Committers

This is the current list of people with access to push to the git repository with their user names. For technical details on how committing works, see Committing with Git. Note: This is just a list of people who currently have access to push to git; for information on current and previous contributors, see the contributor profiles section of the web site. Note: The names are listed here in order of first commit or when added as a committer, oldest first; this isn't intended to imply anything about depth of contribution.

Notes on the Commit Log

Hundreds of developers have successfully contributed work to PostgreSQL over more than 20 years, many acting as individuals, though also many representing academic institutions and both user and vendor companies. Both the "Author" and "Committer" fields of such patches will reflect the committer. The actual author of a patch, if different, is generally listed in the commit message; reviewers or others who contributed ideas or otherwise helped with the patch may also be listed. Many patches, in the form in which they are committed, are the work of multiple people: original author or authors, reviewer(s), and/or committer. As a result, no simple analysis of duration or depth of contribution over time is possible from the commit log. The project operates a system of careful peer review and even committers have their work checked by other committers and the community as a whole.

New Committers and Removing Committers

New committers are added approximately annually by the Core Team. Contributors to PostgreSQL are selected to be committers based on the following loose criteria:

  • several years of substantial contributions to the project
  • multiple and continuing code contributions
  • responsibility for maintenance of one or more areas of the codebase
  • track record of reviewing and helping other contributors with their patches
  • high quality code contributions which require very little revision or correction for commit
  • demonstrated understanding of the process and criteria for patch acceptance

Generally, new committers are selected March or April and announced at pgCon.

Committers who have become inactive and have not contributed significantly to the PostgreSQL project in several years are removed as committers. Again, the review process for this is approximately annual.

内容概要:本文提出了一种基于融合鱼鹰算法和柯西变异的改进麻雀优化算法(OCSSA),用于优化变分模态分解(VMD)的参数,进而结合卷积神经网络(CNN)与双向长短期记忆网络(BiLSTM)构建OCSSA-VMD-CNN-BILSTM模型,实现对轴承故障的高【轴承故障诊断】基于融合鱼鹰和柯西变异的麻雀优化算法OCSSA-VMD-CNN-BILSTM轴承诊断研究【西储大学数据】(Matlab代码实现)精度诊断。研究采用西储大学公开的轴承故障数据集进行实验验证,通过优化VMD的模态数和惩罚因子,有效提升了信号分解的准确性与稳定性,随后利用CNN提取故障特征,BiLSTM捕捉时间序列的深层依赖关系,最终实现故障类型的智能识别。该方法在提升故障诊断精度与鲁棒性方面表现出优越性能。; 适合人群:具备一定信号处理、机器学习基础,从事机械故障诊断、智能运维、工业大数据分析等相关领域的研究生、科研人员及工程技术人员。; 使用场景及目标:①解决传统VMD参数依赖人工经验选取的问题,实现参数自适应优化;②提升复杂工况下滚动轴承早期故障的识别准确率;③为智能制造与预测性维护提供可靠的技术支持。; 阅读建议:建议读者结合Matlab代码实现过程,深入理解OCSSA优化机制、VMD信号分解流程以及CNN-BiLSTM网络架构的设计逻辑,重点关注参数优化与故障分类的联动关系,并可通过更换数据集进一步验证模型泛化能力。
