Multi-task Learning for Multi-modal Emotion Recognition and Sentiment Analysis
This work addresses the problem of improving accuracy in multi-modal emotion and sentiment analysis for applications like human-computer interaction, though it appears incremental as it builds on existing multi-task and attention methods.
The paper tackles multi-modal emotion recognition and sentiment analysis by proposing a deep multi-task learning framework with context-level inter-modal attention, achieving new state-of-the-art performance on the CMU-MOSEI dataset.
Related tasks often have inter-dependence on each other and perform better when solved in a joint framework. In this paper, we present a deep multi-task learning framework that jointly performs sentiment and emotion analysis both. The multi-modal inputs (i.e., text, acoustic and visual frames) of a video convey diverse and distinctive information, and usually do not have equal contribution in the decision making. We propose a context-level inter-modal attention framework for simultaneously predicting the sentiment and expressed emotions of an utterance. We evaluate our proposed approach on CMU-MOSEI dataset for multi-modal sentiment and emotion analysis. Evaluation results suggest that multi-task learning framework offers improvement over the single-task framework. The proposed approach reports new state-of-the-art performance for both sentiment analysis and emotion analysis.
