Определение bootstrapping в Английский Язык Английский Язык словарь
The process of setting up an application to interact with CORBA objects that are located within the WebLogic Enterprise domain
The idea that improving a capability on which other capabilities depend automatically improves the dependent capabilities
An iterative calculation technique, often used in the construction of specialized time series For example, the calculation of forward rates from traditional yield curves uses an iterative process to extract the implied rate for each forward period
In phylogenetic analysis: Perform analysis x number of times, with subtle randomization of the input data The the number of times a particular branch is formed in the tree (out of the x times) can be used to estimate its probability, which can be indicated on a consensus tree
Training data sets are created by re-sampling with replacement from the original training set, so data records may occur more than once In other words, this method treats a sample as if it were the entire population Usually, final estimates are obtained by taking the average of the estimates from each of the bootstrap test sets
A means of finding creative ways to support a start-up business until it turns profitable This method may include negotiating delayed payment to suppliers and advances from potential partners and customers
This term has two meanings First, it refers to the procedure where coupon bonds are used to generate the set of zero-coupon bond prices Second, it means the use of historical returns to create an empirical probability distribution for returns
In business, this term refers to the process of financing a business by internally generated cash flow as opposed to "kickstarting" the company with external investment capital It means keeping salaries and expenses down while generating customer sales to fuel the growth of the venture
A means of finding creative ways to support a startup business until it turns profitable This method may include negotiating delayed payment to suppliers and advances from potential partners and customers
In this option, bootstrap samples are drawn from the original data points with replacement So, it is possible to draw one data point several times and others not at all The fit process is repeated using such a bootstrap sample The starting point of the parameters is always the result of the fit of the original set It is further possible that a fit is rejected if no `good' fit is obtained The sets of parameter estimates of the bootstrap samples are combined to get an idea of the distribution of the estimates A log is kept of all fitted samples
Any method or instance of estimating properties of an estimator (such as its variance) by measuring those properties when sampling from an approximating distribution
A software program for initiating the operation of a computer The function of the program is to set up the input and output (I/O) devices and load the OPERATING SYSTEM from a disk, cassette, or built-in READ ONLY MEMORY (ROM)
1 Referring to a self-generating or self-sustaining process; specifically, the operation of liquid-propellant rocket engines in which, during main-stage operation, the gas generator is fed by the main propellants pumped by the turbopump, and the turbopump in turn is driven by hot gases from the gas generator system
A bootstrap is a small program which is contained in your boot sector This program may "boot" your computer by loading the operating system, or it may simply display the message which you see when you attempt to boot off a non system disk
This is the program that does the job of loading the OS kernel and any associated modules that the kernel may need to start setting up an execution environment A bootloader is usually stored in ROM In the case of the IA-32 there are a number of bootstraps, the first resides in the BIOS and then that reads in another from the MBR of a disk which normally contains another bootstrap Examples of a bootstrap are GRUB, LILO, LOADLIN, MILO, etc
The technique of random resampling from a given sample (usually with replacement, but sometimes without replacement using an extensive replication of the given sample to resample from) and computation of the statistic of interest after each resampling Because the given sample should be shaped approximately like the unknown population, the bootstrap-produced distribution of the statistic of interest (as given by its relative frequency histogram) should be a good estimate of the unknown theoretical distribution of the statistic of interest Many nonparametric estimation and hypothesis testing procedures can be constructed using bootstrapping to estimate the unknown distribution of the statistic of interest
a method for assessing the statistical significance the positions of branches in a phylogenetic tree that is inferred by a pairwise method (e g Neighbor-Joining or UPGMA) A bootstrap starts with a set of sequences in which every possible sequence pair has been aligned For each aligned pair, it samples scores from random positions in the alignment, adding the scores This is repeated until the pseudo-alignment is the same length as the real alignment When all the pairs have been sampled, it converts the scores to distances and computes a tree This whole process is repeated many times and the frequency with which particular tree features are observed is taken as a measure of the probability that the feature is correct See Bootstrap in Detail for more
A short program, often written in assembler, which gains control when the machine is first powered on The bootstrap sets up an environment that will allow the Kernel to continue to boot Symbian OS (e g setting up memory, I/O devices and creating virtual memory space)
The bootstrap program can be used to start the computer, and in doing so, clear the memory, set up devices, and load the operating system from input/output internal or external memory
