Huh? A common representation of the Polya urn which results in a Dirichlet process corresponds to "novel" colors as well. If you pick a normal color you put it back with another ball of that color, but if you pick the black ball, you can pick an entire new color, hence discovery of a new thing. You can read it on Wikipedia, the source of all knowledge. :-) https://en.wikipedia.org/wiki/Dirichlet_process https://en.wikipedia.org/wiki/Dirichlet_process Original link is by the way: http://www.nature.com/srep/2014/140731/srep05890/full/srep05890.html#affil-auth http://www.nature.com/srep/2014/140731/srep05890/full/srep05...
