See how to sample unstructured (text) data using SAS Viya and CAS actions. This post includes complete code to cluster the text documents via k-means, and treats the cluster memberships as strata for analysis.
In the new era of online visual communication, when you have to be fast and clear, emojis are getting a strong relevance as the main language that allows us to communicate with anyone globally. Customers know it and brands too. Collecting and analyzing data on emojis give companies useful insights
In a previous article, I showed how to find the intersection (if it exists) between two line segments in the plane. There are some fun problems in probability theory that involve intersections of line segments. One is "What is the probability that two randomly chosen chords of a circle intersect?"
With a couple of big games coming up tonight and tomorrow, we teamed up with our partner SciSports to analyse the strengths of the remaining four teams. Here is an analysis of the French and Belgian teams. SciSports is a Dutch company providing data analysis and intelligence to the football industry. Their
I have lived in the Town of Cary for more than twenty years; two of my three children were born at the local WakeMed Cary Hospital. I’m a big fan of my city, or town as it prefers to be called – even though the population is over 160,000. That’s
More than 3.5 percent of the world’s population is on the move, considered international migrants. That’s more than 250 million people living in a country different than their country of birth or nationality. To put that another way, if all migrants lived in a single country, their population would be
I've said it before: spreadsheets are not databases. However, many of us use spreadsheets as if they were databases, and then we struggle when the spreadsheet layout does not support database-style rigor of predictable rows, columns, and variable types -- the basic elements we need for analytics and reporting. If
Jim Harris says the GDPR may cause seismic changes in how people think of privacy and personal data.
Many things in nature can be seen as chain reactions. When one action occurs, others follow suit. For example, atmospheric greenhouse gas levels are increasing, which leads to a warming of the oceans. As the oceans warm, weather and climate patterns across the globe are impacted because the amount of
Continuing our series on model interpretability, this post explains two methods for plotting variables that can give insight into how a model is working. Assessing a model`s accuracy usually is not enough for a data scientist who wants to know more about how a model is working. Often data scientists
Sequence models, especially recurrent neural network (RNN) and similar variants, have gained tremendous popularity over the last few years because of their unparalleled ability to handle unstructured sequential data. The reason these models are called “recurrent” is that they work with data that occurs in a sequence, such as text
This article shows how to construct a butterfly plot in SAS. A butterfly plot (also called a butterfly chart) is a comparative bar chart or histogram that displays the distribution of a variable for two subpopulations. A butterfly plot for the cholesterol readings of 5,057 patients in a medical study
When data meets geography, use cases revolve around mapping and spatial analytics. But what happens when you combine digital analytics and powerful visualization for customer location analysis? Leveraging data collection mechanisms, SAS 360 Discover captures first-party behavioral information across the entire digital customer experience with a brand’s websites and mobile
Open data is critical to research, particularly at universities. The many university students that attend SAS Global Forum bring an energy and vitality to the conference that is unmistakable. They’re everywhere…in sessions, social activities, out on the town and, of course, the academic events. This year, 150 of them graced
In a previous blog post, I discussed ways to produce statistically independent samples from a random number generator (RNG). The best way is to generate all samples from one stream. However, if your program uses two or more SAS DATA steps to simulate the data, you cannot use the same
I have good news to share about the future. Despite what you may have heard elsewhere, the future of work in a world with artificial intelligence (AI) is not all doom and gloom. And thanks to a research-backed book from Malcolm Frank, What to Do When Machines Do Everything, we
The European Union’s General Data Protection Regulation (GDPR) taking effect on 25 May 2018 pertains not only to organizations located within the EU; it applies to all companies processing and holding the personal data of data subjects residing in the European Union, regardless of the company’s location. Here are four selected SAS tools for GDPR that allow you to protect personal data in SAS reports by suppressing counts in small demographic group reports.
In the following 2012 season, NBA teams shot an average of 18.4 three-point shots per game, which had risen by four shots per game since the 2001-02 season. Just five years later, this number rose by 8.6 attempts per game, to an average of 27 attempts in 2017. But what caused this increase?
Landmark population health study involving 50,000 northern Nevadans turns to SAS to reveal hidden health insights These are exciting times in health care. Earlier this week I read that the NIH will soon open enrollment for its “All of Us” initiative. The research program aims to compile the genetic and health
When you ask Mark Yost about what he does at SAS every day, his eyes light up. Mark’s our Assistant Manager for Food Services at SAS, but he’s so much more than that. He’s a champion for diversity and a leader who empowers his team to be the same. For
A future of flying cars and Minority Report-styled predictive dashboards may still be some time away, but the possibilities of robotics and Artificial Intelligence (AI)-powered automation are a reality today. From connected cars to smart homes and offices, we see daily how big data and the Internet of Things (IoT)
What if a famous soccer team asks you to predict how many tickets for their next match will be sold to women? Seventy students from Bicocca University of Milan tried to answer this question a couple of weeks ago. They were divided into 19 groups during a hackathon that SAS
You've probably heard about the "80-20 Rule," which describes many natural and manmade phenomena. This rule is sometimes called the "Pareto Principle" because it was discovered by Vilfredo Pareto (1848–1923) who used it to describe the unequal distribution of wealth. Specifically, in his study, 80% of the wealth was held
SAS® supports the creation of deep neural network models. Examples of these models include convolutional neural networks, recurrent neural networks, feedforward neural networks and autoencoder neural networks. Let’s examine in more detail how SAS creates deep learning models using SAS® Visual Data Mining and Machine Learning. Deep learning models with

The SAS® Global Forum Technology Connection isn’t just an opportunity to show off what SAS has been working on. It’s a chance to meet the people behind SAS® technology, see the results of their relentless curiosity, and understand how the world is transformed by it. Executive Vice President, Chief Operating Officer and
A colleague and I recently discussed how to generate random permutations without encountering duplicates. Given a set of n items, there are n! permutations My colleague wants to generate k unique permutations at random from among the total of n!. Said differently, he wants to sample without replacement from the
New technologies offering new ways to solve complicated and costly problems are entering the health care sector . Artificial intelligence (AI) is one of them. To succeed with AI, you need to think in an analytical manner, to build an analytical organisation and, as a part of that, you need an analytics
SAS has never been able to sit idle and watch from the sidelines as crises ensue. Why? Because we know that good can be made possible if data is put to work. SAS Global Forum opening session spotlighted four real-life examples of how SAS is showing up and improving the
Bright lights, a packed house, loud music and high energy – these are the elements that come to life every year in the SAS Global Forum opening session. But it’s not just about the entertainment and energy. Each year, the Sunday night opening session sets the stage for conference attendees.
