Crossover and mutation: An introduction to two operations in genetic algorithms
This article uses an example to introduce to genetic algorithms (GAs) for optimization. It discusses two operators (mutation and crossover) that are important in implementing a genetic algorithm. It discusses choices that you must make when you implement these operations. Some programmers love using genetic algorithms. Genetic algorithms are heuristic
Captain Kirk travels into space!
Recently, the news has been all abuzz about William Shatner traveling into space. This was a cool event because he's the oldest person who has traveled into space (at 90 years old) ... and he was also the iconic Captain Kirk from the original Star Trek television series. This got
Walking the tightrope in insurance
By Adam Goldsmith, Insurance Specialist, SAS UK & Ireland Insurers have the near-impossible task of keeping customers satisfied with the service they're given whilst ensuring costs are controlled to ensure profitability. At the point a customer makes a claim, it is at a point of high stress and emotion, but
Dummy's Guide to Responsible Artificial Intelligence
"Now what? Responsible artificial intelligence (AI)? You're probably going to tell me that this is going to interfere with how I go about AI." Yes, I am. There's a whole list of nations coming up with strategies on AI. Check out this world map where each colored country is having a
Growing innovation in analytics from the roots up
More than four decades ago, SAS developed a breakthrough system that helped farmers and researchers better understand and analyze crop yields and livestock production. It was pioneering work that laid a foundation for the emerging field of advanced analytics. While SAS has continued to grow and serve many other industries,
Introducing TRIMS function to remove any leading and/or trailing characters from SAS strings
Leonid Batkhan introduces multipurpose TRIMS function that removes any leading, trailing or both leading and trailing characters from SAS strings.
How SAS is saving the sweet potato
Have you ever thought of a sweet potato as ugly? These tuberous, root vegetables are a holiday staple, but the sweet potato industry prefers a certain size, shape and weight for them to make it to your grocery store. Many farmers even leave the potatoes deemed “ugly” in the fields,
Who else wants to know the mystery behind GANs?
Generative adversarial networks (GANs) are one of the newer machine learning algorithms that data scientists are tapping into. When I first heard it, I wondered how can networks be adversarial? I envisioned networks with swords drawn going at it. Close… but I can assure you that no networks were harmed in the making of this article.
Encrypting Data Using SAS
There are many reasons why you might want to encrypt data. I use a SAS program to encrypt a list of logon names and passwords. Before we get started describing how to encrypt data, let's discuss some basic concepts concerning encrypting and decrypting data. All computer data is stored as
Food quality counts
A calorie is not a calorie and the advice to simply burn more calories than you take in just doesn’t work. While being aware of calories and other macronutrient numbers is important, there is more to the puzzle. Focusing on the quality of food, not just the quantity, is key
Penalties versus constraints in optimization problems
Sometimes we can learn as much from our mistakes as we do from our successes. Recently, I needed to solve an optimization problem for which the solution vector was a binary vector subject to a constraint. I was in a hurry. Without thinking much about what I was doing, I
Can moving analytics to the cloud really be that straight forward for the UK government?
Rajeeve Narula Cloud adoption is perhaps one of the most common themes I hear in my customer interactions these days. There is a clear mandate within the UK government’s Cloud First policy for UK government and the wider public sector organisations to fully evaluate potential for the public cloud rather
Accelerate the UK forward with digital transformation across government #BuildBackBetter
Caroline Payne, Head of Customer Advisory, SAS UK Public Sector Team Digital innovation across governments around the world has accelerated in the last 18 months as leaders turn to data and technology to deliver rapid responses to the pandemic. Public organisations have had to move quickly, whilst being acutely aware
The Graph Guy is retiring!
The rumors are true - The Graph Guy is retiring! I've been working at SAS for about 30 years, and had lots of fun stretching the limits of SAS' graphing & mapping software over the years. But I've decided to retire while I'm still young enough to pursue a lot
Stop selling, start serving
“No one wants to be sold to, not even the most eager buyer in the world,” says Farnoosh Brock, a corporate trainer, speaker and writer. Brock is also an engineer and author of the book, The Serving Mindset: Stop Selling and Grow Your Business. She is a proponent of selling
Your guide for analyzing real time data with streaming analytics from SAS® Viya® on Azure
This article was co-written by Jane Howell, IoT Product Marketing Leader at SAS. Check out her blog profile for more information. As artificial intelligence comes of age and data continues to disrupt traditional industry boundaries, the need for real-time analytics is escalating as organizations fight to keep their competitive edge.
Curious Colleagues: Federica and Matteo
The process of assessing the health of a donor kidney requires the expertise of a Histopathologist, and can be a long process. “Many people are waiting for a kidney transplant, and in the meantime, they have to be on dialysis. It’s not a great quality of life,” Federica explained. As the
3 ways data and analytics can improve outcomes for the construction industry
Construction is the second largest industry in the world with a market value of $12.5 trillion, accounting for 13% of the world’s GDP. Financial services are the only industry ahead of construction, with a market value of $22.5 trillion. There are many differences between the two industries, but the most
Art or science? Choosing the right regression model
SAS' Udo Sglavo and Jan Chvosta discuss the power of a regression framework and choosing the correct regression model.
The knapsack problem: Binary integer programming in SAS/IML
Many optimization problems in statistics and machine learning involve continuous parameters. For example, maximum likelihood estimation involves optimizing a log-likelihood function over a continuous domain, possibly with constraints. Recently, however, I had to solve an optimization problem for which the solution vector was a 0/1 binary variable. To solve the

Does 5 Minutes of Movement Make a Difference?
As a fitness and wellness trainer I’m often asked “does taking the stairs really make that much of a difference?” Or “does parking further away in a parking lot count [toward improving health]?” The results are in and, yes, adding more movement into your day really does lead to a
Logical negation of vectors
In a matrix-vector language such as SAS/IML, it is useful to always remember that the fundamental objects are matrices and that all operations are designed to work on matrices. (And vectors, which are matrices that have only one row or one column.) By using matrix operations, you can often eliminate
