Title is misleading. “Everywhere we tried” does not include actually beating the performance (or getting particularly close to) sota transformers of the same size. That said, these models were trained for less time than the sota models so there is promise.

This is the reddit title almost verbatim. If you have a problem with that, you better leave a comment in that thread.

Still chewing but my takeaways thus far: SSM models strengths are with continuous data like audio and video, they struggle with discrete data like text/ DNA. This newest architecture uses selective attention to try to address the weaknesses around discrete data with some loss in performance in continuous tasks, empirically shown here with audio. The empirical exploration was limited to smaller size models, the perfor…

Yes, that's right. And I used the original title (though it was way longer).

Question for anyone reading the paper; what exactly is the notation in these two stages below supposed to mean?

    𝑦(𝑡) = Ch(𝑡) (1b) 𝑦𝑡 = Ch𝑡 (2b)
This is from the section describing state space models. The paragraphs before seem to describe e.g. 𝑦(𝑡) as being presumably the real value element in function/sequence 𝑦 evaluated at time 𝑡. However, it then randomly adds the 𝑦𝑡 (note the 𝑡 is supposed to be subscript) notation for what looks to be a similar equivalence and I’m not sure how thats supposed to differ in meaning from 𝑦(𝑡). Am I dumb?

That part was accurately in scare quotes.

Who are you and why should we take your questions so seriously?

y(t) is likely continuous and y_t , the subscript form, is likely the discrete version.

For example it is common in digital devices to sample something continuous(analog) every unit of time and use whatever value was captured at that moment for whatever the goal is, ideally if the something is sampled frequently enough you can even recreate the continuous version from the values.

Out of curiosity, does anyone feel as though there's any benefit to linking to reddit when we can link to whatever the reddit post actually is? I for one do not click the link and read discussion on reddit - if I wanted that sort of discussion, I would browse there, not HN.

I am with you, I don't see the point of linking to the reddit post in a situation like this.
