It isn't limited to the medical field. This is quite common in most fields.
I understand testing knowledge and intelligence is an intractable problem, but I my main wish is that this would simply be acknowledged. That things like tests are _guidelines_ rather than _answers_. I believe that if we don't acknowledge the fuzziness of our measurements we become overconfident in them and simply perpetuate Goodhart's Law. There's an irony in that to be more accurate, you need to embrace the noise of the system. Noise being due to either limitations in measurements (i.e. not perfectly aligned. All measurements are proxies. This is "measurement uncertainty") or due to the stochastic nature of what you're testing. Rejecting the noise only makes you less accurate, not more.
- fsckboy 2y agoif something happens comprehensively across fields, it's likely to be a good idea. the idea that one guy who interviewed people "properly" could assemble a team that was better at the job across the board and disrupt that industry, and other such guys across other industries would disrupt those industries, seems a little farfetched.
- godelski 2y ago> if something happens comprehensively across fields, it's likely to be a good idea. I don't have high confidence that this is likely. I've seen a lot of bad habits happen simply because "that's how X does it." Which often misses a lot of context. Those things matter, and often matter a lot. Not to mention that information is always passed via a game of telephone [0]. This is related to "trust, but verify". If a big player is doing something it is worth looking at to see if it's a good idea for you. Same with when something is popular. But you have to be careful too. It's easy to miss context or small details that make a big difference. As an example, Google has a surplus of high quality candidates. Any arbitrary filter is helpful to them as they just need to down select. So a highly noisy process (i.e. random with a small bias) will yield good results for them. You'll even MEASURE positive results! This isn't necessarily (might be, might not be) true for anyone who isn't big tech or highly bureaucratic. (Same is true for college admissions) It's important to remember that big players don't maintain their status simply because no other can out innovate. Rather momentum is a bitch. It can make up for a lack of innovation and still out compete. [0] https://en.wikipedia.org/wiki/Telephone_game https://en.wikipedia.org/wiki/Telephone_game

If the tests asked questions to measure the latter, I suspect LLMs would fare far less impressively.
- godelski 2y agoYes, you're fairly spot on. (But I still encourage you to read all this) I refer to them as "fuzzy databases" (this is a bit more general than transformers too), because they are good at curve fitting. There's a big problem with benchmarks in that most of the models are not falsifiable in their testing. Since it is not open of what they have trained on, you cannot verify that tasks are "zero-shot"[0]. When you can, they usually don't actually look like it. Another example is looking at the HumanEval dataset[1]. Look at those problems and before searching, ask yourself if you really think they will not be on GitHub prior to May 2020. Then go search. You'll find identical solutions (with comments!) as well as similar ones (solution is accepted as long as it works). IME there's a strong correlation between performance and number of samples. You'll also see strong overfitting to things very common. That said, I wouldn't say LLMs aren't able to perform novel synthesis. Just that it is highly limited. Needing to be quite similar to the data it was trained on, but they __can__ extrapolate and generate things not in the dataset. After all, it is modeling a continuous function. But they are trained to reflect the dataset and then trained to output according to human preference (which obfuscates evaluation). Additionally, I wouldn't call LLMs useless nor impressive. Even if they're 'just' "a fuzzy database with a built in human language interface", that is still some Sci-Fi shit right there. I find that wildly impressive despite not believing it is a path to AGI. But it is easy to undervalue something when it is highly overvalued or misrepresented by others. But let's not forget how incredible of a feat of engineering this accomplishment is even if we don't consider it intelligent. (I am an ML researcher and have developed novel transformer variants) [0] A zero-shot task is one that it was not trained on AND is "out of distribution." The original introduction used an example of classification where the algorithm was trained to do classification of animals and then they looked to see if it could _cluster_ images of animals that were of distinct classes to those in the training set (e.g. train on cats and dogs. Will it recognize that bears and rabbits are different?). Certainly it can't classify them, as there was no label (but classification is discrimination). Current zero-shot tasks include things like training on LAION and then testing on ImageNet. The problem here is that LAION is text + images and that the class of images are a superset (or has significant overlap) with the classes of images in ImageNet (label + image). So the task might be a bit different, but it should not be surprising that a model trained on "Trying for Tench" paired with an image of a man holding a Tench (fish) works when you try to get it to classify a tench (first label in ImageNet). Same goes for "Goldfish Yellow Comet Goldfish For The Pond Pinterest Goldfish Fish And Comet Goldfish" and "Goldfish" (second label in ImageNet). (view subset of LAION dataset.
