Advanced analytics from SAS data scientists![Powering disruption: A DevOps journey at SAS](https://blogs.sas.com/content/subconsciousmusings/files/2022/11/nov-dickerson-dunbar-banner-702x232.jpg)
Billy Dickerson of SAS R&D chronicles three key challenges and lessons learned in SAS' journey to continuous integration (CI) and continuous delivery (CD).
![SAS® Fast-KPCA: An efficient and innovative nonlinear principal components method Principal Component 6 x Principal Component 8](https://blogs.sas.com/content/subconsciousmusings/files/2022/11/Principal-Component-6-x-Principal-Component-8-702x336.png)
SAS® Fast-KPCA implementation bypasses the limitations of exact KPCA methods. SAS® internally uses k-means to find a representative sample of a subset of points. This row reduction method has the advantage that c centroids are chosen to minimize the variation of points nearest to each centroid and maximize the variation to the other cluster centroids. In some cases, the downstream effect of using k-means on computing the SVD increases numerical stability and improves clustering, discrimination, and classification.
