toxic gas and lava flows from the mount kilauea volcano. at least two homes were destroyed when lava bubbled up through fissures in a residential area. several strong earthquakes have shaken the southeastern region of hawaii's big island. president trump has addressed the national rifle association and vowed not to tighten us firearms laws — despite suggesting after the florida school shooting that he was prepared to take on the gun lobby. he again called for teachers to be armed — saying any gun—free zone was an invitation to shooters. the palestinian leader mahmoud abbas has apologised for comments he made that were widely criticised as being anti—semitic. at a meeting in the west bank on monday — he suggested the historical persecution of europeanjews had been a reaction to their financial activities, not their religion. steven gerrard has been appointed as the new manager of rangers. the former liverpool and england captain,

will take over in the summer on a four—year deal. it's his first step into elite management, as our sports correspondent natalie pirks explains. crowd chanting. steven gerrard is well used to the spotlight, but never before as number one. in the end, it was the butterflies that got him. it was a no—brainer for me. there were a lot of things to think about, but from that phone call i got a special feeling, and i knew rangers was for me. rangers‘ chiefs say gerrard's ability and character outweighs the inexperience. he certainly had ability in spades. a 19—year playing career brought him nine major trophies and 114 caps for his country. since retirement in 2016, he's been coaching liverpool's youth teams, but despite a massive first step into the glare of management, fans at ibrox believe they've got the right man.

a wonderful aura, rangers need a leader and we have been lacking a leaderfor a long time. he's a winner and rangers deserve to have winners. we're looking forward to him being part of our establishment and our good team, and hopefully the future will be bright for us. we need to stop celtic, we need to stop celtic now. we are the people! and that's gerrard's biggest task — restoring rangers to their heyday. in liquidation just six years ago, the club has promised to back him with the cash he needs to break celtic‘s stranglehold on the scottish premiership. his former liverpool manager brendan rodgers led celtic to the club's seventh successive title last weekend. i always say when i welcome new managers into the job, it's welcome to the land of no sleep. it's a totally different experience, but you only get that through doing it. i am very much sure he will really enjoy it. of course, he'll want to do well with his team, and that's the only thing i can't

wish him the very best with! i just want to win football matches. that's what i love doing — that's my buzz. that's what i want to do here and that's the demand here and i am ready for that. he'll need to translate that passion into points — and soon. now on bbc news, it's time for click. this week, the data that might keep the streets safe and keep the high street in business. plus, some beautiful music that won't scare the sheep. we are becoming aware of how much

data we give away without even realising it. our habits online can say a lot about our personalities, but when we are out and about, what does our behaviour in the real world say about us? well, in the uk, we're all getting used to the fact that we are being filmed by cctv a lot the time. but although a human can tell a lot about a person just by looking at video footage, that is a really ha rd at video footage, that is a really hard job for a computer to do. that said, this system is having a pretty good guess at who is looking at right now. it's a very flattering guess actually, but probably no worse than a human would guess given the same footage. this system is an artificial intelligence that researchers at southampton university have trained to estimate the gender, age and a description of eve ryo ne the gender, age and a description of everyone that falls under the gaze of their test cameras. we have millions of images, different types of people captured from different environment, from all around the

world, and we hand label these. they are labelled by human beings as male, female or 16— 30, and the magic card is that we can feed these into a machine, into a computer, to learn what it means to look male, what it means to look female, just from the visual cues alone. the team at pitching this at retailers, as an improved way of measuring footfall, instead of just improved way of measuring footfall, instead ofjust counting the number of customers who come into a store, this can tell shopowners whether the right kind of people, the shops' target audience are being drawn in. rather than know that 100 people came in and we sold 50 things, we can tell them that 50 people on their target demographic came in and they sold 50 things, so now they know how they are converting certain types of people who they are converting. 0r types of people who they are converting. or they can tell them that their sales are down even though people came into the shop, they are not selling as well because they are not selling as well because the right types of people aren't coming into the shop. retailers would get a breakdown through each day of the most popular spots in

store and the most popular routes taken through the store by each type of customer. and with this high street here guess, you can see which shopin street here guess, you can see which shop in doughs are more grabby and how long people dwell on different areas. in this example we can see carphone warehouse actually has a higher proportion of females walking past it then gap on the other side of the road which might indicate that maybe gap should move their placement along the high street has decided the street sees more of its target demographic. this kind of profiling of humans by computer systems has many uses, from this kind of a non— eyes resale analysis, to other areas that my say more about us as people. —— retail. 0ne of the more controversial uses for ai is in policing. we travelled to durham to find out more. peterlee police station in county durham. the early hours of the morning. the man pictured here in the station's cctv,

