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...... hiện toàn bộ
