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].

Es una aplicación interesante, sin embargo los KPI no deben ser equivalentes a las medidas que finalmente quedarán en la tabla de hechos. Por ejemplo, el indicador promedio de defunciones por año, se debe implementar a través de la medida "cantidad de defunciones" que es una medida aditiva y se puede agregar por los distintos niveles de la dimensión (así puede obtenerse el KPI promedio por dia, mes, trimestre, etc). Hay varias dimensiones que están agrupadas en el modelo, siendo que son distintas (por ejemplo, caracteristica_madre). Se debe corregir el diseño, es posible que los resultados obtenidos por el sistema estén con errores.

Overview: This work seems very promising, but I believe it should be compared with more baselines, and more precisely described and explained, from a signal processing point of view.  Pros: New descriptor Fast implementation  Cons: a) Lack of rigor b) Too long accordingly to the content c) The computational gain of the algorithm is not clear d) The work is not compared with its most obvious baseline: a scattering transform  I will detail each cons.  a) Section 1: The author  motivates the use of scattering transform because it defines a contraction of the space that relies on geometric features. " The nonlinearity used in the scattering network is the complex modulus which is piecewise linear." A real modulus is piecewise linear. A complex modulus has a shape of bell when interpreting C as R^2. Could you clarify? \Omega is not introduced.  Could you give a precise reference (page+paper) of this claim: “Higher order nonlinearity refers to |x|^2 instead of |x| as it is usually done in the scattering network.” ?  Section 2: The motivation of the non-linearity is not clear. First, this non-linearity might potentially increase a lot the variance of your architecture since it depends on higher moments(up to 4). I think a fair analysis would be to compute numerically the normalized variance (e.g. divided by the averaged l^2 norm), as a sanity check. Besides, one should prove that the energy is decreasing. It is not possible to argue that this architecture is similar to a scattering transform which has precise mathematical foundations and those results are required, since the setting is different.  Permutation is not a relevant variability.  The notion of sparsity during the whole paper sometimes refers to the number of 0 value, either the l^1 norm. Mathematically, a small value, even 10^-1000 is still a non 0 value.  Did you compute the graph of the figure 4 on the bird dataset? You might use a ratio instead for clarity.   The wavelet that is defined is not a morlet wavelet (

Ex Input:
El artículo presenta el proceso de construcción de un almacén de datos para implementar OLAP sobre datos de explotación de recursos marinos en las costas de Chile.  El problema está claramente delimitado y tiene aplicación práctica relevante para el país.  El trabajo presentado corresponde a un caso de uso muy completo y detalladamente documentado de técnicas bien conocidas de minería de datos.  El ABSTRACT debe ser editado para que represente una traducción apropiada y legible del RESUMEN.  No es evidente el aporte original del trabajo.  Las conclusiones originales del artículo dicen relación con el dominio de la aplicación (estadísticas de explotación de recursos marinos) y no con temas relevantes a la conferencia.  Debería completarse la información faltante en la bibliografía.
