Predictive analytics, a subset of BI analytics, was a hot topic at the Information Builders Summit in Kissimmee, Fla., this week. Predictive BI analytics is about detecting and interpreting patterns in business data in order to make guesses about what’s probably around the corner. Humans are pretty good at this, or we wouldn’t be here. As the amount of data that businesses collect, process and store in any given minute swells, the task of seeing the relevant patterns increasingly is the job of machine learning, artificial intelligence and data mining tools.
One thing we haven’t lost is our love of puzzles. Test your analytics IQ with four brainteasers, offered up in a session on BI analytics by researcher and BI author Wayne Eckerson of TDWI Research. (The smarties in the room were quick to solve all but one.)
