Contrary to our hypothesis, MWE achieves higher accuracy than Meta-Only.
(2016) represented the text using a mean word embedding (MWE) representation, we replace it with a Convolutional Neural Network (CNN) representation (Kim, 2014), which has achieved superior performance on recent text classification tasks (Dauphin et al., 2016;Wen et al., 2016;Yang et al., 2016).
