Abstract: We present an extensive study on the performance of data agglomeration and decision-level fusion for robust cross-corpus emotion recognition.We compare joint training with multiple databases and late fusion of classifiers trained on single databases, employing six frequently used corpora of natural or elicited emotion, namely ABC, AVIC, DES, eNTERFACE, SAL, VAM, and three classifiers i. e. SVM, Random Forests, Naïve Bayes to best cover for singular effects.On average over classifier and database, data agglomeration and majority voting deliver relative improvements of unweighted accuracy by 9.0 % and 4.8 %, respectively, over single-database cross-corpus classification of arousal, while majority voting performs best for valence recognition.
