In this paper, we propose an audio-visual emotion recognition system using
multi-directional regression (MDR) audio features and ridgelet transform based
face image features. MDR features capture directional derivative information in
a spectro-temporal domain of speech, and, thereby, suitable to encode different
levels of increasing or decreasing pitch and formant frequencies. For video
inputs, in... hiện toàn bộ

AbstractWhile the research area of artificial intelligence benefited from
increasingly sophisticated machine learning techniques in recent years, the
resulting systems suffer from a loss of transparency and comprehensibility,
especially for end-users. In this paper, we explore the effects of incorporating
virtual agents into explainable artificial intelligence (XAI) designs on the
perceived trust ... hiện toàn bộ