let's call him steve, has been arrested for possession of heroin. arrested on possession... here in durham the police are trying ai softwa re durham the police are trying ai software which could help make decisions about suspects being held in custody. after steve has been processed, the custody sergeant will enter his details into a system called bahama system at risk tool. it is designed to help custody sergeant make rules —— decisions about what to do with the suspect. what it does algorithmically, it uses all of our data to tell us who is high risk of reoffending, medium risk of reoffending, and low risk of reoffending. it is not absolutely perfect, but it gives us a really clear indication of who might commit crime in the future. the aia is trying to identify repeat offenders

who, rather than being centre court, will be entered into a rehabilitation scheme called checkpoint. we recognise that we place offenders into the grille justice system there is a role —— revolving door so it wanted a look at is there a better way, is there a different way, that can produce more positive outcomes. this is the first time in al system like this has been used in the uk. so what is the process than? i put my name in here... the system is now searching for the prisoner, this item will click on the list, the system will decide imo risk of detainees at and the sergeant would be presented with... " low-risk, the subject is not likely to treat an offence in the next month. " so the sergeant has decided this person will be remanded in custody, will be refused bailand go to remanded in custody, will be refused bail and go to court the next morning. it is a different story for steve. he has a long list of

previous convictions including drug possession, are salt and driving offences. the ai assesses the data at —— that durham constabulary holds on him and make this recommendation. he can only enter checkpoint if you make it as a moderate risk. a final decision around steve being centre court or entering checkpoint rests with the custody sergeant. we will continue to use our nose in our gut like we await have done, but what he hart doesn't have that is, we have looked at ten years of data and that allows us to see who will commit crime in the future. everyone who works with the hart project i spoke to is keen to stress that the information it provides is advisory only and the human custody sergeant makes all the final decisions. but the use of this technology in

general is, for some people, cause for concern. this kind of artificial intelligence system in policing relies on big data. and that means people's privacy is at risk, and it risks us moving more towards a surveillance state. but it also risks discrimination, because patterns that exist in data already risk being perpetuated and repeated. and there is very little accountability over it. cambridge university's criminology lab is the birthplace of technology being used by the police in durham. it has been in development forfive by the police in durham. it has been in development for five years. the decisions that hart makes are based on historical data. it uses this information to predict the future outcomes. barrass official intelligence —— our artificial intelligence, it is looking to the past and the pattern —— patterns we have observed, and looks to the

future. we know that passes not perfect, humans are making decisions and humans are making predictions in the criminaljustin ‘s system. and humans are making predictions in the criminaljustin 's system. -- justice system. this is a misuse of the four different rictus which include things age and gender, but it also uses data from the credit reference agency, and it is this data that privacy campaigners find troubling. the data profile individuals based on their postcode their household and even down to an individual level. and some of these profile stereotypes include terms like" disconnected youth", "asian heritage", things are —— people are sorted into these categories. that is bad enough, and that kind of profiling is being used to make decisions about freedom and justice in the uk. i think we need to put the brakes on and say, why are we doing this? it turned out that

experian variable was highly important, if we were removed from the model we would have lost a lot of accuracy. i will say that we are now about to install the next generation model which will not use this code. it isjust a contractual reason. the durham constabulary's contract with experian has come to an end. back in peterlee's police station, steve has been assessed and accepted into the checkpoint programme. he and spending around eight hours in police custody. programme. he and spending around eight hours in police custodylj will eight hours in police custody.” will grab eight hours in police custody.” willgraba eight hours in police custody.” will grab a stuff, come round the front and give you a lift. what is the future of this kind of technology? i think over the next five years there will be a proliferation of these kind of tools, i think going forward society will come to accept them or, but the human beings, government, society, needs to stamp its foot little bit about it. and the reason i say that is because we need to have more

regulation. it has taken me about a decade working in this field to realise that the real question is, what i always called the "now what" question. i will build your model that will predict whatever model you wa nt that will predict whatever model you want incremental justice, but that will predict whatever model you want incrementaljustice, but what you going to do with it? ones that box comes back and you have a red box comes back and you have a red box on your computer screen that says high risk, now what? hello and welcome to the week in tech. it was the week in which the world's tallest tower in dubai created a virtualjump tallest tower in dubai created a virtual jump off the tallest tower in dubai created a virtualjump off the top. chu —— should you choose to accept it. iran joined russia and blocks telegram, and with the harvest over, cambridge analytica shut down. ford revealed plan to let the blind see—through car windows. this gadget converts the window to greyscale it then

vibrates light or dark depending on where you touch it. rather usefully, and ai assistant also tells the passenger what they looking at. the boss of whatsapp is off, not happy that owners facebook are trying to commercialise us data. lg had its biggest phone launch of the year, the g7 thinq sports a great camera, with a high predicting which camera you need. and take a look at what could be the most beautiful epic fail ever. this is the stunning display created by chinese firm who broke the guinness world record for the most drones flown simultaneously. the problem is that the aircraft failed to spell out the date and the record—setting number of drones perfectly. an epic fail according to the country's owned south china morning post. tough crowd! so we have been talking about

