question:
This work reframes paragraph vectors from a generative point of view and in so doing, motivates the existing method of inferring paragraph vectors as well as applying a L2 regularizer on the paragraph embeddings. The work also motivates joint learning of a classifier on the paragraph vectors to perform text classification.  The paper has numerous citation issues both in formatting within the text and the formatting of the bibliography, e.g. on some occasions including first names, on others not. I suggest the authors use a software package like BibTex to have a more consistent bibliography. There seems to be little novelty in this work.   The authors claim that there is no proposed method for inferring unseen documents for paragraph vectors. This is untrue. In the original paragraph vector paper, the authors show that to get a new vector, the rest of the model parameters are held fixed and gradient descent is performed on the new paragraph vector. This means the original dataset is not needed when inferring a paragraph vector for new text. This work seems to be essentially doing the same thing when finding the MAP estimate for a new vector. Thus the only contribution from the generative paragraph vector framing is the regularization on the embedding matrix.  The supervised generative paragraph vector amounts to jointly training a linear classifier on the paragraph vectors, while inference for the paragraph vector is unchanged. For the n-gram based approach, the authors should cite Li et al., 2015.  In the experiments, table 1 and 2 are badly formatted with .0 being truncated. The authors also do not state the size of the paragraph vector. Finally the SGPV results are actually worse than that reported in the original paragraph vector paper where SST-1 got 48.7 and SST-2 got 86.3.

question:
El trabajo pretende ofrecer una visión del uso de herramientas EVA en los diferentes entornos de asignaturas de enseñanza superior (presenciales, no presenciales y semipresenciales). La idea del paper es clara pero me cuesta trabajo encontrar la justificación de investigación del mismo. Los resultados que se obtienen son bastante segados y la propuesta no está definida como un experimento claro. Creo que hubiese sido interesante un mayor rigor a la hora de plantearlo. Hay además algunos aspectos, como por ejemplo, el hecho de la lista de evas seleccionadas que no se justifica, ¿de dónde se ha obtenido esa lista? ¿es cerrada?.  Por todo ello, abogo por no aceptar este trabajo.
