image transcription:
an image incorporating two famous memes. on top is the title "learning about Σ* in theory of computation."
in the centre is a close-up of Chad face – often used when talking about sigma males – cropped in a five-pointed star shape.
below are two soyjaks pointing towards the aforementioned Chad face. those soyjaks are labeled "me" and "my brain".
Can images work as formal Languages?
A tree can be seen as a formal language. Look into L-systems.
If you generalize what a symbol is (the rgb value of a pixel) you can write a grammar that ends producing a list of pixels. You can then place it in a 2d matrix and you have an image.
I guess a better approach would be wave function colapse, but seems to me like it could be formally described as a grammar (CS or CF, dunno, would have to look into it)
what'd a symbol be? a pixel?
aside from this, they say a picture is worth a 1000 words. so maybe a big language.
