Inside the LLM: Visualizing the Embeddings Layer of Mistral-7B and Gemma-2B 

this is the github repo: github.com/chrishayuk/embeddings

Excellent explanation. Thanks for making these examples.

Its an great video to understand the internals via the visualization. Thanks Chris.

Damn, thank you RU-vid for recommending this channel. @chrishayuk is a gun. Thanks Chris

This came to the absolute right time! Thank you very much! I was just trying to understand this. Now I know how it works ❤

Fantastic video ! I am wondering: I think it would also be very interesting to also be able have a visualization of not only the static embeddings you already did, but also a visualization of the so-called contextualized embeddings in a later layer of the model! These are the embeddings that are exposed to the attention mechanism. That why they are also called dynamic embeddings. It adds another layer of abstraction, but are better embeddings because they are able to distinguish between homonyms: words that are the same but have completely other meanings if used in another context. A good example is the word “bank”, that has several different meanings when used in another context (for example financial institution or river bank and several other meanings! ). As a consequence the word “bank” will be represented by several different vectors in embedding space, depending on the context it is used in! This technique is called Word Sense Disambiguation (WSD). Would it be possible to visualize that too? I am curious….

Great insight, thanks for posting this. It would be interesting to show how a fine-tuned model differs in similarities and "vocabulary". I'm also curious on the effects of quantisation, i.e. Q4, Q6, Q8, fp16 etc. on the internal "workings" of the LLM. Thanks again.

Thanks the visualization really helped me.

Thank you! Great video!

Thank you so much! Thank you youtube algorithm for showing such a great video!

I was playing a bit with finetuning to force an output schema for some 7B Models, but lately I discovered schema grammar, which is a way to dynamically play with the EOS tokens, by limiting them to a specific set of tokens, to generate the output you want, This is very stable and way efficient for many cases that we may think it requires finetuning, For me it felt like a new dimension to get the model intentions inline, I loved the unique and efficient way you create your videos, So I wanted to ask you if possible to create a video for us about this, I feel it's very important

This helps thanks!

Good! Where can I find your programs?
