Query: Multimodal Sentiment Analysis using Hierarchical Fusion with Context
  Modeling   Multimodal sentiment analysis is a very actively growing field of research. A
promising area of opportunity in this field is to improve the multimodal fusion
mechanism. We present a novel feature fusion strategy that proceeds in a
hierarchical fashion, first fusing the modalities two in two and only then
fusing all three modalities. On multimodal sentiment analysis of individual
utterances, our strategy outperforms conventional concatenation of features by
1%, which amounts to 5% reduction in error rate. On utterance-level multimodal
sentiment analysis of multi-utterance video clips, for which current
state-of-the-art techniques incorporate contextual information from other
utterances of the same clip, our hierarchical fusion gives up to 2.4% (almost
10% error rate reduction) over currently used concatenation. The implementation
of our method is publicly available in the form of open-source code.
