Alittle over four years ago, I was collaborating on a project with a colleague who happened to be working on his Ph.D. in artificial intelligence. Our client was in the online education space and looking to build a program that could examine a student’s history of learning and recommend what they should study next.
The request was straightforward. The challenge was the data the client wanted to collect was in an array of formats: There was information from their online system, but also papers and exams, all of which were graded differently. While one might have been marked with a percentage or grade, another could have two check marks or a smiley face.
