Oh! Hey!

I just did something like this! I was messing around and used SVD to write a compressor. Do I dare share my feeble GitHub here lol

Sounds similar to performing PCA and keeping only the top eigenvectors

Any sufficiently good compression algorithm is inherently also a dimensionality reduction algorithm, reducing the representation down to as few dimensions as needed. This simple fact is suggestive of an origin to a number of cognitive abilities. Out of a system which evolves only for condensed representation, the ability to discern patterns in the represented things emerges for free.

Debating it - my GitHub account is basically my name… so yah… debating the subsequent loss of anonymity

Then create another one, and share that one. It's not like there is a limit of how many GitHub accounts you can have.
