A Learned Query Rewrite System
Proceedings of the VLDB Endowment, 2023Query rewriting is a challenging task that transforms a SQL query to improve its performance while maintaining its result set. However, it is difficult to rewrite SQL queries, which often involve complex logical structures, and there are numerous ...

WeTune: Automatic Discovery and Verification of Query Rewrite Rules
SIGMOD Conference, 2022Query rewriting transforms a relational database query into an equivalent but more efficient one, which is crucial for the performance of database-backed applications. Such rewriting relies on pre-specified rewrite rules.

A Learned Query Rewrite System using Monte Carlo Tree Search
Proceedings of the VLDB Endowment, 2021Query rewrite transforms a SQL query into an equivalent one but with higher performance. However, SQL rewrite is an NP-hard problem, and existing approaches adopt heuristics to rewrite the queries. These heuristics have two main limitations. First, the

Computer Vision and Pattern Recognition
Recent studies have drawn attention to the untapped potential of the “star operation” (element-wise multiplication) in network design. While intuitive explanations abound, the foundational rationale behind its application remains largely unexplored.

R-Bot: An LLM-based Query Rewrite System
Proceedings of the VLDB EndowmentQuery rewrite is essential for optimizing SQL queries to improve their execution efficiency without changing their results. Traditionally, this task has been tackled through heuristic and learning-based methods, each with its limitations in terms of ...

Rewrite Rules for Debugging Student Programs in Programming Tutors
IEEE Transactions on Learning Technologies, 2018Data-driven intelligent tutoring systems learn to provide feedback based on past student behavior, reducing the effort required for their development. A major obstacle to applying data-driven methods in the programming domain is the lack of meaningful ...

The Graph Grammar Library - a generic framework for chemical graph rewrite systems
International Conference on Model Transformation, 2013Graph rewrite systems are powerful tools to model and study complex problems in various fields of research. Their successful application to chemical reaction modelling on a molecular level was shown but no appropriate and simple system is available at ...

Abstract In this chapter the author describes the process of fine-tuning one’s song after it is written. Rewriting is one of the most crucial steps in the songwriting process, and the reader is prompted to boldly embrace the journey to create a perfect union between the music, melody, and words, carefully examining each part of the song ...
