frequent in this disease. nearly all the patients coming through to icu now have this new sepsis, and for the ai, this was an illness it had never seen before, nor had any data on. and remember, just because a computer has learned to be good at one task, doesn t mean it can do a different one. the ai clinician was back to square one. but the humans weren t. their idea was to gather data from icus across the uk to create a database of treatments that worked, so the doctors in the thick of it could learn from each other at speed and save their patients. we build for the first time a picture of how disease was treated in real time on the databases across the country. and you see all see the diversity of all the different approaches people are trying, what was working and what was not working. now this data will be used to retrain ai clinician and one day it may help to treat sepsis that s caused by covid. so it s about 18 months
itjust guesses it doesn t even know what it s getting at. all it knows is when its guess is right and when it s wrong. and mostly, because it s guessing, it s going to get it wrong. and the great thing about computers is they can do this over and over again, really fast, and they remember everything. and every time it does accidentally get it right, it makes a connection to its previous correct guesses. with every right answer, certain connections get stronger. and with every wrong answer, others get weaker. through this barrage of guesses a network grows, similar to the human brain, which starts to distinguish between right and wrong. a digital thought process that we call a neural network. until eventually, after a multitude of attempts, it has very few failures and a lot of success.
issue. there are some people who believe it s an asset to the nhs and we should sell it, there are other people who believe that in some way or another that s a wrong thing to do from a moral point of view. but if we get it right and it is a big if the benefits could be huge. a unified joined up store of medical data could really speed up research and lead to new treatments. and ai would be used to look for the patterns hidden within. and that s something that could soon be helping those who are suffering from long covid. thanks to artificial intelligence, we were able to link patient records with imaging and produce an analysis of 41,000 patients, imaging and clinical associations in about two months. adriana roca is part of a team that has been looking into why long covid only affects some people.
