place for i8 30 year olds to study coding, and effectively teach themselves. This was a concept he already launched in san francisco. It was a mix of several methods, what was done and implemented in the finnish educational system. It was very much searched and researched and it is a model that has been tested and implemented here. Land in place on the course is the first challenge. 50,000 applicants get whittled down to 3000 for what they call that the la piscine state which doesnt involve swimming, but a metaphorical trial over whether they will sink orswim. Only up to 900 will make the grade. On the first day, we dont tell them anything or give them anything. They have to figure out what to do, they have to go find a room, how to work. Those taking part dont even know what they need to do to impress but they are aware that its their peers assessing them. There is no lectures, essays. You dont quite know the information so it takes a lot of trial and error, but it forces you to speak to your peers, is that there is a lot of exercises and working with your colleagues. It is really a 2 way thing. Its notjust me asking them to help, thats learning to all of my questions. Ive seen some people who come here just for fun, and funny is not why we are here, we are here to work and improve. It seems to be a friendly place. Far more sociable than i expected. One of the main aims here is an educational meritocracy giving everyone, no matter their background and achievements to date, equal opportunity, and for that reason, a place to sleep is available. While undertaking the course trials, some mayjust use it for a nap in the day but others could be staying there throughout the four weeks. A lot of the work happens between 2am and 3am in the morning and the place is quite busy. For me, because i dont have a salary, it is good to stay in here. But for those who make it onto the full course, 80 gain employment while still studying with 100 getting jobs by the end. I think the really special thing about the school is the ecosystem where everybody who comes here is super ambitious and super motivated, and being surrounded by people who have that kind of mindset really pushes you to perform better in life. Its amazing what you can achieve when you teach yourself. And thats also true when a computer doing the learning. Artificial intelligence has been making Great Strides recently and some of it has involved something that would have been frowned on here. Video games. But the truth is, games can actually be very educational. For us, but also for machines, because they are being used to train Artificial Intelligence is to solve problems. There are simpler environments that are ideal. They have small sets of rules and commands, the scoring makes it easy to judge how well the ai has done and problems can be played out over and over again. Different types of games can train an ai in different ways. For example, this is go, a boardgame with simple rules, but it has so many possible moves, even a computer cannot number crunch its way to victory. So Googles Alphago developed its own playing style in order to beat the human world champion. But a Platform Game teaches a machine more about the physical world, about timing, how to move, how to prioritise different tasks. There is one Platform Game which strikes fear into the heart of many 80s gamers. And it is one that a group of students in california have decided to take on their own home grown Artificial Intelligence. We went to meet them. Walkaround, find a commodore, walk around, find the key, die, repeat. This is essentially what you do when you play montezumas revenge, and it can be very frustrating. Please, no. Montezumas revenge is considered the hardest original atari game, in part because there are so many obstacles to avoid and so much you need to do before you get any high score. These three computing students from Stanford University were looking for a College Project that our natural language processing course. When they heard googles deep mind project was trying to beat atari games using the ai system. Intrigued, they tracked down squashy from 2015. The graph is impressive, you have games like breakout or pong where the agent is beating humans by a factor of 1000 but there is a game at the bottom with atari says 0 and we were curious about that, why is it doing so badly . 0 , means the ai got a score of zero no matter how much they trained in that game is montezumas revenge. We played it and we almost got close to 0 . It is a really hard game. But as enthusiastic students often do, they wanted a challenge. Googles deep mind scoring zero meant nothing. Lets create a system that can beat the game from our dorm rooms, they said, so they did, building an agent which would follow simple human instructions in order to play the game. We can describe in english exactly what instructions we would give you. We can pretend you are the ai. The first thing we say is, dont die. That is brutal. Which in all honesty, it is something it takes the agent a while to discover. Did you actually say, dont die . Yes, and it makes things better. So they trained the ai to follow human instructions, dont die, go left, jump across, for example. Then they gave it a reward. The same way you might incentivise me to fold my laundry by telling me i would get 10 for doing it, we give the agent 10 in its own currency for solving the task we ask you to do. Then as is so often the case with al, it started to do its own thing. We thought were being clever by telling it to go down the ladder to start up again because that is the path to the key, and that is what you need to win. The agent wants to follow the instruction but it also wants the key because the game gives it a bonus. And it can go down the ladder a little bit and then ignore our instructions and jump. We thought our algorithm was broken. It points to one of my fears with Artificial Intelligence more generally. Sometimes when we describe what we want, an agent can interpret it differently. And that can have devastating consequences if the actions are more serious than steps in a videogame. What is exciting about this ai system is how the students envisage it being used out of the game world and in real world. Whoever said playing games in university is a waste of time should really take a look at what the students are achieving. That is it this week. Dont forget, we live on twitter on bbcclick and on facebook too. Thanks for watching, we will see you soon. Hello. The very same weather system that produced a very wet wednesday in Northern Ireland is gradually pushing further east across the uk during thursday. Here it is. At least to begin the day, there will be heavy rain bursts in western areas. We are looking at things at eight oclock in the morning. You can see it in the west of wales into south west scotland. All points east of that should be fine and dry. A mild morning compared to wednesday. But the overnight rain is pushing away from Northern Ireland. Something sunny not far away. It is a bit lighter the further north you are. Some of us in eastern scotland will start the day dry. It is very slowly going east. Even by the end of the afternoon it wont be into Eastern England. Ahead of this weather system, in some sunshine, feeling quite cooler. But the sun will come out. Northern ireland, scattered heavy showers. Some pushing in the western parts of scotland through the day, especially into the western isles. That weather system is just creeping into western parts of Eastern England that stayed dry on thursday. Thursday night, a chilly night into friday morning. Widely into single figures, low single figures in some spots, a few patches of mist and fog. Northern ireland, another system of weather coming in with rain. A gale in the irish sea. That rain is gradually edging into other western and northern parts of the uk into friday. Again, leaving much of central and Eastern England dry. Pulling away from Northern Ireland, with sunny spells coming back. The weekend starts with a frightening area of low pressure, but most of the energy is pushing away to the north. A weaker weather front heading our way slowly as the weekend goes on. A gale in places. A mild breeze blowing elsewhere across the uk. Sunny spells developing from the south. The odd spot of rain shifting northwards through the day. A weather front weakening in the west of the uk. Ahead of that, well see the higher temperatures. Some spots are into the low 20s perhaps. Hurricane maria is out of mexico and is moving close to the north east coast of the dominican republic. It could be a major hurricane cloe to the turks and Caicos Islands by friday.
