Input: Consider Input: This paper proposed a macro discourse structure scheme. The authors carried out a pilot study annotating a corpus consisting of 97 news articles from Chinese treebank 8.0. They then built a model to recognize the primary-secondary relations and 5 discourse relations (joint, elaboration, sequence, background, cause-result) in this corpus.  The paper is poorly written and I have difficulties to follow it. I strongly suggest that the authors should find a native English speaker to carefully proofread the paper. Regarding the content, I have several concerns:   1 The logic of the paper is not clear and justifiable:  1) what are "logical semantics" and "pragmatic function"(line 115-116)? I'd prefer the authors to define them properly.  2) macro discourse structure: there are some conflicts of the definition between macro structure and micro structure. Figure 4 demonstrates the combination of macro discourse structure and micro discourse structure. There, the micro discourse structure is presented *within paragraphs*. However, in the specific example of micro discourse structure shown in Figure 6, the micro-level discourse structure is *beyond the paragraph boundary* and captures the discourse relations across paragraphs. This kind of micro-level discourse structure is indeed similar to the macro structure proposed by the authors in Figure 5, and it's also genre independent. So, why can't we just use the structure in Figure 6? What's the advantage of macro discourse structure proposed in Figure 5? For me, it's genre dependent and doesn't provide richer information compared to Figure 6.  By the way, why sentence 6 and sentence 15 are missing in Figure 5? Is it because they are subtitles? But sentence 12 which is a subtitle is present there.  2 Corpus construction (section 4) is not informative enough: without a detailed example, it's hard to know the meaning of "discourse topic, lead, abstract, paragraph topics (line 627-629)". And you were saying you "explore the relationships between micro-structure and macro-structure", but I can't find the correspondent part.  Table 4 is about agreement study The authors claimed "Its very difficult to achieve high consistence because the judgments of relation and structure are very subjective. Our measurement data is only taken on the layer of leaf nodes."--------> First, what are the leaf nodes? In the macro-level, they are paragraphs; in the micro-level, they are EDUs. Should we report the agreement study for macro-level and micro-level separately? Second, it seems for me that the authors only take a subset of data to measure the agreement. This doesn't reflect the overall quality of the whole corpus, i.e., high agreement on the leaf nodes annotation doesn't ensure that we will get high agreement on the non-leaf nodes annotation.  Some other unclear parts in section 4:  Table 4: "discourse structure, discourse relation" are not clear, what is discourse structure and what is discourse relation?  Table 5: "amount of macro discourse relations", still not clear to me, you mean the discourse relations between paragraphs? But in Figure 6, these relations can exist both between sentences and between paragraphs.  3 Experiments: since the main purpose of the paper is to provide richer discourse structure (both on macro and micro level), I would expect to see some initial results in this direction. The current experiment is not very convincing: a) no strong baselines; b) features are not clearly described and motivated; c) I don't understand why only a sub set of discourse relations from Table 6 is chosen to perform the experiment of discourse relation recognition.  In general, I think the paper needs major improvement and currently it is not ready for acceptance.

Input: Consider Input: The authors proposed to use leaky rectified linear units replacing binary units in Gaussian RBM.  A sampling method was presented to train the leaky-ReLU RBM. In the experimental section, AIS estimated likelihood on Cifar10 and SVHN were reported.   It's interesting for trying different nonlinear hidden units for RBM. However, there are some concerns for the current work.  1. The author did not explain why the proposed sampling method (Alg. 2) is correct. And the additional computation cost (the inner loop and the projection) should be discussed.  2. The results (both the resulting likelihood and the generative samples) of Gaussian RBM are much worse than what we have experienced. It seems that the Gaussian RBM were not trained properly.  3. The representation learned from a good generative model often helps the classification task when there are fewer label samples. Gaussian RBM works well for texture synthesis tasks in which mixing is an important issue. The authors are encouraged to do more experiments in these two direction.

Input: Consider Input: El trabajo presenta un report sobre aspectos de seguridad del producto software dependiendo de las tecnologías utilizadas para su desarrollo. Creo que falta rigor científico en la búsqueda de información. De hecho no es claramente explicado cómo se obtuvo la información por lo que queda como una monografía o marco teórico de un tema a investigar. No obstante, el estudio está bien presentado y su estructura es de calidad técnica. Creo que con una búsqueda en artículo de investigación puede ser mejorado.
