Abstract: Emotion detection using electroencephalogram (EEG) signals has gained widespread acceptance in consumer preference study. It has been observed that emotion classification using brain signals has great potential over rating-based quantitative analysis. In the consumer segment, the bottom of the pyramid (BoP) people have also been considered an essential consumer base. This study aims to classify consumer preferences while visualising advertisements for BoP consumers. Four types of consumer preferences (most like, like, dislike, most dislike) have been classified while visualising different advertisements. A robust long short-term memory (LSTM)-based deep neural network model has been developed for classifying consumer preferences using the EEG signal. The proposed model has achieved 94.18% classification accuracy. The proposed model has attained a significant improvement of 11.71% and 3.24% in terms of classification accuracy over other machine learning classifiers (support vector machine and random forest), respectively. This study aims to add a significant contribution to the research domain of consumer behaviour, as it provides a guideline about the consumer preferences of the BoPs after seeing the online advertisements.