the power of data. and probably no one has more personal data on une bands you know who. —— you and me then you know who. at facebook‘s conference this week they were telling us their plans for the year ahead. there are new face filters, i wonder where they got that idea? a new vr headset, and a dog on a laptop. thanks, nice work! but there was not just a laptop. thanks, nice work! but there was notjust a dog in the conference centre, there was one very big elephant in the room as well. welcome to f8! and it has been an intense year! privacy has been ce ntresta g e intense year! privacy has been centrestage for facebook so far this year, with mark zuckerberg appearing in person before congress to send facebook‘s privacy practices. the

company is scaring —— sharing the scandal, cambridge analytica, announced it was shutting down, saying it was an vilified by accusations. nevertheless, facebook ros feet are still very much to the fire as questions heat up around how the data is used. what i have learnt this year is that we need to take a broader view of our responsibility. facebook‘s opening salvo, a new feature called cliett history. starting with something that a lot of people have asked about recently which is the information that we get from websites and apps who are using facebook ros advertising and analytics tools. the new tool which will not be available for at least a few months is an attempt to answer some of the harder questions put to him by congress. facebook already offers this tool which let you download the data that they hold on you. the problem is it isn't all the data but they hold on you. my

facebook like items and also using hidden facebook trackers installed by the owners of many websites, facebook and follow you as you browse much of the web and it is accessing this data which is uniting privacy advocates and congress alike. clear your history is misleading, all they are doing is disconnecting the history, the browsing history, from the profile, from the account. the data will still exist and the information that you give to website one, two and three will still exist and be stored in the facebook databases but it will not be linked to you directly but it will be linked to some other identifier and possibly alongside that other identifier will be kept other data about you. and while facebook might not be so lacking in privacy, maybe they could be luckier in love. we are announcing a new set of features coming soon around dating. cheering and applause. now,

this is going to be for building real long—term relationships, all right? notjust hookups. he promised to bare these privacy issues in mind with the new service but would you like the idea of facebook getting even more intimate with you? a few yea rs even more intimate with you? a few years back, wearables became the buzzword. but this set, there has been a lot of talk about here are bulls. that could mean a personal training session or real—time translation. —— hearables. directly into a translation. —— hearables. directly intoa pairof translation. —— hearables. directly into a pair of here i go for earbuds but this we can put into the test a few devices that aim to give you a hearing test and as a result optimised what you are listening to. even to those of us who are unaware of having any effect, the chances are our of having any effect, the chances a re our lifestyles of having any effect, the chances are our lifestyles while had some

effect on a hearing and due to this, the talking things in exactly the same way. “— the talking things in exactly the same way. —— defect. the talking things in exactly the same way. -- defect. we have a huge range of hearing from 20 to 20,000 hertz and there are causes of different type of hearing impairment so you could have a hearing loss through ageing or noise inducement, or disease. it can headphones balance this out and do we actually need them too? i went into one of our peaceful radio studios to find out what. first of all i have the audera headphones. i need to do we hearing test to create my profile. what we're doing here is finding the quietest part my audible range throughout all of the different frequencies. so let's get started. that is it. it takes about ten minutes to go through this whole process for a full range of sound on both ears. 0k, process for a full range of sound on both ears. ok, so the results of my test and i can tell that each year seems to hear differently from each other but beyond that obviously it

doesn't mean a huge amount. but what ican do doesn't mean a huge amount. but what i can do now is put the headphones to the test. 0k, i can do now is put the headphones to the test. ok, so it says the first time you experience this personalised sound it may be very different from anything you have ever heard before. so it is, oh, it also says it may be overwhelming for some people. 0k. sorry if i'm shouting. this is at 0% now. let us apply 50%. well, it sounds a lot cleaner. the sound is a lot sharper. you can hear each element of the sound really clearly. the clarity at 100% is pretty good. 0k, sound really clearly. the clarity at 100% is pretty good. ok, so it optimises the sound and it seemed clearer but also my test is pretty subjective. so what are the experts make of the concept? with the audera, it uses a basic form of pure tone audiology which is something we

perform everyday in the clinic and involves presenting different pictures and tones and measuring how loud we have to make in order to someone to hear it. —— pitches. audera so they take that into account with the settings on the headphones and incorporates giving different sound in the headphones on for hearing loss. the mimi music up works in the same weight and has been around a few years, it optimises the music you listen to through any wired headphones. just inputting your age does the job to some extent, although i ended up more impressed by the way you could twea k more impressed by the way you could tweak the sound around you. here i have the headphones which look pretty interesting because they are in the airand pretty interesting because they are in the air and over a year that they worked differently, instead of asking you whether you can hear something, nurophone earphones to the test for you and they do it in 60 seconds. they claim to do so by sending sound waves into your ear which will trigger a reaction,

