Problem: Este articulo no es un articulo de investigacion, ya que solo muestra como programar un robot mediante la herramienta de logica difusa. Este tema ya ha sido propuesto como solucion en navegacion de robots.
Solution: es
Explanation: This review is written in spanish. Hence, the label is 'es'.

Problem: The paper introduces a number of ideas / heuristics for learning and interpreting deep generative models of text (tf-idf weighting, a combination of using an inference networks with direct optimization of the variational parameters, a method for inducing context-sensitive word embeddings). Generally, the last bit is the most novel, interesting and promising one, however, I agree with the reviewers that empirical evaluation of this technique does not seem sufficient. Positive: -- the ideas are sensible -- the paper is reasonably well written and clear Negative -- most ideas are not so novel -- the word embedding method requires extra analysis / evaluation, comparison to other methods for producing context-sensitive embeddings, etc
