Stanford AI Recreates Periodic Table

Fascinating example.   Could this kind of structure be sought elsewhere?  Thinking it.

Stanford AI recreates chemistry’s periodic table of elements
In a first step toward generating an artificial intelligence program that can find new laws of nature, a Stanford team created a program that reproduced a complex human discovery – the periodic table.  By Ker Than

It took nearly a century of trial and error for human scientists to organize the periodic table of elements, arguably one of the greatest scientific achievements in chemistry, into its current form.
A new artificial intelligence (AI) program developed by Stanford physicists accomplished the same feat in just a few hours.

Called Atom2Vec, the program successfully learned to distinguish between different atoms after analyzing a list of chemical compound names from an online database. The unsupervised AI then used concepts borrowed from the field of natural language processing – in particular, the idea that the properties of words can be understood by looking at other words surrounding them – to cluster the elements according to their chemical properties  ...
