Online advertising click-through rate (CTR) prediction is aimed at predicting the probability of a user clicking an ad,and it has undergone considerable development in recent years.One of the hot topics in this area is the construction of feature interact
The proliferation of massive datasets has led to significant interests in distributed algorithms for solving large-scale machine learning problems.However,the communication overhead is a major bottleneck that hampers the scalability of distributed machine
Most State-Of-The-Art (SOTA) Neural Machine Translation (NMT) systems today achieve outstanding results based only on large parallel corpora.The large-scale parallel corpora for high-resource languages is easily obtainable.However,the translation quality
A moisture advection scheme is an essential module of a numerical weather/climate model representing the horizontal transport of water vapor.The Piecewise Rational Method (PRM) scalar advection scheme in the Global/Regional Assimilation and Prediction Sys
A generalized non-affine nonlinear power system model is presented for a single machine bus power system with a Static Var Compensator (SVC) or State Var System (SVS) for hybrid Unmanned Aerial Vehicles (UAVs).The model is constructed by differential alge
研究瞬息万变的大气,并对其进行有效的预报、预测,离不开对初始状态信息的掌握,这需要通过对相关气象要素尽可能完整、准确的观测来实现.近两百年来,伴随着科技进步,人类不断探索实现对全球海、陆、空、天立体大气多种要素的观测方法,取得了巨大进步.面对不断增多的海量气象数据,气象学家一方面需要对数据的质量和应用方法进行严格把控,另一方面还要对如何使这些诸多类型的资料满足各种不同需求进行具体分析,包括哪些领域的需求已得到基本满足,哪些环节仍存在基本观测数据的缺失,从而影响到对实况的掌握和预报准确性.针对需求满足程度的
中国基础科学全面发展的一个重要标志,是1986年国家自然科学基金委员会的建立.从该年开始,基金委地学部开始资助大气科学基础研究项目.截至2021年,35年来,基金委以研究项目的遴选、资助和评估等过程为推动,不仅促成了我国大气科学研究的持续进步,更形成了一支核心研究机构和队伍.
Vehicle information on high-speed trains can not only determine whether the various parts of the train are working normally,but also predict the train\'s future operating status.How to obtain valuable information from massive vehicle data is a difficult
2019年,国家自然科学基金地学部以大气科学为试点,调整基金申请代码,从而实现优化大气学科资助布局、推进地学整体代码改进的目标.2020年和2021年的资助项目,大气科学(D05)被划分为3个板块和16个方向:即大气科学的分支学科(D0501～D0508)、支撑技术(D0509～D0512)和发展领域(D0513～D0515).
国家自然科学基金(NSFC)在促进我国基础科学研究方面,一直以来扮演着重要的角色.为了量化评估资助效果,分析给出大气科学支持项目产出的SCIE论文及影响力.科睿唯安Web of Science科学文献数据库于2008年9月开始,标注论文得到的科学基金资助信息,因此从精确性方面考虑,分析出版年为2009—2021年大气科学基金资助论文.利用数据库“基金资助机构(FO)”“授权号(FG)”字段检索立项项目的发文数据,文献类型为article or review,可以得到基金项目科学论文分布情况.
