Abstract: E-learning has recently taken over the conventional method of learning, i.e., classroom lectures. E-learning, being a one-way dialog, doesn’t give feedback to the teacher on how well they are doing. This area has been hardly studied where personalized and adaptive learning systems are implemented during an e-lecture. To monitor the learner’s facial expressions, e-learning experiments have been conducted on participants and their webcam videos and self-reports are gathered. This is done in the context of four CE7412 lectures. The data is then pre-processed to make it suitable for training. The TVL/1 algorithm is applied to extract the optical flows and frames for each video. The neural networks are then trained using learner’s self-reports and his needs for Feedback and Slide Improvement. In this paper, temporal segment networks (two-stream ConvNets) are implemented to predict the learner’s affective states and their needs for Feedback and Slide Improvement. Personalized learning models trained using learner’s self-reports generalize unseen data and gain capacities for prediction of Affective States, Feedback and Slide Improvement.
