Each integer is represented as a vector of its prime factors, in a high-dimensionality representation such that:
[1 0 1 0 0 0 0 ...] means that the number has factors 2 and 5 (first and third primes). Then they apply a dimensionality reduction algorithm to transform these vectors into 2D vectors with real-valued coordinates. I think the result is beautiful: https://johnhw.github.io/umap_primes/index.md.html Cheers, Telmo. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
