We conduct comprehensive experiments to evaluate the performance of VVD (section 4) on different end classification tasks.
we compare against an array of strong baseline selection algorithms, including the frequency-based algorithm (Luong et al., 2015), TF-IDF algorithm (Ramos et al., 2003), and structure lasso algorithm (Friedman et al., 2010), and demonstrate that it can consistently outperform these competing algorithms by a remarkable margin.
