Variation of information can be normalized in different ways based on the properties of the application.
I added a symbol argument to specify this normalization to the
varinfo
function and set the default to the previous behavior. I also put the computation ofI, H1, H2
into a functioninformation
so that it could be reused in the future. This is a nonbreaking change.If there is a better way to do it, let me know and I can change the pull request. I think this is the least disruptive change possible. I added tests and documentation to match what was there.
