James O. Ramsay
James O. Ramsay (born 5 September 1942) is a Canadian statistician and Professor Emeritus at McGill University, Montreal, who developed much of the statistical theory behind multidimensional scaling (MDS). Together with co-author Bernard Silverman, he is widely recognized as the founder of functional data analysis. He wrote four influential books and over 100 peer-reviewed articles in statistical and psychometric journals. In 1998, the Statistical Society of Canada (SSC) awarded him a gold medal for research in 1998. In 2012 the SCS awarded him with an honorary membership. He was president of the Psychometric Society in 1981–1982 and president of the SSC in 2002–2003. Over his career, "three of his papers were read to the Royal Statistical Society, and another won The Canadian Journal of Statistics 2000 Best Paper Award." In retirement, as of 2010, he continued to hold adjunct appointments at Department of Chemical Engineering, Queen's University and the Department of Mathem ...

Prince George, British Columbia
Prince George is the largest city in northern British Columbia, Canada, with a population of 74,004 in the metropolitan area. It is often called the province's "northern capital" or sometimes the "spruce capital" because it is the hub city for Northern BC. It is situated at the confluence of the Fraser and Nechako rivers, and at the crossroads of Highway 16 and Highway 97. History The origins of Prince George can be traced to the North West Company fur trading post of Fort George, which was established in 1807 by Simon Fraser and named in honour of King George III.Runnalls, F.E. A History of Prince George. 1946 The post was centred in the centuries-old homeland of the Lheidli T'enneh First Nation, whose very name means "people of the confluence of the two rivers." The Lheidli T'enneh name began to see official use around the 1990s and the band is otherwise historically referred to as Fort George Indian Band.George, N. D.

Ronald Melzack
Ronald Melzack (July 19, 1929 – December 22, 2019) was a Canadian psychologist and professor of psychology at McGill University. In 1965, he and Patrick David Wall revolutionized pain research by introducing the gate control theory of pain. In 1968, Melzack published an extension of the gate control theory, in which he asserted that pain is subjective and multidimensional because several parts of the brain contribute to it at the same time. During the mid-1970s, he developed the McGill Pain Questionnaire and became a founding member of the International Association for the Study of Pain. He also became the founding editor of '' Wall & Melzack's Textbook of Pain'' Melzack has received numerous honors including Prix du Québec (1994), the Order of Canada (1995), and the National Order of Quebec (2000). In 2010, he won the Grawemeyer Award for his research on the science of pain. Early life Melzack was born in Montreal, the son of Joseph Melzack, who worked in a clothing fact ...

Neural Network
A neural network is a network or circuit of biological neurons, or, in a modern sense, an artificial neural network, composed of artificial neurons or nodes. Thus, a neural network is either a biological neural network, made up of biological neurons, or an artificial neural network, used for solving artificial intelligence (AI) problems. The connections of the biological neuron are modeled in artificial neural networks as weights between nodes. A positive weight reflects an excitatory connection, while negative values mean inhibitory connections. All inputs are modified by a weight and summed. This activity is referred to as a linear combination. Finally, an activation function controls the amplitude of the output. For example, an acceptable range of output is usually between 0 and 1, or it could be −1 and 1. These artificial networks may be used for predictive modeling, adaptive control and applications where they can be trained via a dataset. Self-learning resulting from e ...

Donald Hebb
Donald Olding Hebb (July 22, 1904 – August 20, 1985) was a Canadian psychologist who was influential in the area of neuropsychology, where he sought to understand how the function of neurons contributed to psychological processes such as learning. He is best known for his theory of Hebbian learning, which he introduced in his classic 1949 work ''The Organization of Behavior''. He has been described as the father of neuropsychology and neural networks. A ''Review of General Psychology'' survey, published in 2002, ranked Hebb as the 19th most cited psychologist of the 20th century. His views on learning described behavior and thought in terms of brain function, explaining cognitive processes in terms of connections between neuron assemblies. Early life Donald Hebb was born in Chester, Nova Scotia, the oldest of four children of Arthur M. and M. Clara (Olding) Hebb, and lived there until the age of 16, when his parents moved to Dartmouth, Nova Scotia. Hebb's parents were both med ...

R (programming Language)
R is a programming language for statistical computing and graphics supported by the R Core Team and the R Foundation for Statistical Computing. Created by statisticians Ross Ihaka and Robert Gentleman, R is used among data miners, bioinformaticians and statisticians for data analysis and developing statistical software. Users have created packages to augment the functions of the R language. According to user surveys and studies of scholarly literature databases, R is one of the most commonly used programming languages used in data mining. R ranks 12th in the TIOBE index, a measure of programming language popularity, in which the language peaked in 8th place in August 2020. The official R software environment is an open-source free software environment within the GNU package, available under the GNU General Public License. It is written primarily in C, Fortran, and R itself (partially self-hosting). Precompiled executables are provided for various operating systems. R ...

S (programming Language)
S is a statistical programming language developed primarily by John Chambers and (in earlier versions) Rick Becker and Allan Wilks of Bell Laboratories. The aim of the language, as expressed by John Chambers, is "to turn ideas into software, quickly and faithfully". The modern implementation of S is R, a part of the GNU free software project. S-PLUS, a commercial product, was formerly sold by TIBCO Software. History "Old S" S is one of several statistical computing languages that were designed at Bell Laboratories, and first took form between 1975–1976. Up to that time, much of the statistical computing was done by directly calling Fortran subroutines; however, S was designed to offer an alternate and more interactive approach, motivated in part by exploratory data analysis advocated by John Tukey. Early design decisions that hold even today include interactive graphics devices (printers and character terminals at the time), and providing easily accessible documentation for ...

John Chambers (statistician)
John McKinley Chambers is the creator of the S programming language, and core member of the R programming language project. He was awarded the 1998 ACM Software System Award for developing S. Early life Chambers received a Bachelor of Science from the University of Toronto in 1963. He received a Master of Arts in 1965 and a PhD degree in 1966, both in statistics, from Harvard University. Career Chambers started at Bell Laboratories in 1966 as a member of its technical staff. From 1981 to 1983, he was the head of its Advanced Software Department and from 1983 to 1989 he was the head of its Statistics and Data Analysis Research Department. In 1989, he moved back to full-time research and in 1995, he became a distinguished member of the technical staff. In 1997, he was made the first Fellow of Bell Labs and was cited for "pioneering contributions to the field of statistical computing". He remained a distinguished member of the technical staff and a Fellow until his retirement from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
