Then a comparison to a maximum entropy (MaxEnt) proposed in BIBREF23 type of discriminative model and finally a deep neural network (DNN) architecture proposed in BIBREF24 as reported also in BIBREF22 is presented.

 
 Question: What state-of-the-art models are compared against?
a deep neural network (DNN) architecture proposed in BIBREF24  maximum entropy (MaxEnt) proposed in BIBREF23 type of discriminative model
