An Approach for Learner Categorization Based on Emotions in Intelligent Adaptive E-Learning Environment

Abstract

The pandemic across the globe has constrained the change from a conventional face to face to e-learning platforms. The most challenging task during online learning is to be aware and support the emotional side of students. In existing environments, the emotion of the listener consideration is lagging. This can be provided by capturing the emotions of the listener through facial expressions. In general, the most common facial expressions are happy, sad, anger, fear, disgust, neutral and surprise. This knowledge can be used to classify different listeners. Hence in this article, we proposed a novel approach to identify an emotion based learner category in the development of Intelligent Adaptive E-Learning Environment by using Convolution Neural Network. The major work is composed of emotion detection model and learner categorization. The emotion detection model is trained by using a standard FER2013 dataset and it is extended with live streams of learners. The results of emotion detection model are extended to categorize the learners by fusing emotions and comprehend as Active, Evaluative, Passive and Non-Listener. The proposed model is trained using 100 epochs and achieved an accuracy of 94.44% in the training phase. This knowledge helps to interpret learner's participation in e-learning environment.
