🎩🤓 Behold, the blog that bravely attempts to explain the mystical Q, K, V #matrices as if they're the holy trinity of #AI. Spoiler alert: it's mostly a glorified game of 'which word matters?' because we all need another reason to overcomplicate common sense. 🙄🔍

The Q, K, V Matrices

At the core of the attention mechanism in LLMs are three matrices: Query, Key, and Value. These matrices are how transformers actually pay attention to different parts of the input. In this write-up, we will go through the construction of these matrices from the ground up.

What are your favorite programs that specialize in working with tables? My use case: building human-readable matrices for documentation and reference. Not a database.

I don't want a typical Office program (Not Excel or Word or the FOSS equivalent.)

For example, OmniOutliner or Logseq are much better for outlining than Word etc. No, I'm not going to learn Emacs Org Mode.

Markdown tables are simple but clumsy.

I've used SQLite Browser to great effect for data., but not the right tool here.

What's actually good?

This is how you know your approaching the analytic fried zone : staring at the screen making #Math pirate noises..." Arrrrrr, ya see how this works don't ya ? We'll be squeezin #Convergence from yer scrawny little Rows and Columns, yer big fat #Matrices and anything else that gets in Captains way. We're gonna hang yer #Asymptotes out to dry in the broiling sun. We're gonna scrub the decks with yer residuals and paint the cannons with yer remainders arrrrrrr"

So yes. Possibly time for a break...

Cracovians: The Twisted Twins of Matrices

Linear algebra is typically explained using matrices. But matrix theory is just one possible perspective. Below, I describe an alternative approach to linear algebra. Tadeusz Banachiewicz (1882–195…
