The procedures for making a computer or a program function through its own actions.
(engineering)
A technique or device designed to bring itself into a desired state by means of its own action.

bootstrap

(operating system, compiler)
To load and initialise the operating system on a computer. Normally abbreviated to "boot". From the curious expression "to pull oneself up by one's bootstraps", one of the legendary feats of Baron von Munchhausen. The bootstrap loader is the program that runs on the computer before any (normal) program can run. Derived terms include reboot, cold boot, warm boot, soft boot and hard boot.

The term also applies to the use of a compiler to compile itself. The usual process is to write an interpreter for a language, L, in some other existing language. The compiler is then written in L and the interpreter is used to run it. This produces an executable for compiling programs in L from the source of the compiler in L. This technique is often used to verify the correctness of a compiler. It was first used in the LISP community.

Next, we survey several types of research that have followed and that share similar themes: multiview learning, bootstrapped lexicon induction, and bootstrapped pattern learning.
The sampling variance is the average variance from the bootstrapped sample with population weights.
On the other hand, the bootstrapped version of AIC still shows good improvements (PAD over 10) whereas FPE provides the smaller gains (PAD between 8.4 for [J.sub.2] and 9.6 for [J.sub.3]).
It is possible to derive an empirical distribution of bootstrapped values by doing this process again and again which provides a Monte Carlo approximation of the sampling distribution and also helps out in inference measures.
As indicated by Ray (2004), a major shortcoming of the bootstrapped procedure sketched above is that the underlying population density function f from which the initial data sample is drawn will not be properly represented by its estimator [??], from which pseudo-observations ([x.sup.*t.sub.j],[y.sup.*t.sub.j]) are drawn.
In contrast, our tests results are based on bootstrapped confidence intervals.
The coefficients of the parametric OLS and the mean and median values of the coefficients of the bootstrapped OLS and MLE methods share common features.
Bootstrapped neighbor-joining trees confirmed the identity of the new sequences obtained, which are closely related to HGA strains isolated in Europe and the United States (Figure).
The profile patterns obtained from reduced samples without bootstrapping were poorly matched with the major profiles, whereas the profile patterns from bootstrapped samples were well matched with the major profile patterns.
"Steve's quintessential character and visionary passion bootstrapped the personal computer revolution," said Galanos.
Bootstrapped preamplifiers have been reported [3, 4] that can keep the voltage drop on the photodiode very low resulting in an increased shunt resistance and better short circuit for the photodiode.
