We've since changed the title. The submitted title ("94% of 36 AI systems evaluated were less accurate than a single radiologist") broke the site guidelines by editorializing. Submitters: please don't do that.

0% of the studies were better than 2 radiologists reviews - which is the current practice.

The 6% only scored better when compared to a single radiologist review. That's why we use double reviews.

What about 1 AI and 1 radiologist, then? Double the capacity for reviews.

Yes, but when disagreements occur, it's hard to make AI systems "talk" and convince one another

I'm happy someone made a comment like this.

I work an an AI company where we screen for Diabetic Retinopathy. The company is a decade old, and has validated in huge studies (over 100k patients). It's a hard problem that we have all worked very hard to solve it. At the same time, it's easy to build an AI tool that looks at an image and says healthy or unheathly (or poor quality image). So the bar is low for making something that is appears functional.

But hardly anyone makes good AI tools, so studies that look at different AIs systems see lots of the bad ones. It's always a bummer when the headlines are all dismissive of AI in general. Googling "diabetic retinopathy AI" the top result is "Artificial Intelligence Falls Short in Detecting Diabetic Eye Disease" (https://healthitanalytics.com/news/artificial-intelligence-f...), yet if you read the article it says one tool is better than humans, which to me, is the real takeaway.

I agree. I think the implied conclusion that “none of the AI know what they’re doing!” is disingenuous.

This is like the comparisons of 200 top hedge funds to index performance and concluding that hedge funds can’t beat the market. Ignoring the other conclusion: most hedge funds suck

Edit: or most hedge funds are fraudulent?

Re:Use of artificial intelligence for image analysis in brea... by eklbt on Thursday September 02, 2021 @02:29PM (#28395595)
This hedge fund example is not great because the hedge funds that beat the market(and overcome the added management fees) can't do so consistently.
Re:Use of artificial intelligence for image analysis in brea... by spywaregorilla on Friday September 03, 2021 @08:39AM (#28403344)
"Hedge funds" generally aren't supposed to beat the market. They're supposed to do different to the market. That might be, for example, generally a bit worse but hugely better if the market suffers a catastrophic loss for a simple example.

Statistically it stretches credulity to the breaking point for an outlier be an outlier year after year, whether it's in this or any other area.

I think you've misread what conclusion you're supposed to draw from this kind of assessment.

For both the hedge funds and this the conclusion isn't that the job is impossible - but that we lack the tools to predict who will do the job. You can't know which hedge fund will outperform (though some will) and we don't seem to be able to predict which AI models will perform well enough to use. Also that your odds of picking a winner "from the field" are quite bad.

It doesn't mean there's anything wrong with using a hedge fund - but there's a level of risk that one shouldn't ignore.

Like, my conclusion from this is that I would not accept a pure AI solution (because most of them are bad), but I would be interested in AI assistance. For many people, the promise is in replacing not supplementing doctors and this is the same as failure.

> the conclusion isn't that the job is impossible

Oh no, that could be the conclusion. Ever study quantum physics? Lots of people have tried to come up with some kind of model with inner "hidden" variables that tries to make HEP physics into a completely deterministic, almost classical, theory. By your logic, if we just trained and AI with enough subatomic interactions, it would eventually be able to predict with 100% accuracy the results of a quantum process.

That's utter bunk.

Markets are the same way: people think there must be some rules that can be worked out to make them 100% predictable, when in reality there is an element randomness that makes cryptographers jealous. It will never be possible to predict the next number in a random process. If you flip a coin 99 times and get 99 heads, you still can't predict what the 100th toss will be (and before someone "well ackshually"s with something about an unfair coin: don't)

> Oh no, that could be the conclusion.

I mean, the job certainly could be impossible, but those studies don't prove it. As it relates to the discussion at hand we know that we can do better at evaluating mammography because humans do it.

Maybe I am not understanding what you are saying?

