2022年4月29日 · With the sensitivity arising from the large collecting area of the GBT and clean radio-frequency environment of the Green Bank site, the KFPA has been a popular instrument among GBT users, including those in the areas of galaxy …

NRAO will hold an internal review of the KFPA imaging pipeline on Thursday June 17, starting with the science lunch discussion of science priorities for GBT imaging projects. We will continue at 1:15 with the agenda centered on scientific requirements for the pipeline. We intend to be finished in time for the technology development talk.

• VLBI on the GBT: Time available for VLBI on the GBT will be dramatically reduced compared to past observing semesters due to its new partnership arrangement. Proposers should only include the GBT in the proposal if it is essential for the science and if it is clearly justified in the text of the proposal. All Very Long Baseline ...

The GBT is operated by the Green Bank Observatory (GBO), a facility of the National Science Foundation operated under cooperative agreement by Associated Universities Incorporated. The GBT

2020年5月16日 · 梯度提升树 (GBT) 的一个核心思想是 利用损失函数的负梯度在当前模型的值作为残差的近似值，本质上是 对损失函数进行一阶泰勒展开，从而拟合一个回归树。 至于为什么用损失函数的负梯度替代残差，看这里: https://www.cnblogs.com/jiading/articles/12899791.html. 看了之前的不少回答感觉都没答到点子上，题主问的是 为什么前向分步时不直接拟合残差？ 简单来讲就一句话， 为了可以扩展到更复杂的损失函数中。 这时候你可能就有疑问了，难道不是所有 …

认证标准，作为一种国际通用的质量评价体系，旨在通过对产品、服务和管理体系进行全面、客观、公正的评估，确保它们符合特定的质量要求和技术规范。 这一体系的建立，不仅有助于企业提升产品质量和服务水平，还能为消费者提供明确的购买指南，促进市场的健康发展。 本篇文章将为大家解读ISO和GB/T等标准分别代表什么以及他们之间的联系。 ISO，即国际标准化组织（英文全称International Organization for Standardization，简称ISO）。 它成立于1947年，是一个全球性 …
