Random note on k-Nearest Neighbor lookups on embeddings: in my experience much better results can be obtained by training SVMs instead. Not too widely known. Short example: github.com/karpathy/randomfu… Works because SVM ranking considers the unique aspects of your query w.r.t. data.

OpenAI’s ChatGPT is susceptible to prompt injection — say the magic words, “Ignore previous directions”, and it will happily divulge to you OpenAI’s proprietary prompt:

Sometimes people say, "X is technologically feasible (with deep learning), but it would require a dataset much larger than what we can collect". A more accurate take is we don't have the technology to do X given a realistically-sized dataset.

Tiny Images dataset taken down. “MIT apologizes, permanently pulls offline huge dataset that taught AI systems to use racist, misogynistic slurs” theregister.com/AMP/2020/07/…

Often we take our image datasets for granted. There’s value in actually looking at the pixels. Check out: Do We Train on Test Data? Purging CIFAR of Near-Duplicates, Björn Barz, Joachim Denzler Paper: arxiv.org/abs/1902.00423

Dear typesetting fanatics: I wrote a short Latex style guide with some tips & tricks that I find useful for making short and nice-looking papers. If you are working on ECCV papers or the like, maybe it will be useful to you, too. bit.ly/latex-style

So when asking the question, "would you rather use a model that was evaluated as 90% accurate, or a human that was evaluated as 80% accurate", the answer depends on whether your data is typical per the evaluation process. Humans are adaptable, models are not.

"Artificial intelligence" is a very bold label. In practice, I have yet to come across any technique -- at all -- that features even trace amounts of intelligence.

There is no realistic amount of data that covers "everything you can encounter" in the real world. That's what intelligence is for: to be able to handle the real world despite having only seen a very small sample of what may happen. Intelligence is extreme generalization.

Referring to prior work: ✅ Smith et al. ✅ Smith and Bigshot ✅ Smith, a student of Bigshot ❌ Bigshot ❌ Bigshot and his student Students, not advisors, do most of the hard work. Please acknowledge that when you refer to the work in your talk.

ICML review rant: The ML community is screwed if we keep insisting that scientific inquiry about known algorithms isn't "novel" (even if it leads to major new capabilities / SoTA), but that engineering yet another new, incremental algorithm that we know nothing about is great.
