ML Based Lineage in Databases

no code implementations13 Sep 2021 Michael Leybovich, Oded Shmueli

We track the lineage of tuples throughout their database lifetime.

Efficient Approximate Search for Sets of Vectors

no code implementations14 Jul 2021 Michael Leybovich, Oded Shmueli

For the case where all sets are singleton sets, essentially each is a single vector, there are known efficient approximate search algorithms, e. g., approximated versions of tree search algorithms, locality-sensitive hashing (LSH), vector quantization (VQ) and proximity graph algorithms.

NN-based Transformation of Any SQL Cardinality Estimator for Handling DISTINCT, AND, OR and NOT

no code implementations15 Apr 2020 Rojeh Hayek, Oded Shmueli

Using the predicted percentages obtained via PUNQ, we are able to transform any cardinality estimation method that only estimates for conjunctive queries, and which estimates cardinalities with duplicates (e. g., MSCN), to a method that estimates queries cardinalities without duplicates.

Improved Cardinality Estimation by Learning Queries Containment Rates

no code implementations21 Aug 2019 Rojeh Hayek, Oded Shmueli

Experimentally, our novel approach for estimating cardinalities, using containment rates between queries, on a challenging real-world database, realizes significant improvements to state of the art cardinality estimation methods.

Cognitive Database: A Step towards Endowing Relational Databases with Artificial Intelligence Capabilities

no code implementations19 Dec 2017 Rajesh Bordawekar, Bortik Bandyopadhyay, Oded Shmueli

We propose Cognitive Databases, an approach for transparently enabling Artificial Intelligence (AI) capabilities in relational databases.
