Furthermore, the mode baseline yields results that are good on the AD dataset (0.554, vs. 0.634 in <cite>(Herbelot and Vecchi, 2015)</cite> vs. 0.572 in our PLSR + word2vec implementation), and significantly better than all other models on the QMR dataset (0.522, vs. 0.346 in <cite>(Herbelot and Vecchi, 2015)</cite> , i.e. +51% improvement).
