Automatic knobs-tuning for DB2 using deep reinforcement learning
Bryson, Spencer C. (2021-12-01)Modern database management systems have hundreds of different configuration parameters (knobs) that control various aspects of how they behave and perform. These knobs must be properly tuned in order to maximize the ... -
Discovery of trend dependencies over time-series
Bode, Nicholas (2023-11-01)We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ... -
DistGALO: Distributed system for query problem determination
Mihaylov, Alexandar (2019-12-01)Query optimization is a quintessential element of modern Database Management Systems(DBMSs). Compile-time driven estimates and heuristics aid the compiler in selecting what is deemed the lowest cost Access Plan for a given ... -
JoVA-hinge: joint variational autoencoders for personalized recommendation with implicit feedback
Askari Firoozjayi, Bahare (2020-12-01)Recently, Variational Autoencoders (VAEs) have shown remarkable performance in collaborative filtering (CF) with implicit feedback. These existing recommendation models learn user representations to reconstruct or predict ...
