Mike since we have diverted from the topic of predicting accumulated cyclonic energy as a proxy for the number of storms to hit Florida, I have one for yas.

This map isn’t a Kalman filter, but it uses matrix techniques in a way vaguely analogous to that.  AncestryDNA is one of those outfits where you spit in a test tube, send it, they give you a list of relatives and a map indicating where they are from.  Several years ago there was a lotta guesswork but over time, they have accumulated more and more data from areas where the people can verify with very accurate records that all of their ancestors, every one of them, have been from right there and only right there tracing all the way back as far as these 60 dollar kits can see, which is about… around mid 1600s or so.

They revise these maps about every quarter, and as they do, their estimates get more and more accurate.  I know this because I did traditional genealogy starting in 1989, so I already knew where some of the ancestors were from.  AncestryDNA eventually figured it out and they were right.  With the accumulated data on AncestryDNA (over 26 million proles) they can now give you a pretty good idea of where your DNA came from and can even offer a surprise or two, such as… see below bottom of the map.  

That down there at the bottom is real, we traced it, learned the whole story.  It isn’t pretty, but I am glad I know it.  If there is anything in your head that you could unknow given that option, would you choose to unknow it?  Anything you have seen you would opt to unsee?  Me neither.

This all ties back into Kalman filters and learning software, for what we are seeing here is software at work and software under development, some of which I personally wrote, contributing to this.

I have mentioned this before in this forum: a software package I developed which helps proles in creating a biologically accurate family tree.  I am willing to use it to help anyone here who wants it.  Inquiring minds want to know.
