Towards a General Purpose Anomaly Detection Method to Identify Cheaters in Massive Open Online Courses

Autor: Giora Alexandron, José A. Ruipérez-Valiente, David E Pritchard

We propose a general-purpose method for detecting cheating in Massive Open Online Courses (MOOCs) using an Anomaly Detection technique. Using features that are based on measures of aberrant behavior, we show that a classifier that is trained on data
