🎩🤓 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. 🙄🔍

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...

Furthermore, she showed that certain stabilising effects of #network #structure can only be reproduced in theoretical #matrices when the underlying distribution of interaction strengths is highly skewed - which is in apparent contradiction to what is suggested by random matrix theory....

BLOSUM (Genetics 🧬)
In bioinformatics, the BLOSUM matrix is a substitution matrix used for sequence alignment of proteins. BLOSUM matrices are used to score alignments between evolutionarily divergent protein sequences. They are based on local alignments. BLOSUM matrices were first introduced in a paper by Steven Henikoff and Jorja Henikoff. They scanned the BLOCKS database for very conserved regions of p...

Dear #microplastic community. I do not know if you heard of this survey, feel free to participate to this 🇩🇪 initiative. It is important for those analysing ⚗️ plastic within #solid #matrices.
For all Transf ∈ ℝn×n, the matrix is invertible if and only if rank(Transf) = n
The #determinant exists if and only if the transformation matrix is square.
The determinant in a linear transformation is the (signed) area of the image of the fundamental basis formed by the unit square.

Which #matrices have an inverse?
Singular matrices never have an inverse.
When we look at the determinant, the determinant is non-zero for invertible matrices in the same way that non-zero numbers have an inverse.
Non-zero determinants mean that the matrices has an inverse, and a zero determinant means that the system (of sentences, of graphs) is singular.
