Document Embedding with Paragraph Vectors
作者评估了大型维基百科和arXiv文档检索任务上的段落向量，并将结果与LDA，BoW和单词向量平均模型进行了比较。 段落向量的性能优于或匹配其他模型的性能。 作者展示了嵌入维数如何影响结果。 此外，作者发现，人们可以对段落矢量执行算术运算，并获得有意义的结果，并以可视化和文档示例的形式呈现定性分析。
数据集
通过构造三元组来评估准确性，其中三对是彼此接近的，而第三项是无关的（或关联性较低）。 余弦相似度用于评估语义紧密度。
Wikipedia (hand-built) PV: 93%
Wikipedia (hand-built) LDA: 82%
Wikipedia (distantly supervised) PV: 78.8%
Wikipedia (distantly supervised) LDA: 67.7%
arXiv PV: 85%
arXiv LDA: 85%
关键点

联合训练PV和单词向量似乎可以提高性能。
将Softsoft分层用作大词汇量的霍夫曼树
仅使用PV-BoW模型，因为它效率更高。

问题/注释

为什么arXiv和Wikipedia任务之间的性能差异？ BoW在Wikipedia上的表现令人惊讶，但arXiv却不如。 LDA相反。

C++ Vectors

Vectors 包含着一系列连续存储的元素,其行为和数组类似。访问Vector中的任意元素或从末尾添加元素都可以在常量级时间复杂度内完成，而查找特定值的元素所处的位置或是在Vector中插入元素则是线性时间复杂度。

Constructors
构造函数
Operators

assign()
对Vector中的元素赋值
at()
返回指定位置的元素
back()

empty()
判断Vector是否为空（返回true时为空）
end()

erase()
删除指定元素
front()
返回第一个元素
get_allocator()
返回vector的内存分配器
insert()

pop_back()
移除最后一个元素
push_back()
在Vector最后添加一个元素
rbegin()
返回Vector尾部的逆迭代器
rend()

reserve()
设置Vector最小的元素容纳数量
resize()
改变Vector元素数量的大小
size()
返回Vector元素数量的大小
swap()
