The Virtual Pooled Registry Cancer Linkage System (VPR-CLS) is a one-stop-shop designed to efficiently connect researchers with multiple cancer registries, thereby increasing access to, linkage with, and use of this valuable source of information. Researchers must be approved to use the VPR-CLS before submitting a new data request.

The VPR-CLS is a one-stop-shop designed to efficiently connect researchers with multiple cancer registries, thereby increasing access to, linkage with, and use of this valuable source of cancer surveillance information.

2023年1月10日 · Coordinated by the North American Association of Cancer Registries (NAACCR) with funding from the National Cancer Institute (NCI), the VPR-CLS provides a single location to facilitate minimal risk linkages between studies with an existing cohort and 45 U.S. registries representing approximately 95% of the U.S. population plus Puerto Rico.

The Virtual Pooled Registry Cancer Linkage System (VPR-CLS) is a secure online service designed to: efficiently connect researchers performing minimal risk linkage studies with multiple U.S. population-based cancer registries; perform linkages utilizing a single cohort file, standard linkage software, and consistent matching algorithms;

VPR-CLS Process Checklist for Researchers (January 16, 2025) The below checklists are intended to assist requestors in navigating and tracking the registry linkage process using the Virtual Pooled Registry Cancer Linkage System (VPR-CLS). The VPR-CLS includes automated workflows, notifications, and reminders for both requestors and

2025年1月29日 · vpr问题是一种经典的组合优化问题，主要研究如何优化车辆路径，以最小化总运输成本或最大程度地减少总运输时间。在vpr问题中，每个车辆都有一条或多条路径，每条路径上都有若干个节点（客户或配送点），节点之间的距离以及每个节点的需求量是已知的 ...

2020年10月1日 · *Heuristic names: guided local search (gls), simulated annealing (sa), genetic tabu search (gts) **ensemble: Using saving algorithm to quickly get an estimated number of routes, then use it as van count and use pca for initial solution

The Virtual Pooled Registry Cancer Linkage System (VPR-CLS) facilitates streamlined linkages between research studies and participating U.S. registries. Each year as part of the NAACCR Call for Data, VPR registries create a single, standardized VPR-CLS registry linkage file.

2025年3月10日 · 视觉位置识别（VPR）的目的是通过将图像作为检索问题来估计图像的位置。 VPR使用地理 标记图像 的数据库，并利用深度 神经网络 从每个图像中提取一个称为描述符的全局表示。 虽然VPR模型的训练数据通常来自不同的、地理上分散的来源（地理标记图像），但通常假设训练过程本身是集中的。 本研究通过联邦学习（FL）的视角重新审视了VPR的任务，解决了与此适应相关的几个关键挑战。 VPR数据本质上缺乏定义良好的类，并且模型通常使用对比学 …
