In addition, we apply three SOTA document vectorization methods -doc2vec (Le and Mikolov, 2014), InferSent (Conneau et al., 2017), and BERT (Devlin et al., 2019) -and use the extracted vectors to train a linear regressor to predict emotion distributions.
considerable research efforts on small sample learning are emerging recently (Lake et al., 2015;Shu et al., 2018).
