Lp空间中基于投影的精确相似搜索算子

On Projection Based Operators in Lp space for Exact Similarity Search

Andreas Wichert, Catarina Moreira

摘要:

我们基于1-Lipschitz性质和投影算子研究了高维Lp范数的精确索引。描述了满足Lp范数的1-Lipschitz性质的正交投影。引入了由第一主成分定义的自适应投影。

英文摘要:

We investigate exact indexing for high dimensional Lp norms based on the 1-Lipschitz property and projection operators. The orthogonal projection that satisfies the 1-Lipschitz property for the Lp norm is described. The adaptive projection defined by the first principal component is introduced.
