The Slow Decline of Google Search

While many complain about Google's increased monopoly and control over our lives, in this article, I offer a different perspective regarding Google search.

And Google is moving in many other directions business-wise: Search might have been their first, most used and most well-known product, but the future…

IoT Data Science & “DML” – match made in heaven?

DML stands for “Dynamical Machine Learning” (more in the book, “SYSTEMS Analytics for IoT Data Science”, 2017). This match is not surprising once you realize that DML & IoT are both based on the venerable Systems Theory. Let us dig deeper . . .

Consider IoT for industrial applications. A machine is instrumented with sensors, data are collected in real-time (or at intervals), communicated to the cloud where IoT Data Science…
