Distributed implementations of dependency discovery algorithms

Hemant Saxena, Lukasz Golab, Ihab F. Ilyas
2019 Proceedings of the VLDB Endowment  
We analyze the problem of discovering dependencies from distributed big data.  ...  To understand this space, we introduce six primitives shared by existing dependency discovery algorithms, corresponding to data processing steps separated by communication barriers.  ...  Minimal functional dependency: Let X ⊂ R and A ∈ R. A functional dependency (FD) X → A holds on r iff for every pair of tuples ti, tj ∈ r the following is true: if ti[X] = tj[X], then ti[A] = tj[A].  ...

Effective and complete discovery of order dependencies via set-based axiomatization

Jaroslaw Szlichta, Parke Godfrey, Lukasz Golab, Mehdi Kargar, Divesh Srivastava
2017 Proceedings of the VLDB Endowment  
Hence, proposals for automatic discovery have been made for some classes of ICs, such as functional dependencies (FDs), and recently, order dependencies (ODs).  ...  Using real and synthetic datasets, we experimentally show orders-ofmagnitude performance improvements over the prior stateof-the-art.  ...  Prior work has focused on functional dependencies (FDs) and extensions thereof, such as conditional FDs [4] .  ...

Discovering Graph Functional Dependencies

Wenfei Fan, Chunming Hu, Xueli Liu, Ping Lu
2018 Proceedings of the 2018 International Conference on Management of Data - SIGMOD '18  
This paper studies discovery of GFDs, a class of functional dependencies defined on graphs. We investigate the fixed-parameter tractability of three fundamental problems related to GFD discovery.  ...  We introduce notions of reduced GFDs and their topological support, and formalize the discovery problem for GFDs. We develop algorithms for discovering GFDs and computing their covers.  ...  We also implemented two baselines. (1) Algorithm ParArab splits the pattern mining and dependency discovery.  ...
