Open data may include non-textual material such as maps, genomes, connectomes, chemical compounds, mathematical and scientific formulae, medical data, and practice, bioscience and biodiversity. A major barrier to the open data movement is the commercial value of data.
Data.gov is a U.S. Government website launched in late May 2009 by the Federal Chief Information Officer (CIO) of the United States, Vivek Kundra. Data.gov aims to improve public access to high value, machine-readable datasets generated by the Executive Branch of the Federal Government. [1] The site is a repository for Federal, state, local ...
These datasets are used in machine learning (ML) research and have been cited in peer-reviewed academic journals. Datasets are an integral part of the field of machine learning. Major advances in this field can result from advances in learning algorithms (such as deep learning ), computer hardware, and, less-intuitively, the availability of ...
The University of Montreal and Mila created the "COVID-19 Image Data Collection" in March which is a public data repository of chest imaging. [25] [26] [27] The Medical Imaging Databank in Valencian Region released a large dataset of chest imaging from Spain. [28] [29] The Italian Radiological Society is compiling an international online ...
Free statistical software is a practical alternative to commercial packages. Many of the free to use programs aim to be similar in function to commercial packages, in that they are general statistical packages that perform a variety of statistical analyses. Many other free to use programs were designed specifically for particular functions ...
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable, and each row corresponds to a given record of the data set in question. The data set lists values for each of the variables, such as for example ...
Anscombe's quartet comprises four datasets that have nearly identical simple descriptive statistics, yet have very different distributions and appear very different when graphed. Each dataset consists of eleven ( x , y) points. They were constructed in 1973 by the statistician Francis Anscombe to demonstrate both the importance of graphing data ...
Data science is an interdisciplinary field [10] focused on extracting knowledge from typically large data sets and applying the knowledge and insights from that data to solve problems in a wide range of application domains. The field encompasses preparing data for analysis, formulating data science problems, analyzing data, developing data ...
