paragraph2vec工作受质疑

       Quoc V. Le ICML2014的工作《Distributed Representations of Sentences and Documents》一直饱受争议，很多学者都宣称其工作无法重现。

       ICLR2015文章《ENSEMBLE OF GENERATIVE ANDDISCRIMINATIVETECHNIQUES FORSENTIMENTANALYSIS OFMOVIEREVIEWS》在文章中直接对该工作进行了评价：

In our experiments, to match the results from (Le & Mikolov, 2014), we followed the suggestion by QuocLe to use hierarchical softmax instead of negative sampling. However, this produces the 92.6% accuracy resultonly when the training and test data are not shuffled. Thus, we consider this result to be invalid.
