There has been further work where the responses are further ranked using a deep learning based model (Yan et al., 2016a,b;Qiu et al., 2017).
table 4 compares our model with other recent generative models (Serban et al., 2017a) -LStM (Shang et al., 2015), HRED ) & VHRED (Serban et al., 2017b).We do not compare our model with Multi-Resolution RNN (MRNN) (Serban et al., 2017a), as MRNN explicitly utilizes the activities and entities during the generation process.
