Feed: SAS Blogs. Author: Britta Skriver. Around the world, combating public sector fraud is a major problem. "Benefits cheats" get the most media attention, but are by no means the biggest loss. Tax fraud is also a huge issue. And some estimates suggest that procurement fraud could dwarf both in terms of both scale and complexity. Fortunately, however, even as fraud gets more imaginative and more complex, better and more effective analytics techniques, including machine learning and artificial intelligence (AI)-based algorithms, are becoming available. These are helping to save taxpayers’ money at both local and national levels in a number ... Read More

Feed: Logicworks. Author: Lindsay Syhakhom; Teachers do more than just teach. They’re also asked to be social workers, a medical triage team, psychologists, and more.

In 2018, Nikody Keating launched mytaptrack to help teachers quickly and easily track the issues of kids with special needs. Rather than manually filling ... Read More
