Hello there. on tuesday, we saw a definite east west divide across the country. eastern areas saw the best of the sunshine and the warmth. further north and west, it was windy with outbreaks of rain and felt fairly cool for the time of year. now, for today, it s going to be one of sunshine and showers and it ll be less windy as well. the reason for it the centre of this low pressure system will be just pulling away slightly from the northwest of the uk, so we ll have fewer isobars across the charts, but still some weather fronts which will bring outbreaks of rain. the overnight band of rain will be slowly clearing away from eastern england and eastern scotland. it will do by around mid morning, of sunshine and showers, and into the afternoon, some of these showers could turn out to be heavy and thundery across some northern and western areas. probably the best of the sunshine across the southeast. winds will be lighter these are mean wind speeds much lighter than what we had on t ....

There s an ai, machine learning element to the process. how does that work and what are the cameras looking for? detection of people is reasonably straightforward. the cameras will do that themselves. the tricky bit is, what is rubbish? rubbish in one environment is not rubbish in another environment. the cameras collect a lot of date of movement in the environment. data scientists will look at that and make sure we tag and review the footage and making sure the right thing is being tagged, are we getting false positives or false negatives? trying to minimise those elements so that what we see is accurate. so you re actually using a little bit of a human element to teach them context. that s quite a difficult thing for an al to learn on its own. vision technology can identify what a box is or what a mattress is, but it doesn t know whether that s good or bad. i can see shadowy figures dropping off rubbish. ....

For an al to learn on its own. and i think that s a really good way of putting it because vision technologies can identify what a box is or a mattress is but it doesn t know whether that s good or bad. so, we ve got some images on the screen here of some shadowy figures dropping off some rubbish. i can see that it s got a green box marked around there, so what s it identified? so, what we re seeing here is this is part of one of the automatic ai computer vision models that we re using. this is detecting that there s some rubbish that s come into the scene of the camera, and there s a person pushing that rubbish along you may recognise him! chuckles and you can see down the bottom here, so the model has detected at a level of 68% accuracy and it s opinion that that is rubbish. i d say that s pretty accurate, yeah. yep, yep. and if we look at other instances, there s one here which hasn t been matchy matched. so, now, this is the same trolley, so in theory, this should ve actually been ....

And what are they looking for? detection of people and that sort of thing is reasonably straightforward, and the cameras will do that themselves. what is the tricky bit is what is rubbish? it s quite an objective thing, isn t it? yeah. rubbish in one environment is not rubbish in another environment. the cameras are installed, they collect a log of data of movement in that environment and then, our data scientists will then look at that and make sure we tag and we actively review the footage and make sure the tagging is correct. so is the right thing being tagged as rubbish and not rubbish? are we getting false positives, false negatives? and trying to minimise those elements so that what the customer sees is really accurate. so, that s really interesting. so, you re actually using a little bit of a human element to teach them context? that s right. which is quite a difficult thing for an al to learn on its own. and i think that s a really good way of putting it because vision techno ....