sending political impulses to your brain and sound waves back out your year. it is through measuring them that the app creates what it calls or hearing significant. in my not very scientific test, i am noticing the different between normal headphones and speakers, music sounds different, different parts of the music sounds louder. that is mixed in with a real clear, crisp sound. but our expert had some questions over this upgrade of sound quality. they give you the opportunity with the headphones to be able to compare generic settings with those taking into account your personal profile. there was a hugely marked difference between those two things were actually tested them mou, hearing which actually prompted me to go downstairs and hughes are diagnostic test. i saw it i have normally function is, so the reliability of that and the accuracy of how that actually come to those conclusions are not entirely sure.

but what i want either of these over another pair of headphones at the same price? maybe the fact is that i don't need them if my hearing was a little more damaged, they would be great to awards to reap. macro or rewards. lara with that and now we get one of the most dramatic communities the western world, a nation with more sheep than people. but residents they are being given access to a new piece of software to help magnify the musical talents. this is paul carter. when you think of parts of the world innovating in technology, a rocky collection of islands in the north atlantic may not be the first place that springs to mind. but the islands situated between scotland and iceland are trying new ways of doing that. we talk a lot about the power of technology to bring people closer together but what the government here are experimenting with a new

ways to bring education to people across the islands. bringing the world a little closer to them. this from a collection of 18 islands are actually no stranger to technology as well is leading mobile phone for g connectivity in partnership with chinese firm huawei, they are also building a reputation for taking on the tech big guns and winning. more on that later. it is that experiment was tech to enhance their cultural heritage that brought us here. the government has announced it will be making musical education software com pletely making musical education software completely free to all of its 50,000 citizens. so there is only one really special high—level music school here in the capital but people with on other islands can have that so this is a perfect country to use technology to spread music education and musically true the throughout all of the 18 islands of this country and make music accessible to all. the web—based platform aims to teach music in the same way that the language and

claims to be beneficial to everybody from children to people with learning difficulties right up to professional musicians. we don't have access to the big universities or the best teachers in the world. if we are not — if we don't use the digital platforms in any area, you could think of, so we are very proud of the digital possibility for our citizens. it was not that difficult to get the government to do this because we are very proud of being this musical nation, have, like, i don't know, ten brass bands, you know, in a population of 50,000 people. an-26 being the islands made worldwide headlines when its own version of google street view, named sheepview resulted in google mapping the islands for its service. they haven't stopped there. now we have more and more tourists coming who are more and more tourists coming who a re interested more and more tourists coming who are interested in our language. but we we re

are interested in our language. but we were not present on google translate. so we thought that we should give google and other go. we would ask them if they could put our language on google translate. they established the translate and online service that request was sent to foroese vault tears recorded the translations and posted them on a dedicated website urszula is a useful tool to promote the islands they also hoped it would again add pressure to google. try it and you would learn that we have a0 words forfog. would learn that we have a0 words for fog. as yet, google hasn't bowed to pressure a second time. we don't have the budgets that the uk have for example so we need to find something that works for us and this works very well. it gives us the attention we wanted but most of all, it shows our culture and our people. but why is such a rich part of the world so keen to stay connected.

pa rt world so keen to stay connected. part of it to tell all the world that we are here and we have a language and we are a country and future come visiting us or you should go and google us on the computer because we are also here. hello! that was paul impey islands and that is it for us, we live on facebook and on twitter. you can find loads more for us every single day. thank you for watching. see you soon. hello there, good morning. we are expecting to have the hottest early bank holiday monday on record, it should be a cracking weekend, just about everywhere. stronger

winds in the north—west, every now and again the north—west scotland may see rain otherwise dry on saturday, spells of sunshine elsewhere in scotland, northern ireland and england and wales but on the whole, but the rich is a shade up the whole, but the rich is a shade up on what they were on friday. the rain in the north—west of scotland heads towards the northern isles for a while and tends to peter out. again, misty around with these irish sea coast, if few mist patches in land as well and chilly in the south—east corner otherwise it or nine degrees and warming up in the sunshine on sunday. all of the day on sunday, the chances from stronger winds and rain early on in the north—west of scotland which should get away, increasing amounts of sunshine on sunday and those temperatures responding really warm again in the north—west of scotland high into the low to mid— 20s in the south—east and hotter still on monday. welcome to bbc news, broadcasting to viewers in north america on pbs and around the world. my name is nkem ifejika.
