Big data concepts theories and applications pdf
Big Data: Survey, Technologies, Opportunities, and ChallengesPetrophysics is a pivotal discipline that bridges engineering and geosciences for reservoir characterization and development. New sensor technologies have enabled real-time streaming of large-volume, multi-scale, and high-dimensional petrophysical data into our databases. Petrophysical data types are extremely diverse, and include numeric curves, arrays, waveforms, images, maps, 3-D volumes, and texts. All data can be indexed with depth continuous or discrete or time. Petrophysical data exhibits all the "7V" characteristics of big data, i. This paper will give an overview of both theories and applications of machine learning methods as applicable to petrophysical big data analysis.

Big Data in Psychology: Introduction to Special Issue
Big Data has gained much attention from the academia and the IT industry. In the digital and computing world, information is generated and collected at a rate that rapidly exceeds the boundary range. Currently, over 2 billion people worldwide are connected to the Internet, and over 5 billion individuals own mobile phones. By , 50 billion devices are expected to be connected to the Internet. At this point, predicted data production will be 44 times greater than that in As information is transferred and shared at light speed on optic fiber and wireless networks, the volume of data and the speed of market growth increase.
Written by world-renowned leaders in Big Data, this book explores the problems, possible solutions and directions for Big Data in research and practice. The theoretical research ranges from Big Data representation, modeling and topology to distribution and dimension reducing. Chapters also investigate the many disciplines that involve Big Data, such as statistics, data mining, machine learning, networking, algorithms, security and differential geometry. The last section of this book introduces Big Data applications from different communities, such as business, engineering and science. Skip to main content Skip to table of contents.

Data with many cases rows offer greater statistical power , while data with higher complexity more attributes or columns may lead to a higher false discovery rate. Big data was originally associated with three key concepts: volume , variety , and velocity. Therefore, big data often includes data with sizes that exceed the capacity of traditional usual software to process within an acceptable time  and value. Current usage of the term big data tends to refer to the use of predictive analytics , user behavior analytics , or certain other advanced data analytics methods that extract value from data, and seldom to a particular size of data set. Scientists encounter limitations in e-Science work, including meteorology , genomics ,  connectomics , complex physics simulations, biology and environmental research.
The introduction to this special issue on psychological research involving big data summarizes the highlights of 10 articles that address a number of important and inspiring perspectives, issues, and applications. Four common themes that emerge in the articles with respect to psychological research conducted in the area of big data are mentioned, including: 1. The benefits of collaboration across disciplines, such as those in the social sciences, applied statistics, and computer science. Doing so assists in grounding big data research in sound theory and practice, as well as in affording effective data retrieval and analysis. Availability of large datasets on Facebook, Twitter, and other social media sites that provide a psychological window into the attitudes and behaviors of a broad spectrum of the population. Identifying, addressing, and being sensitive to ethical considerations when analyzing large datasets gained from public or private sources.
