Yes and no at the same time, depending on what you intend to get from asking. I don't know what you were doing with this project, obviously, so I don't speak to that, but science (well, stats in general, but science needs stats) has a huge dependency on being sure the question was the correct one and not just rhyming.<p>Reading hand-written digits was the 'hello world' of AI well before LLMs came along. I know, because I did it well before LLMs came along.<p>Obviously a simple model itself can't know if it's right or wrong, as per one of Wittgenstein's quote:<p><pre><code> If there were a verb meaning 'to believe falsely', it would not have any significant first person, present indicative.
</code></pre>
That said, IMO not (as Wittgenstein seemed to have been claiming) <i>impossible</i>, as at the very least human brains are not single monolithic slabs of logic: <a href="https://www.lesswrong.com/posts/CFbStXa6Azbh3z9gq/wittgenstein-was-wrong" rel="nofollow">https://www.lesswrong.com/posts/CFbStXa6Azbh3z9gq/wittgenste...</a><p>In the case of software, whatever system surrounds this unit of machine classification (be it scripts or more ML) can know how accurately this unit classifies things in certain conditions. My own MNIST-hello-world example, split the test set and training set, the test set tells you (roughly!) how good the training was: while this still won't tell you if any given answer is wrong, it will tell you how many of those 40 million is probably wrong.<p>Humans and complex AI can, in principle, know their own uncertainty, e.g. I currently estimate my knowledge of physics to be around the level of a first year undergraduate course student, because I have looked at what gets studied in the first year and some past paers and most of it is not surprising (just don't ask me which one is a kaon and which one is a pion).<p>Unfortunately "capable" doesn't mean "good", and indeed humans are also pretty bad at this, the general example is Dunning Kruger, and my personal experience of that from the inside is that I've spent the last 7.5 years living in Germany, and at all points I've been sure (with evidence, even!) that my German is around B1 level, and yet it has also been the case that with each passing year my grasp of the language has improved, so what I'm <i>really</i> sure of is that I was wrong 7 years ago, but I don't know if I still am or not, and will only find out at the end of next month when I get the results of an exam I have yet to sit.
