Summary for AVEC 2018: Bipolar Disorder and Cross-Cultural Affect Recognition.

The eighth Audio-Visual Emotion Challenge and workshop AVEC 2018 was held in conjunction with ACM Multimedia'18. This year, the AVEC series addressed major novelties with three distinct sub-challenges: bipolar disorder classification, cross-cultural dimensional emotion recognition, and emotional label generation from individual ratings. The Bipolar Disorder Sub-challenge was based on a novel dataset of structured interviews of patients suffering from bipolar disorder (BD corpus), the Cross-cultural Emotion Sub-challenge relied on an extension of the SEWA dataset, which includes human-human interactions recorded 'in-the-wild' for the German and the Hungarian cultures, and the Gold-standard Emotion Sub-challenge was based on the RECOLA dataset, which was previously used in the AVEC series for emotion recognition. In this summary, we mainly describe participation and conditions of the AVEC Challenge.
