摘要： We present a constrained attribute selection method that makes use of feature assessment based on the Fisher’s separation criterion followed by variety reduction post-processing. The post-processing incorporates task-specific constrain into the feature selection process, as this is expected to facilitate the subsequent data modeling and classification stages. Here we validate the proposed method in an experimental setup oriented towards acute stress detection based on physiological signals. The experimental results support that the proposed method brings advantage, when compared to three other cases: (i) the full set of features, (ii) a subset selected based on prior knowledge, (iii) and a subset selected based solely on Fisher’s separation criterion.

[IEEE 2018 Seventh Balkan Conference on Lighting (BalkanLight) - Varna, Bulgaria (2018.9.20-2018.9.22)] 2018 Seventh Balkan Conference on Lighting (BalkanLight) - Automated Recognition of Affect and Stress evoked by Audio-Visual stimuli
摘要： In the present work, we consider the automated detection of negative emotions and high-arousal negative-valence (HANV) states, which are akin to acute stress occurring in specific context. We investigate the influence and intricacy which subjective perception of negative emotions and acute stress brings to the process of automated recognition of these states. For that purpose we experimentally evaluate the advantages of modelling based on the person-independent tags of the audio-video stimuli, and models built with the person-specific self-reported tags. Based on the self-reported tags, which are obtained with only tiny extra effort, we report a relative improvement of the HANV detection accuracy with up to 5%.
