As a computer vision guy I'm sad JEPA didn't end up more effective. Makes perfect sense conceptually, would have easily transferred to video, but other self-supervised methods just seem to beat it!
turnersr · a year ago
Yeah! JEPA seems awesome. Do you mind sharing what other self-supervised methods work better than JEPA?

Pinecone stores and searches through dense vector embeddings using a proprietary ANN index. It also has live index updates and metadata filtering, which you’d expect from any database but is surprisingly hard to find or do with vector indexes.

As you said, common use cases include deduplication and image search, and especially semantic search (text).

Do you happen to know other implementations that allow for live updates and metadata filtering like Pinecone?

Hi all, author here! My submission fell of the new page after 5 minutes sometime this morning and really glad to see it get re-posted.

AMA!

Awesome work!!!! curious how you handle paragraphs and niche language like federal regulations.

What are your favorite ways to do sentence and paragraph embeddedings and is there a framework you like where you can tune to custom data? Do you find fine tuning your embedding model helpful?

> but this story has been way overblown based on what I saw in the actual code.

Could you expand on this? What code did you see, where, and doing what? Were you part of this team?

> There's nothing particularly new about mathematicians using computers to investigate and make conjectures, even if you add ML into it.

I think you're being needlessly reductive here. The article itself explicitly states that "using computers" is not what's new.

turnersr commented on Tortured phrases: A dubious writing style emerging in science   nature.com/articles/d4158... · Posted by u/DanBC

I have encountered something similar to this for a submission that I reviewed for a scientific journal. I will not list any names or give much detail past those generalities, but I pointed out that the authors were misusing a particular technical term. In my review I defined the term and explained it briefly. I asked the authors to revise their submission accordingly. The paper was not bad but the authors did not know English very well, so it was quite difficult to read. That was its main problem. However, when I received the revised submission, I noticed that the authors plagiarized my definition and explanation almost word for word (from my confidential review). I pointed this out to the editors and they said to just reject the paper with the stated reason being plagiarism, which I did. The journal ended up rejecting the article, but I discovered it a few years later in a different journal. The plagiarized section remained, but the authors swabbed out a lot my phrases for these kind of "tortured phrases".

That said, the authors did not fabricate their research (as far as I can tell). They just did not know English well, so it was easier to just copy things that you know are phrased well than to learn to write English well. As the saying goes, do not attribute to malice what can be explained by ignorance or laziness. That does not excuse it but it makes it more understandable.

I agree with the article that this is probably just the tip of the iceberg. There are likely many more lesser evils being committed with similar tools that are just much more difficult to spot. I would not have noticed my particular example if I were not a reviewer for the paper, for example. It makes me wonder how big the problem really is.

In your review, did you suggest the definition and explanation that they used? In this situation, would have an acknowledgment at the end have been enough? In my mind, it seems like you all had a conversation and the authors took up your suggestions as the reviewer.

I would love to be able to search math and scientific literature. Do you all support LaTex?
turnersr commented on Enzyme – High-performance automatic differentiation of LLVM   enzyme.mit.edu/... · Posted by u/albertzeyer
wsmoses · 5 years ago
Hi all, another author here and happy to answer any questions!

Some more relevant links for the curious

Github: https://github.com/wsmoses/Enzyme

Paper: https://proceedings.neurips.cc/paper/2020/file/9332c513ef44b...

Basically the long story short is that Enzyme has a couple of interesting contributions:

1) Low-level Automatic Differentiation (AD) IS possible and can be high performance

2) By working at LLVM we get cross-language and cross-platform AD

3) Working at the LLVM level actually can give more speedups (since it's able to be performed after optimization)

4) We made a plugin for PyTorch/TF that uses Enzyme to import foreign code into those frameworks with ease!

Hello,

Thank you for sharing and releasing usable code! Do you know if this would work for GPU based applications? Tensorflow models that are trained on a GPU, for example?

Do you know of any interesting natural ismorphism between the categories you define in your paper and the category of finite-dimensional hilbert spaces? Curious if you have thought about applications to categorical quantum mechanics.
turnersr commented on Dave’s Short Course on Complex Numbers (2013)   www2.clarku.edu/faculty/d... · Posted by u/blewboarwastake
taliesinb · 5 years ago
Is anyone aware of a resource that collects examples of what complex numbers “encode” in various settings in which they naturally appear?

For example, complex numbers in the eigendecomposition of a real-valued square matrix encode permutations among dimensions in a particular eigenspace via the roots of unity — which amount to rotations. So they’re a bookkeeping device that allows the eigendecomposition of an automorphism of a real vector space to actually work in all cases.

Do you have a reference or example of how this encoding works? Curious about this interpretation of complex numbers. Thanks for sharing!
turnersr commented on India bans PUBG, Baidu and more than 100 apps linked to China   bbc.com/news/technology-5... · Posted by u/sameer_hacker

The Chinese government mandates that every app written in China must track and trace it's users. This applies to apps running outside China but owned by Chinese companies.

1+ or Xiaomi or Huawei, they can't really do anything about it.

They have to track users to be not banned.

Do you have a reference for this? Would love to see how this is written down and enforced.
