question:
I'd like to thank the authors for their detailed response and clarifications.  This work proposes new training scheme for online sparse dictionary learning. The model assumes a non-stationary flow of the incoming data. The goal (and the challenge) is to learn a model in an online manner in a way that is capable of  adjusting to the new incoming data without forgetting how to represent previously seen data. The proposed approach deals with this problem by incorporating a mechanism for adding or deleting atoms in the dictionary. This procedure is inspired by the adult neurogenesis phenomenon in the dentate gyrus of the hippocampus.   The paper has two main innovations over the baseline approach (Mairal et al): (i) “neuronal birth” which represents an adaptive way of increasing the number of atoms in the dictionary (ii) "neuronal death", which corresponds to removing “useless” dictionary atoms.  Neural death is implemented by including an group-sparsity regularization to the dictionary atoms themselves (the group corresponds to a column of the dictionary). This promotes to shrink to zero atoms that are not very useful, keeping controlled the increase of the dictionary size.  I believe that the strong side of the paper is its connections with the adult neurogenesis phenomenon, which is, in my opinion a very nice feature. The paper is very well written and easy to follow.  On the other hand, the overall technique is not very novel. Although not exactly equivalent, similar ideas have been explored. While the neural death is implemente elegantly with a sparsity-promoting regularization term, the neural birth is performed by relying on heuristics that measure how well the dictionary can represent new incoming data. Which depending on the "level" of non-stationarity in the incoming data (or presence of outliers) could be difficult to set. Still, having adaptive dictionary size is very interesting.  The authors could also cite some references in model selection literature. In particular, some ideas such as MDL have been used for automatically selecting the dictionary size (I believe this work does not address the online setting, but still its a relevant reference to have). For instance,  Ramirez, Ignacio, and Guillermo Sapiro. "An MDL framework for sparse coding and dictionary learning." IEEE Transactions on Signal Processing 60.6 (2012): 2913-2927.

question:
- Strengths:  The authors present a novel adaptation of encoder-decoder neural MT using an approach that starts and ends with characters, but in between works with representations of morphemes and characters.   The authors release both their code as well as their final learned models for fr-en, cs-en, and en-cs. This is helpful in validating their work, as well as for others looking to replicate and extends this work.  The system reported appears to produce translation results of reasonable quality even after the first training epoch, with continued progress in future epochs.  The system appears to learn reasonable morphological tokenizations, and appears able to handle previously unseen words (even nonce words) by implicitly backing off to morphemes.  - Weaknesses:  In the paper, the authors do not explicitly state which WMT test and dev sets their results are reported on. This is problematic for readers wishing to compare the reported results to existing work (for example, the results at matrix.statmt.org). The only way this reviewer found to get this information was to look in the README of the code supplement, which indicates that the test set was newstest2015 and the dev test was newstest2013. This should have been explicitly described in the paper.  The instructions given in the software README are OK, but not great. The training and testing sections each could be enhanced with explicit examples of how to run the respective commands. The software itself should respond to a --help flag, which it currently does not.  The paper describes a 6-level architecture, but the diagram in Figure 2 appears to show fewer than 6 layers. What's going on? The caption should be more explicit, and if this figure is not showing all of the layers, then there should be a figure somewhere (even if it's in an appendix) showing all of the layers.  The results show comparison to other character-based neural systems, but do not show state-of-the-art results for other types of MT system. WMT (and matrix.statmt.org) has reported results for other systems on these datasets, and it appears that the state-of-the-art is much higher than any of the results reported in this paper. That should be acknowledged, and ideally should be discussed.  There are a handful of minor English disfluencies, misspellings, and minor LaTeX issues, such as reverse quotation marks. These should be corrected.  - General Discussion:  Paper is a nice contribution to the existing literature on character-based neural MT.

El formato simplemente pésimo, la redacción deja también bastante que desear, las figuras borrosas, tablas escaneadas de algún lugar sin referencia. El contenido no existe. Este debe ser uno de los artículos más malos que he visto en mi vida,
