AI

Elegranf I think we may be talking at cross purposes. The photos were taken by a technician using a special high resolution camera at a clinic. These were then uploaded and analysed by an AI machine located somewhere else, which then generated a report for the NHS. I've no doubt that the photos of my lesions will be used to train the machine with the correct diagnosis. I've absolutely no idea why it failed to correctly identify my lesions but it is still in the early stages of being used in the NHS and it should save money and time whilst ensuring that patients receive timely treatment for the most urgent skin cancers.
Having had this experience I would urge anyone seeing something new on their skin to get it checked out. The lesion on my nose was not obvious but it started to bleed, initially I though it was just a scratch and being on blood thinners, I tend to bleed easily. I'm so glad I got it checked out fwiw, the nose is not easy to work on surgically as there is little flesh and no extra skin so it's turned out to be more problematic than anticipated, but at least the cancer has gone. I just need the wound to start healing!

I’ll just stick with old fashioned ways of doing things. I don’t trust this AI stuff.

You are completely right- people seem to underestimate how serious these bccs can be. I found the tiniest little mark on my mums neck.. 18 stitches she had.

I have used a couple of AI searches recently after being unable to get a decent answer on a search. Results I got were surprisingly comprehensive.

My guess is that most elderly people will be intransigent about applying themselves to learn how to safely use artificial intelligence machines.

foxie48I wasn't commenting on the quality of you photographs. I am sure they were of top quality and not AI-created - and the NHS is not likely to be faking the images by which it gets a diagnosis. The algorhythms learn more as they get feedback on their work, so the more diagnoses they do, the more accurate they become.

My point was that AI apps in general are trained by giving them a very large database of examples of the work they are to be doing, taken from what has been done and published in the past. They refer to those examples when asked to answer queries, diagnose diseases from photographs, design houses, cars, interplanetary spaceships, furniture, fashionable clothes, nutritious meals, complicated electronic circuits, etc, write articles on all kinds of subjects, and write content for the never-satisfied demand of the public for "input".

Facebook has stated that the material on which its AI bots are to be trained is the whole of whatever has been added to FB by members and posters! There was a stushie when FB posters realised that it was to be assumed that if they had mentioned anything on Facebook, they were happy for it to be used by the AI as part of what it was creating or searching or compiling in a database, without asking permission. That is, names and locations, photos including children, connections, opinions, anything. Old photos are an eyecatching illustration to a FB post, so AI uses a lot of them. Unfortunately their research for the captions they write explaining what the photos depict is flawed or non-existent. It suffers from them not being human and not understanding what they see, it is just patterns of light and shade which they have been "taught" mean certain things. For instance they describe cobbled streets very frequently, when the photo shows perfectly smooth ground - because somewhere they learnt that Victorian streets were cobbled.

The material created and posted by AI was/is added to the total Fb content - increasing the size of the "training" database. So the AI was/is being trained on the content of its own products. Since a lot of the original content was dodgy in accuracy and bias level to start with, repeating it doubles up the inaccuracy and bias and "creates" nothing.

For Facebook I also mean Meta.

With google searches you get many pages of repeater content often with one bias or promotional aim, Asking AI a specific question gets a much quicker result, of course you have to ask the correct question.

An AI model could be built with a bias but that’s no different than individual source bias that we get in the media today from so called “influencers”

But you know which influencer is pressing you to buy what items - and you know that they choose what will bring them the highest income. AI is anonymous and bears the face of neutrality.

Follow the money. Find out who owns Google, Facebook, Twitter, and all the other social media sites viewed. Then find who sells AI apps, designs the way they work, and defines the databases on which they are trained.

These online media are by far the biggest influencers on the internet, and thence the biggest influencers on the vast numbers of people who, knowingly or not, use the internet for international news and information on political trends as well as for which air fryer to buy - which shapes how they see the world and how they vote.

Been saying this for the last 5 years about AI. Be afraid, be very afraid!!

The vast majority of people have idea about what it could do and will be used.
