This web page provides a comprehensive list of datasets used in machine learning research, with various attributes such as type, scope, language, license, and file format. It also includes links to data portals and repositories for different subtypes of datasets, such as image, text, and audio data.
Learn how machine learning algorithms use different data sets to learn, tune, and evaluate their performance. Find out the definitions, examples, and strategies of training, validation, and test data sets.
Learn about the process and methods of selecting a subset of individuals from a population to estimate its characteristics. Find out the history, types, and applications of sampling in statistics, quality assurance, and survey methodology.
A Student's t-test is a statistical test to compare the means of two groups and see if they are significantly different. It is based on the t-distribution, which depends on the sample size and the variance of the populations. Learn about the history, types and uses of the t-test.
Statistics is the discipline that deals with data collection, analysis, interpretation, and presentation. It uses mathematical techniques, probability theory, and inference to draw conclusions from data that are subject to uncertainty and variation.
The set of images in the MNIST database was created in 1994 as a combination of two of NIST's databases: Special Database 1; and Special Database 3. [16]Special Database 1 and Special Database 3 consist of digits written by high school students and employees of the United States Census Bureau, respectively.
Learn about the t distribution, a continuous probability distribution that generalizes the normal distribution and is used in statistical tests and confidence intervals. Find out its history, definition, properties, moments, and special cases.
Statistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. It involves selecting a statistical model, making assumptions, and drawing conclusions about a population or a hypothesis.
