WebSep 2, 2024 · The results of the empirical evaluation demonstrate that the data-driven approach not only provides better accuracy than state-of-the-art learned components but … WebTo overcome these limitations, we take a different route: we propose to learn a pure data-driven model that can be used for different tasks such as query answering or cardinality …

NeuroCard: one cardinality estimator for all tables

WebSep 1, 2024 · Recently, machine learning based techniques have been proposed to effectively estimate cardinality, which can be broadly classified into query-driven and data-driven approaches. Query-driven approaches learn a regression model from a query to its cardinality; while data-driven approaches learn a distribution of tuples, select some … WebMar 1, 2024 · The typical approach for learned DBMS components is to capture the behavior by running a representative set of queries and use the observations to train a machine learning model. This workload-driven approach, however, has two major downsides. First, collecting the training data can be very expensive, since all queries need to be executed … da mario stuttgart
