请问这个平滑策略的根据是什么呢，谢谢！ |
|
曲线形状 |
|
还有两个问题想问一下您，您的代码中_flat_sum_array这个函数是将句子中各个词的词向量叠加吗？ |
|
请教一下，是我用法不对还是词库的问题，"舒服"的近义词为什么是"难受"？ |
|
计算依据非监督的word2vec, 是利用前后词作为特征，所以也会出现反义词的时候。使用机器学习会有准确率的问题，并不保证100%都是准确的近义词。

句子相似度比较每次得到的结果居然不一致。。。 第二次运行结果： 第三次运行结果： |
|
为什么是词向量相似度和编辑距离相似度相乘而不是相加呢？ |
|
在这个问题下学到很多，我的理解是： |

比如，句子的向量表示为每个词的vector取平均，然后cos
或者用softcos、WMD之类？
