A training data set is a data set of examples used during the learning process and is used to fit the parameters (e.g., weights) of, for example, a classifier. [9] [10]For classification tasks, a supervised learning algorithm looks at the training data set to determine, or learn, the optimal combinations of variables that will generate a good predictive model.

This page collects helpful resources — Web sites, books, journals, and so on — to assist in writing good mathematics articles. To follow the scientific citation guidelines adopted by WikiProject Mathematics, every article should cite high quality sources where readers can learn more about the topic. In the spirit of Wikipedia, most sources ...
Bayesian statistics are based on a different philosophical approach for proof of inference.The mathematical formula for Bayes's theorem is: [|] = [|] [] []The formula is read as the probability of the parameter (or hypothesis =h, as used in the notation on axioms) “given” the data (or empirical observation), where the horizontal bar refers to "given".
The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. [2] In the open data discipline, data set is the unit to measure the information released in a public open data repository. The European data ...
Statistical bias exists in numerous stages of the data collection and analysis process, including: the source of the data, the methods used to collect the data, the estimator chosen, and the methods used to analyze the data. Data analysts can take various measures at each stage of the process to reduce the impact of statistical bias in their ...
To help find sources, Wikipedians have developed a number of source-finding templates which link to searches most likely to find references suitable for use in articles. The most well-known of these is {{ find sources }} , an inline template which can be used almost anywhere.
Look through the journals sources page for more ideas on how to find the article. Reach out to the author(s) of the research paper by email and ask them for a copy. Note that websites like Sci-Hub offer free and direct access to academic journal articles, but there are legal questions about their use and neither the Wikimedia Foundation nor the ...
Search engines and academic databases are often used to find sources. When searching for sources, it is wise to skim-read everything available (including abstracts of papers you cannot fully access) to get a feel for expert opinion on the most important aspects of a topic. Each system has quirks, advantages, and disadvantages.
