TASK DEFINITION: In this task, you are given a paper review. Based on the review, your job is to identify language and generate "en" if the review is in English or generate "es" if the review is in Spanish. Note that URLs in the text have been replaced with [Link].
PROBLEM: Taking into account the loss in the binarization step through a proximal Newton algorithm is a nice idea. This is at least one approach to bringing in the missing loss in the binarization step, which has recently gone from a two step process of train and binarize to a single step simultaneous train/compress. Performance on a few small tasks show the benefit. It would be nice to see some results on substantial networks and tasks which really need compression on embedded systems (a point made in the introduction). Is it necessary to discuss exploding/vanishing gradients when the RNN experiments are carried out by an LSTM, and handled by the cell error carousel? We see the desire to tie into proposition 2, but not clear that the degradation we see in the binary connect is related. Adam is used in the LSTM optimization, was gradient clipping really needed, or is the degradation of binary connect simply related to capacity? For proposition 3.1, theorem 3.1 and proposition 3.2 put the pointers to proofs in appendix.

PROBLEM: The authors propose a RNN-method for time-series classification with missing values, that can make use of potential information in missing values. It is based on a simple linear imputation of missing values with learnable parameters. Furthermore, time-intervals between missing values are computed and used to scale the RNN computation downstream. The authors demonstrate that their method outperforms reasonable baselines on (small to mid-sized) real world datasets. The paper is clearly written. IMO the authors propose a reasonable approach for dealing with missing values for their intended application domain, where data is not abundant and requires smallish models. I’m somewhat sceptical if the benefits would carry over to big datasets, where more general, less handcrafted multi-layer RNNs are an option.

PROBLEM: This manuscript addresses an interesting solution based in machine learning techniques to classify spectra legacy data of the Hubble Space Telescope in order to publish the results and "good" spectra in Internet to scientific community. The manuscript is well-written and results are robust. Experiment is sound and the manuscript seems acceptable in the current form. The work can be short, but very interesting to the Infonor and JCC community.  The main problem of the paper is that it is difficult to compare results for the classifiers utilized. A confusion matrix and parameters for each classifier could clarify results.
