The Sphering Transform for Detecting Distribution Drift
I have a new blog post up on the Win Vector blog: Detecting Data Differences Using the Sphering Transform.
![Distributions of sphered norms for two data sets with different distributions](/img/new_raw_comp_xformed-s2pbz_kSJE-400.png)
In this post, I discuss how to convert the problem of detecting changes in multivariate distributions to the simpler problem of detecting changes in univariate distributions. Please check it out.
