Visualizing new ways to protect sharks with data and analytics
Where do hammerhead sharks go at night? And perhaps more importantly, why? That's what Research Scientist and Professor Alex Hearn of the Galapagos Science Center hoped that a team of SAS analytics volunteers would be able to answer by analyzing data he's collected over nearly two decades. The project is
Trustworthy AI: 3 reasons we need it now
Who is responsible for ensuring that new AI technologies are fair and ethical? Does that responsibility land on AI developers? On innovators? On CEOs? Or is the responsibility more widespread? At SAS, we believe that it is everyone’s duty to innovate responsibly with AI. We believe that adhering to trustworthy
Overlay a curve on a histogram in SAS
In a previous article, I showed how to overlay a density estimate on a histogram by using the Graph Template Language (GTL). However, a SAS programmer asked how to overlay a curve on a histogram when the curve is not a density estimate. In this case, the vertical axis for
Reinforcement Learning in Minesweeper using SAS and OpenAI
Hi! I’m Daniel, a technical intern at SAS and a student at North Carolina State University.
