  In this paper, we present our solutions for the Multimodal Sentiment Analysis
Challenge (MuSe) 2022, which includes MuSe-Humor, MuSe-Reaction and MuSe-Stress
Sub-challenges. The MuSe 2022 focuses on humor detection, emotional reactions
and multimodal emotional stress utilizing different modalities and data sets.
In our work, different kinds of multimodal features are extracted, including
acoustic, visual, text and biological features. These features are fused by
TEMMA and GRU with self-attention mechanism frameworks. In this paper, 1)
several new audio features, facial expression features and paragraph-level text
embeddings are extracted for accuracy improvement. 2) we substantially improve
the accuracy and reliability of multimodal sentiment prediction by mining and
blending the multimodal features. 3) effective data augmentation strategies are
applied in model training to alleviate the problem of sample imbalance and
prevent the model from learning biased subject characters. For the MuSe-Humor
sub-challenge, our model obtains the AUC score of 0.8932. For the MuSe-Reaction
sub-challenge, the Pearson's Correlations Coefficient of our approach on the
test set is 0.3879, which outperforms all other participants. For the
MuSe-Stress sub-challenge, our approach outperforms the baseline in both
arousal and valence on the test dataset, reaching a final combined result of
0.5151.
