Predicting meeting extracts in group discussions using multimodal convolutional neural networks
2017
This study proposes the use of multimodal fusion models employing Convolutional Neural Networks (CNNs) to extract meeting minutes from group discussion corpus. First, unimodal models are created using raw behavioral data such as speech, head motion, and face tracking. These models are then integrated into a fusion model that works as a classifier. The main advantage of this work is that the proposed models were trained without any hand-crafted features, and they outperformed a baseline model that was trained using hand-crafted features. It was also found that multimodal fusion is useful in applying the CNN approach to model multimodal multiparty interaction.
