Top of hacker news today, light machine learning. Figured I would try it out on some of my spare data-collected and see if it spits out something interesting.
Will post graphs once I get it going.

which is to say that my 1/0 diet metric correlates with weight loss, but so does certain step and diet values.
This is almost exactly what I’m going to be doing… but I don’t have one built-in question… I’m just gathering qualitative data… to that end, I built an app using the hillariously easy-to-use MIT App Inventor… check out my project here: http://ai2.appinventor.mit.edu/#4930020062789632
Or you can install the apk directly here: tracker.apk (1.5 MB)
I’m accepting any/all feedback!
