- Strengths: The idea of hard monotonic attention is new and substantially different from others.  - Weaknesses: The experiment results on morphological inflection generation is somewhat mixed. The proposed model is effective if the amount of training data is small (such as CELEX). It is also effective if the alignment is mostly monotonic and less context sensitive (such as Russian, German and Spanish).  - General Discussion:  The authors proposed a novel neural model for morphological inflection generation which uses "hard attention", character alignments separately obtained by using a Bayesian method for transliteration. It is substantially different from the previous state of the art neural model for the task which uses "soft attention", where character alignment and conversion are solved jointly in the probabilistic model.  The idea is novel and sound. The paper is clearly written. The experiment is comprehensive. The only concern is that the proposed method is not necessarily the state of the art in all conditions. It is suitable for the task with mostly monotonic alignment and with less context sensitive phenomena. The paper would be more convincing if it describe the practical merits of the proposed method, such as the ease of implementation and computational cost.

El artículo muestra un estudio de aplicación de Algoritmos Genéticos para resolver un sistema de ecuaciones en imágenes ópticas de detección de tumores y seguimiento de tratamientos oncológicos.  El trabajo está bien escrito y tiene un alto nivel de detalle técnico. Sin embargo, no muestra explícitamente cuáles son sus principales contribuciones. En este sentido sería conveniente ampliar la Sección de Introducción para entregar al lector un detalle de las principales contribuciones del trabajo y además incluir en esta sección (o en una sección de Trabajo Relacionados o Estado del Arte) un mayor detalle de otros trabajos previos que estén relacionados con la propuesta de los autores.  En el ámbito de aplicación de Algoritmos Genéticos para resolución de sistemas de ecuaciones, este trabajo no presenta un aporte novedoso, ya que existen varios trabajos previos orientados a este tipo de solución. Respecto al análisis de imágenes y reconocimiento de patrones, hay trabajos previos que ya utilizan Algoritmos Genéticos para este tipo de propuestas, tales como Dourdan, 2015.  Sería conveniente haber tenido una comparativa con otros métodos de Machine Learning que se han aplicado ampliamente al reconocimiento de imágenes tales como k-means o PCA.  Menores: - En la figura 10 no se visualiza bien la serie Solución AG por la cantidad de puntos graficados. - Último párrafo de Conclusiones. " ... la ventaja de trabajar con heurísticas como el algoritmo genéticos..." debiera ser "... la ventaja de trabajar con heurísticas como los algoritmos genéticos...". - Último párrafo de Conclusiones. "... es factible que el AG de buena aproximación..." creo que se debe cambiar la redacción, no se entiende en la primera lectura. -- Referencias. Las referencias a trabajos de Pattern Recognition es antigua 1997, creo que hay referencias más actualizadas y hay mayor cantidad de trabajos donde se aplican diversas técnicas de machine learning para reconocimiento de patrones, desde supervised a unsupervised métodos.

This paper presents an approach to tag word senses with temporal information (past, present, future or atemporal). They model the problem using a graph-based semi-supervised classification algorithm that allows to combine item specific information - such as the presence of some temporal indicators in the glosses - and the structure of Wordnet - that is semantic relations between synsets â, and to take into account unlabeled data. They perform a full annotation of Wordnet, based on a set of training data labeled in a previous work and using the rest of Wordnet as unlabeled data. Specifically, they take advantage of the structure of the label set by breaking the task into a binary formulation (temporal vs atemporal), then using the data labeled as temporal to perform a finer grained tagging (past, present or future). In order to intrinsically evaluate their approach, they annotate a subset of synsets in Wordnet using crowd-sourcing. They compare their system to the results obtained by a state-of-the-art time tagger (Stanford's SUTime) using an heuristic as a backup strategy, and to previous works. They obtain improvements around 11% in accuracy, and show that their approach allows performance higher than previous systems using only 400 labeled data. Finally, they perform an evaluation of their resource on an existing task (TempEval-3) and show improvements of about 10% in F1 on 4 labels.  This paper is well-constructed and generally clear, the approach seems sound and well justified. This work led to the development of a resource with fine grained temporal information at the word sense level that would be made available and could be used to improve various NLP tasks. I have a few remarks, especially concerning the settings of the experiments.  I think that more information should be given on the task performed in the extrinsic evaluation section. An example could be useful to understand what the system is trying to predict (the features describe âentity pairsâ but it has not been made clear before what are these pairs) and what are the features (especially, what are the entity attributes? What is the POS for a pair, is it one dimension or two? Are the lemmas obtained automatically?). The sentence describing the labels used is confusing, I'm not sure to understand what âevent to document creation timeâ and âevent to same sentence eventâ means, are they the kind of pairs considered? Are they relations (as they are described as relation at the beginning of p.8)? I find unclear the footnote about the 14 relations: why the other relations have to be ignored, what makes a mapping too âcomplexâ? Also, are the scores macro or micro averaged? Finally, the ablation study seems to indicate a possible redundancy between Lexica and Entity with quite close scores, any clue about this behavior?  I have also some questions about the use of the SVM.  For the extrinsic evaluation, the authors say that they optimized the parameters of the algorithm: what are these parameters?  And since a SVM is also used within the MinCut framework, is it optimized and how? Finally, if it's the LibSVM library that is used (Weka wrapper), I think a reference to LibSVM should be included.   Other remarks: - It would be interesting to have the number of examples per label in the gold data, the figures are given for coarse grained labels (127 temporal vs 271 atemporal), but not for the finer grained. - It would also be nice to have an idea of the number of words that are ambiguous at the temporal level, words like âpresentâ. - It is said in the caption of the table 3 that the results presented are âsignificantly betterâ but no significancy test is indicated, neither any p-value.  Minor remarks: - Related work: what kind of task was performed in (Filannino and Nenadic, 2014)? - Related work: ârequires a post-calibration procedureâ, needs a reference (and p.4 in 3.3 footnote it would be clearer to explain calibration) - Related work: âtheir model differ from oursâ, in what? - Table 3 is really too small: maybe, remove the parenthesis, put the â(p,r,f1)â in the caption and give only two scores, e.g. prec and f1. The caption should also be reduced. - Information in table 4 would be better represented using a graph. - Beginning of p.7: 1064 â 1264 - TempEval-3: reference ? - table 6: would be made clearer by ordering the scores for one column - p.5, paragraph 3: atemporal) â atemporal
