我们考虑将一对数据库与相关条目对齐的问题。我们在联合分布中引入了一种新的相关性度量,我们称之为周期互信息。这一措施具有操作意义:它确定对于任何算法是否可以准确恢复数据库条目之间的对应关系。此外,还有一种高效的数据库比对算法,可以达到这个信息论阈值。
We consider the problem of aligning a pair of databases with correlated entries. We introduce a new measure of correlation in a joint distribution that we call cycle mutual information. This measure has operational significance: it determines whether exact recovery of the correspondence between database entries is possible for any algorithm. Additionally, there is an efficient algorithm for database alignment that achieves this information theoretic threshold.
