The triangulation theorem for polygons says that every simple polygon can be triangulated. In fact, if the polygon has V vertices, you can decompose it into V-2 non-overlapping triangles. In this article, a "polygon" always means a simple polygon. Also, a "random point" means one that is drawn at random
Discovery is an important part of setting up your analysis for success – essentially it prevents you from plunging into a haystack to try to find that elusive needle, and rather, helps you organize the haystack into neater, compact organized bales that you can navigate with ease. Proper discovery can help you more efficiently find patterns in your data set.
Here in the United States, we have our general election (where we elect the president) every four years - and 2020 happens to be one of those election years. This time we seem to have a lot more people voting early. I can't tell you the reason they're voting early
Who Helps the World? Girls! Decades of research show there's one strong difference in what young men and women say they value in a future career: The opportunity to help others. And young women are far more likely to say that they want a job where they can have a positive
What does the AI enterprise of the future look like? That’s a tough question that I’ve been asked to consider, along with a distinguished panel at Valley ML AI Expo 2020. The title of the panel is, “Life, the Universe and the AI Enterprise of the Future.” Based on an initial chat with panel chair Gautam Khera, I’ve written up some possible topics we’ll be covering on the panel. Consider
When you use SAS software, you might occasionally encounter an issue with SASUSER. This post helps you debug some of the more common issues: a warning message indicates that SASUSER.TEMPLAT is not an item store or that you cannot write to SASUSER.TEMPLAT a note in the log indicates that SAS
Sherrine Eid believes there is strength in numbers. At SAS, we have access to some of the best and brightest scientists, mathematicians, econometricians, epidemiologists and biostatisticians, who are all driven by the same thing: They want to make this world a better place. "My passion is to objectively assess patterns
Depending on who you talk to, you'll get varying definitions and opinions regarding demand sensing. Anything from sensing short-range replenishment based on sales orders, to the manual blending of point-of-sales (POS) data and shipments. But a key component for retailers and CPG companies is accurately forecasting short-term consumer demand to
How can you efficiently generate N random uniform points in a triangular region of the plane? There is a very cool algorithm (which I call the reflection method) that makes the process easy. I no longer remember where I saw this algorithm, but it is different from the "weighted average"
“Technology is an industry that eats its young, it is rare to come across providers that have been around for more than a human generation.” Tony Bear, Big on Data With more than 40 years in the market, SAS is one of the rare technology providers that has been around
Two billion people worldwide experience food insecurity and 14% of food produced for humans to consume is wasted before it arrives at the wholesaler, according to the Food and Agriculture Organization of the United Nations (FAO). The FAO celebrates World Food Day on October 16, 2020. This year’s event focuses
Now that we are many months into the COVID-19 pandemic, we can start to reexamine the data and look for trends. This time, I want to explore how COVID-19 has been spreading around the US. I do this by animating a county map over time. What is animation? Are you
Over the last 30 years, manufacturing in Romania has seen huge changes from a planned economy to a market-based one. It now has a very diverse manufacturing scene, with both large and small companies, and a wide range of products from steel through to finished goods. However, few manufacturers are
Whether you’re looking for technical or business opportunities, a strong resume will help you stand out from the crowd and make a good first impression. But resume creation is an art, not a science, and starting from scratch can feel daunting. Never fear – our intern Program Manager, Kristen Garbarino, is here! She sees thousands of student resumes each year, so we asked for her take
SAS' Leonid Batkhan summarizes a lesser known but useful feature in SAS that allows you to bring Microsoft Excel functions into your SAS programs.
ModelOps is NOT a one-size-fits-all approach. It's important to identify the appropriate level of sophistication based on both the organization’s current readiness and its current and future business needs. My previous articles on Medium talked about why organizations should choose ModelOps, and how to implement ModelOps using a holistic approach
The retail sector has been in a state of change for many years now. Retailers have long been discussing the shift to online – or rather the correct balance between online and "bricks and mortar" – and how to cater to customers’ desire to use multiple channels for different parts
Being overwhelmed by the volume of news isn’t a new phenomenon. But today, our sense of being overwhelmed has increased and triggered feelings of fear, frustration and anxiety, given the ongoing developments and research tied to COVID-19. How do we sift through the volume of information facing us and truly understand whether the news we consume is factual or based on
Jicama dickory dock. Eat this root vegetable — it’s not a rock. Chop it up and see How tasty it can be, Especially when you serve it with guac. Pronounced HEE-ka-ma, this unassuming tuber might be something you stroll right by in the produce section of your grocery store without
A previous article discusses the confidence band for the mean predicted value in a regression model. The article shows a "graded confidence band plot," which I saw in Claus O. Wilke's online book, Fundamentals of Data Visualization (Section 16.3). It communicates uncertainty in the predictions. A graded band plot is
SAS is on a marketing transformation mission. One that has targeting and personalization at the forefront. One that looks at customer journeys from a true omnichannel perspective – not through each of the channels in which we're executing. We’re bringing in brand, demand and engagement with the customer at the center
This is a repost of a blog I wrote early in the pandemic. It is even more relevant now and I hope it will be encouraging and comforting to all of you exhausted parents out there. As I sit down to write this blog, I really wish I had "the
After he birdied the last two holes of the SAS Championship on Sunday, Ernie Els walked away with the trophy, besting a star-studded field to get his second win of the season. One of golfing’s greatest players with four major championships to his name, Els fired a 6-under 66 on a
Many of us are lucky to have food on the table and grocery stores stocked with the food and beverages we want or need, and this is in a large part, due to our farmers. If you didn’t grow up on a family farm or a rural area where corn
You've probably seen many graphs that are similar to the one at the right. This plot shows a regression line overlaid on a scatter plot of some data. Given a value for the independent variable (x), the regression line gives the best prediction for the mean of the response variable
Most of us know about electric vehicles (EVs), and the fact that they charge when connected to the grid. However, the technology is moving on. Instead of simply drawing from the grid, some EVs now have the capacity to feed energy to the grid from their batteries. This is known
It’s been a while and the gym is FINALLY open! Yippee! But…it’s been months since you’ve done more than body weight exercises, you’ve never tried exercising in a mask, and what’s this about making reservations? Let’s face it, gyms are looking a little different these days. As you venture out,
Images and artificial intelligence You don’t have to be a computer geek to know that artificial intelligence (AI) is having a moment in the sun just now. In recent years, we have made huge progress in the field of AI, and particularly through deep learning algorithms. These algorithms have been
How coronavirus has led banks to reassess the value and purpose of local banking services
A previous article shows how to use a recursive formula to compute exact probabilities for the Poisson-binomial distribution. The recursive formula is an O(N2) computation, where N is the number of parameters for the Poisson-binomial (PB) distribution. If you have a distribution that has hundreds (or even thousands) of parameters,
