v. t. e. Bootstrap aggregating, also called bagging (from b ootstrap agg regat ing ), is a machine learning ensemble meta-algorithm designed to improve the stability and accuracy of machine learning algorithms used in statistical classification and regression. It also reduces variance and helps to avoid overfitting.
In statistics, the jackknife (jackknife cross-validation) is a cross-validation technique and, therefore, a form of resampling . It is especially useful for bias and variance estimation. The jackknife pre-dates other common resampling methods such as the bootstrap. Given a sample of size , a jackknife estimator can be built by aggregating the ...
Jpred. Jpred v.4 is the latest version of the JPred Protein Secondary Structure Prediction Server [1] which provides predictions by the JNet algorithm, one of the most accurate methods for secondary structure prediction, [2] that has existed since 1998 in different versions. [3]
Tool (band) Tool is an American rock band from Los Angeles. Formed in 1990, the group consists of vocalist Maynard James Keenan, guitarist Adam Jones, drummer Danny Carey and bassist Justin Chancellor, the latter of whom replaced founding member Paul D'Amour in 1995. Tool has won four Grammy Awards, [1] performed worldwide tours, and produced ...
t. e. The Bootstrap Protocol ( BOOTP) is a computer networking protocol used in Internet Protocol networks to automatically assign an IP address to network devices from a configuration server. The BOOTP was originally defined in RFC 951 published in 1985. While some parts of BOOTP have been effectively superseded by the Dynamic Host ...
Near-field communication ( NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 centimetres (1.6 in) or less. [1] NFC offers a low-speed connection through a simple setup that can be used for the bootstrapping of capable wireless connections. [2]
Electronic authentication. Electronic authentication is the process of establishing confidence in user identities electronically presented to an information system. [1] Digital authentication, or e-authentication, may be used synonymously when referring to the authentication process that confirms or certifies a person's identity and works.
Bootstrapping is any test or metric that uses random sampling with replacement (e.g. mimicking the sampling process), and falls under the broader class of resampling methods. Bootstrapping assigns measures of accuracy ( bias, variance, confidence intervals, prediction error, etc.) to sample estimates.
