Dealing With Ratio Metrics in A/B Testing at the Presence of Intra-User Correlation and Segments
Keyu Nie, Yinfei Kong, Ted Tao Yuan +1
We study ratio metrics in A/B testing at the presence of correlation among observations coming from the same user and provides practical guidance especially when two metrics contra…
Efficient Multivariate Bandit Algorithm with Path Planning
Keyu Nie, Zezhong Zhang, Ted Tao Yuan +2
In this paper, we solve the arms exponential exploding issue in multivariate Multi-Armed Bandit (Multivariate-MAB) problem when the arm dimension hierarchy is considered. We propos…
Relation Embedding with Dihedral Group in Knowledge Graph
Canran Xu, Ruijiang Li
Link prediction is critical for the application of incomplete knowledge graph (KG) in the downstream tasks. As a family of effective approaches for link predictions, embedding meth…
Algorithms to compute the Burrows-Wheeler Similarity Distribution
Felipe A. Louza, Guilherme P. Telles, Simon Gog +1
The Burrows-Wheeler transform (BWT) is a well studied text transformation widely used in data compression and text indexing. The BWT of two strings can also provide similarity meas…
