Combined with lexicon-based features and transfer learning, our model achieves stateof-the-art performance, outperforming the previous best system by 4.4% Pearson correlation on the WASSA'17 EmoInt shared task dataset.
note that the pairwise correlations (heuristic 2) is only a guiding principle -the multi-task model discovers the optimal branching or sharing of layers based on the performance across a lot of variations.
