ClickHouse是俄罗斯的Yandex于2016年开源的列式存储数据库(DBMS),使用C++语言编写,主要用于在线分析处理查询(OLAP),能够使用SQL查询实时生成分析数据报告。 OLAP(On-Line Analytical Processing)翻译为联机分析处理,专注于分析处理,从对数据库操作来看,OLAP是对数据的查询; OLTP(on-line transaction processing)翻译为联机...
Graph Neural Networks (GNNs) have emerged as the predominant paradigm for learning from graph-structured data, offering a wide range of applications from social network analysis to bioinformatics. Despite their versatility, GNNs face challenges such as lack of generalization and poor interpretability, wh...
Explain and graph an event which leads to lower prices and lower quantity produced of a certain good. Discuss four ways of dealing with negative externalities. Determine each of these statements below can be defined as a 'True of Network Goods' or 'Not True of Network Goods.' A) The good...
Networked systems emerge and subsequently evolve. Although several models describe the process of network evolution, researchers know far less about the initial process of network emergence. Here, we report temporal survey results of a real-world social
Here we propose a simple and generally applicable model of social network structure. We consider the emergence of network structure as a result of social inheritance, in which newborns are likely to bond with maternal contacts, and via forming bonds randomly. We compare model output with data ...

EBM is an interpretable model developed at Microsoft Research*. It uses modern machine learning techniques like bagging, gradient boosting, and automatic interaction detection to breathe new life into traditional GAMs (Generalized Additive Models). This makes EBMs as accurate as state-of-the-art techn...
Social Networks in Economic History: Opportunities and Challenges 2019, Explorations in Economic History Citation Excerpt : Network studies are growing rapidly in economic history, and it is likely that other areas will soon be the object of network analysis, especially as the costs of acquiring larg...
Considering the order of decreasing relevance from top to bottom of the graph, it can be observed that the economic variables such as compensation of employees, GDP and number of hours worked are some of the features which mainly affect the odds of a NUTS2 region to be at high risk of ex...
We combine these factors as explanatory variables in different exponential random graph models (ERGMs) to assess the relative strength of prestige and homophily for the actors' link formation. We analyze the climate change discourse in a hyperlink network formed by US civil society actors from ...
