Huang and Wang (2017) demonstrated that multi-layer ResCNNs network does achieve performance improvement by adding residual identity shortcuts, which aligns with the study that deeper CNN has positive effects on noisy NLP tasks (Conneau et al., 2017).
(4) State-of-the-art DSRE Noise Filter Systems: DSGAN (Qin et al., 2018) is a model to filter out noise instances.
