Wenzhou
Wenzhou (pronounced ; Wenzhounese: Yuziou ”y33–11 tÉ•iɤu33–32 ), historically known as Wenchow is a prefecture-level city in southeastern Zhejiang province in the People's Republic of China. Wenzhou is located at the extreme south east of Zhejiang Province with its borders connecting to Lishui on the west, Taizhou on the north, and Fujian to the south. It is surrounded by mountains, the East China Sea, and 436 islands, while its lowlands are almost entirely along its East China Sea coast, which is nearly in length. Most of Wenzhou's area is mountainous as almost 76 percent of its surface area is classified as mountains and hills. It is said that Wenzhou has 7/10 mountains, 1/10 water, and 2/10 farmland. At the time of the 2010 Chinese census, 3,039,500 people lived in Wenzhou's urban area; the area under its jurisdiction (which includes three satellite cities and six counties) held a population of 9,122,100 of which 31.16% are non-local residents from outside of Wenz ...

High-dimensional Statistics
In statistical theory, the field of high-dimensional statistics studies data whose dimension is larger than typically considered in classical multivariate analysis. The area arose owing to the emergence of many modern data sets in which the dimension of the data vectors may be comparable to, or even larger than, the sample size, so that justification for the use of traditional techniques, often based on asymptotic arguments with the dimension held fixed as the sample size increased, was lacking. Examples Parameter estimation in linear models The most basic statistical model for the relationship between a covariate vector x \in \mathbb^p and a response variable y \in \mathbb is the linear model : y = x^\top \beta + \epsilon, where \beta \in \mathbb^p is an unknown parameter vector, and \epsilon is random noise with mean zero and variance \sigma^2. Given independent responses Y_1,\ldots,Y_n, with corresponding covariates x_1,\ldots,x_n, from this model, we can form the response ...

Vice-president
A vice president, also director in British English, is an officer in government or business who is below the president (chief executive officer) in rank. It can also refer to executive vice presidents, signifying that the vice president is on the executive branch of the government, university or company. The name comes from the Latin term ''vice'' meaning "in place of" and typically serves as ''pro tempore'' (Latin: ’for the time being’) to the president. In some countries, the vice president is called the ''deputy president''. In everyday speech, the abbreviation ''VP'' is used. In government In government, a vice president is a person whose primary responsibility is to act in place of the president on the event of the president's death, resignation or incapacity. Vice presidents are either elected jointly with the president as their running mate, or more rarely, appointed independently after the president's election. Most governments with vice presidents have one person ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Medical Imaging
Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging. Measurement and recording techniques that are not primarily designed to produce images, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others, represent other technologies that produce data susceptible to representation as a parameter graph versus time or maps that contain data about the measurement loca ...

Compressed Sensing
Compressed sensing (also known as compressive sensing, compressive sampling, or sparse sampling) is a signal processing technique for efficiently acquiring and reconstructing a Signal (electronics), signal, by finding solutions to Underdetermined system, underdetermined linear systems. This is based on the principle that, through optimization, the sparsity of a signal can be exploited to recover it from far fewer samples than required by the Nyquist–Shannon sampling theorem. There are two conditions under which recovery is possible. The first one is sparsity, which requires the signal to be sparse in some domain. The second one is incoherence, which is applied through the isometric property, which is sufficient for sparse signals. Overview A common goal of the engineering field of signal processing is to reconstruct a signal from a series of sampling measurements. In general, this task is impossible because there is no way to reconstruct a signal during the times that the signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Statistical Decision Theory
Decision theory (or the theory of choice; not to be confused with choice theory) is a branch of applied probability theory concerned with the theory of making decisions based on assigning probabilities to various factors and assigning numerical consequences to the outcome. There are three branches of decision theory: # Normative decision theory: Concerned with the identification of optimal decisions, where optimality is often determined by considering an ideal decision-maker who is able to calculate with perfect accuracy and is in some sense fully rational. # Prescriptive decision theory: Concerned with describing observed behaviors through the use of conceptual models, under the assumption that those making the decisions are behaving under some consistent rules. # Descriptive decision theory: Analyzes how individuals actually make the decisions that they do. Decision theory is closely related to the field of game theory and is an interdisciplinary topic, studied by econom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
