They are literally taking all the tricks that vision ppl used on ViT re-pbublishing them. When are they going to publish something like Swin-LLM?

Good points. I think the next one will be Deformable Masked Attention

“ Different from vanilla attention, both sizes of K and V are independent of the sequence length N, making the
communication cost constant.”
This sentence is doubtful.Show the provement that the K_i and V_i are independent of the sequence length N.These tensors' size are still related to sequence length even you did the dilation.

we should have a dislike button too.. don't you think?

Is there any model avaliable ?

This is happening for quite a sometime now. Using NLP in CV and CV in NLP.
End of the day its the math.

Hey, Im reviewing deep learning papers on twitter daily in Hebrew via hashtag #https://twitter.com/hashtag/shorthebrewpapereviews?src=hashtag_click. So far I've shortly reviewed about deep learning papers. You are invited to follow and comment

This paper review can be found at: https://twitter.com/MikeE_3_14/status/1676988738377744388?s=20

They are literally taking all the tricks that vision ppl used on ViT re-pbublishing them. When are they going to publish something like Swin-LLM?

Is this so bad, as long as they cite CV papers? It's... arguably... how science ought to work?

No matter the source of their inspiration (deepmind always does this..), we want it on huggingface ASAP !

please gibe me model

Is "LongNet: Scaling Transformers to 1,000,000,000 Tokens" something like this?

@Emil-Zakirov here is an implementation you can refer https://github.com/kyegomez/LongNet

@unknownentity does is accept inputs_embeds like in huggingface ?

The official Microsoft implementation is in the TorchScale repo (no pretrained checkpoints that I know of, you have to train it yourself). https://github.com/Microsoft/TorchScale