Those "hedge funds can't beat index funds or the market" are marketing/PR messaging for index ETFs. Many, if not most, hedge funds are not trying to "beat the market". For some hedge funds, if they did beat the market, then they would be sued by investors for taking far too much risk. Investing has more goals than "make me the most money possible" but most naive investors don't understand this. That said, retail investors don't invest with hedge funds anyway, so most hedge funds don't really care about such misleading messaging.

"all AI systems were less accurate than consensus of two radiologists"

So 2 of the 36 were better than one radiologist, none were better than two radiologists collaborating.

The article is simplified (a retrospective metastudy) and might not be indicative of what real-life performance. Even reader studies (which would be more rigorous) skip so much that would be crucial to actual deployment (integration into the clinical workflow being one such critical factor).
Re:Use of artificial intelligence for image analysis in brea... by ChemSpider on Thursday September 02, 2021 @02:27PM (#28395567)
Exactly. PLUS: I am sure the radiologists used for this paper paid extra attention to their diagnosis, because they knew it was a competition and colleagues are watching.

I am sure the average radiologist, tired and bored at 8am in the morning, is much worse.

Re:Use of artificial intelligence for image analysis in brea... by mandevil on Thursday September 02, 2021 @03:18PM (#28396168)
This is why the standard practice today for detecting cancer is to use two radiologists to look at every image- to account for that sort of variability. And you can see that a small number of AI's were better than a single doctor, because of that human variability and frailty. None of them were better than two, however, because that variability can be adjusted for, and computers can't. Maybe they will, eventually, but I'm much less optimistic than I was <mumble mumble> years ago when I was 23 and working on vehicle autonomy.

Re:Use of artificial intelligence for image analysis in brea... by 256lie on Thursday September 02, 2021 @05:24PM (#28397554)
Even the average radiologist is high variable, not to mention inter-reader variability.
Re:Use of artificial intelligence for image analysis in brea... by jeffbee on Thursday September 02, 2021 @02:37PM (#28395698)
Under-rated comment here. The question is not whether some AI beats experts, even though the conclusion of this paper is clearly that the state-of-the-art AI does in fact beat them, but whether they are going to beat the radiologist at the free clinic in some poorly-served place.

Imagine like "94% of all attempts at heavier-than-air flight crash on first attempt". Sure... kinda misses the point.

Are you claiming that they found two AI systems that beat a skilled radiologist consistently? Because if they had, that would be the headline. People aren't stupid.

Re:Use of artificial intelligence for image analysis in brea... by pvarangot on Thursday September 02, 2021 @02:39PM (#28395728)
I never had anything serious, just sebaceous cysts and fascia inflammation. On both of those two radiologists worked on them, and everyone was pretty sure it was not cancerous or anything. I think two radiologists are standard for most things where they may recommend a biopsy.

I asked about AI and they couldn't use the one they had on the cyst because it was not trained for ankles.

Re:Use of artificial intelligence for image analysis in brea... by cratermoon on Thursday September 02, 2021 @02:34PM (#28395650)
That just means the scans were easy to interpret and/or the consequences of error were not mortal. While that's most scans, the ones where we care about the most accurate results are the ones the AI is worst.

selecting survivors of comparative study without understanding where the performances come from gives you no guarantee of future performances - which is more or less the issue with all these complex multivariate regressions that journalist, startups and venture capitalists insist calling AIs.

The guidelines say you should use the title as-is, but my attempt might put the focus on the "and 100% were worse than 2 radiologists" part, to mitigate exactly the problem of "well let's use the 6% that actually work" comments that exist without the context.
Re:Use of artificial intelligence for image analysis in brea... by OJFord on Thursday September 02, 2021 @03:59PM (#28396644)
Not GP, but I'd prefer '34' over '94%'. (Especially since the latter was parenthesised - I'd remove the parenthetical before anything else.)

(Or just 94%, and then have people say 'but N= only 36!'.)

Percentages for small numbers, in particular below 100, are just annoying and often designed to mislead. (Though I'm not suggesting that here, it's standard in medicine if not other fields.)
