A genetic algorithm (GA) is a heuristic optimization technique. The method tries to mimic natural selection and evolution by starting with a population of random candidates. Candidates are evaluated for "fitness" by plugging them into the objective function. The characteristics of the better candidates are combined to create a new
In this Q&A with MIT/SMR Connections, Iain Brown, SAS’s head of data science for the United Kingdom and Ireland, discusses some key risks, ethical issues, and platform questions that organizations should consider before adopting AI and takes a quick look at current and emerging AI trends. Q: In your view,
Every year, the SAS Championship brings a week of sports, leadership and literacy activities to the Raleigh area. Take a minute to enjoy this photo album from the week, and visit the SAS Championship online or on Twitter to learn more about the tournament, the winners and the fundraisers.
If you’ve switched on the news recently, you’ll have noticed how the words “supply chain” have now become part of Britain’s everyday vocabulary. From fuel shortages at petrol stations to the terrifying prospect of a Christmas turkey shortage, we’ve suddenly become aware of how precarious our society is, and how
The social and economic impact of COVID-19 has dramatically affected supply chains and demand planning across all industries. Then there’s the Amazon effect, which has led to sky-high consumer expectations of the ordering and delivery process. Demand planners for retailers and consumer goods companies have quickly realized they have no
SAS' Bahar Biller, an operations researcher, details how to develop a supply chain digital twin.
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
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
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
"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
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,
Leonid Batkhan introduces multipurpose TRIMS function that removes any leading, trailing or both leading and trailing characters from SAS strings.
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,
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.
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
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
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
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
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 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
“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
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.
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
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
SAS' Udo Sglavo and Jan Chvosta discuss the power of a regression framework and choosing the correct regression model.
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
Just because you are using CAS actions doesn't mean you can forget about the powerful SAS DATA step. The dataStep.runCode CAS action is here! Welcome back to my SAS Users blog series CAS Action! - a series on fundamentals. I've broken the series into logical, consumable parts. If you'd like
Overlapping social issues and additional uncertainties – not to mention a global pandemic - have led to a massive spike in people seeking mental health support. Much of that extra demand has been absorbed virtually. Canada’s Centre for Addiction and Mental Health, for example, has seen its monthly demand for
SCUBA diving is one of those activities that should be on your bucket list - everyone should experience it at least once! But where should you go diving? ... Coral reefs are always popular - and they are typically in shallow water, making it an 'easy' dive. But, being in
