MMOD-COG: A Database for Multimodal Cognitive Load Classification
This paper presents a dataset for multimodal classification of cognitive load recorded on a sample of students. The cognitive load was induced by way of performing basic arithmetic tasks, while the multimodal aspect of the dataset comes in the form of both speech and physiological responses to those tasks. The goal of the dataset was two-fold: firstly to provide an alternative to existing cognitive load focused datasets, usually based around Stroop tasks or working memory tasks ; and secondly to implement the cognitive load tasks in a way that would make the responses appropriate for both speech and physiological response analysis, ultimately making it multimodal. The paper also presents preliminary classification benchmarks, in which SVM classifiers were trained and evaluated solely on either speech or physiological signals and on combinations of the two. The multimodal nature of the classifiers may provide improvements on results on this inherently challenging machine learning problem because it provides more data about both the intra- participant and inter-participant differences in how cognitive load manifests itself in affective responses.
