What’s new and what’s on the horizon for machine learning and analytics? We asked Kirk Borne, Principal Data Scientist and Executive Advisor at Booz Allen Hamilton, what machine learning technologies he’s watching. He focused his reply on applications, not algorithms. “When I think about what’s new and coming up, I
In my first post of this blog series, we learned how three education customers are using SAS. Today, we'll hear about the positive impact that SAS and analytics are providing for users and the education institutions. In this post, you'll hear from: Linda Sullivan, Assistant Vice President for Institutional Knowledge Management,
This post shows a variety of techniques including how to use PROC TEMPLATE and the SOURCE statement, PROC SGPLOT with multiple Y-axis tables, create comparable axes in two side-by-side graphs, create a broken axis, write and use a table template that wraps text, and find and display examples of certain statements in graph templates and fonts in style templates.
A previous article discussed the mathematical properties of the singular value decomposition (SVD) and showed how to use the SVD subroutine in SAS/IML software. This article uses the SVD to construct a low-rank approximation to an image. Applications include image compression and denoising an image. Construct a grayscale image The
In the recent article, “Price-bots can collude against consumers,” the Economist discusses the consumer effects of prices set by price-bots. The article starts with an example of gasoline pricing strategies on Martha’s Vineyard. With a small number of gas stations on the island, the price-bots can cover all competitor prices frequently
I hate hard-coding variable lists in my SAS code. I love the special variable lists SAS provides, like name:, _numeric_, etc. But back in 2011, I wrote a post titled Jedi SAS Tricks - Building a Name Suffix variable list lamenting the lack of a special variable list in base
I know that we are all anxiously following the devastating events in Houston right now. I have a very personal connection as my daughter and her family live in Houston. My daughter is a nurse and is on the emergency response team – she has been at the hospital since
Widespread flooding. Downed power lines. Broken poles. Failed transformers and breakers. Leaking pipes. Shut down refineries. The toll that a catastrophic storm takes on the energy value chain is significant. A functioning power grid, clean water and reliable fuel sources are critical for public safety and economic recovery. Even with
David Loshin explains how to set up a data catalog that will help you get more value from a data lake.
My daughter is a junior in high school, and for almost every semester she’s taken an online course as part of her studies. This semester she’s taking Spanish 3, an advanced level course where every word of instruction is spoken in Spanish. Each morning she joins the class from our
The singular value decomposition (SVD) could be called the "billion-dollar algorithm" since it provides the mathematical basis for many modern algorithms in data science, including text mining, recommender systems (think Netflix and Amazon), image processing, and classification problems. Although the SVD was mathematically discovered in the late 1800s, computers have
This example shows how to create two coordinated range attribute maps and use them in creating an animated gif of the eclipse.
This is the sixth post in my series of machine learning best practices. If you've come across the series for the first time, you can go back to the beginning or read the whole series. Aristotle was likely one of the first data scientists who studied empiricism by learning through
News flash: My favorite SAS code editor is SAS Enterprise Guide. However, my favorite general purpose text editor is Notepad++, and I often find myself using that tool for viewing SAS log files and for making small modifications to SAS programs. Judging from the popularity of this SAS Support Communities
The U.S. was really fortunate in having the recent total solar eclipse pass through so many of its states! This gave lots of people an opportunity to see it, with just a short (or moderate) drive. I think a little kid spoke for all of us when they said "Let's
