Eu sou Professor de Data Science já há alguns anos, e não é incomum, entre alunos e colegas termos ricas conversas e debates sobre o tema Inteligência Artificial e Machine Learning. Me lembro de uma aula onde os alunos colocaram questões tão interessantes que as respostas direcionaram aquela aula e
This blog post is mostly just a bunch of fun maps ... maps that are labeled (or mislabeled) in various ways, using fun/interesting data. I focus on the 'fun' part, but if you're not careful you might also learn a little about the various ways to add labels to maps
Rijkswaterstaat (RWS) is the Netherlands main agency for design, construction, management and maintenance for waterways and infrastructure. Their mission is to promote safety, mobility and quality of life in the Netherlands. They are the masterminds behind some of the most prestigious water projects in the world. In a recent panel
Ao implantar projetos de inteligência analítica os governos enfrentam desafios não vistos no setor privado. Mas se os superarmos, a recompensa será ainda maior. Meu primeiro projeto de Ciência de Dados foi ainda durante minha graduação em Estatística. Embora não tivesse esse nome à época, o objetivo e os meios
Have you ever submitted a stored process, and instead of the expected output, you saw errors or no output at all? Depending on how you submit the stored process, various logs are available to assist you with debugging. This article provides guidance for understanding which situations call for which logs, where to find each log, and what you should look for in each log.
These days, many countries are moving away from coal, and towards natural gas, hydro, wind, and solar as ways to meet their electricity needs. I had heard that some countries still use a lot of coal (especially those countries with large coal deposits), and I was curious which countries use
I'm not sure when it started, but I've had this lifelong situation that began small, I'm sure, and then grew! While I've encouraged it to become a friend, some days it is not. You may ask who or what this friend is. It's a little thing called perfectionism. It can
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
