Artificial Intelligence BoostingBootstrapping

Bootstrap aggregating (bagging) is a machine learning ensemble meta-algorithm to improve machine learning of classification and regression models in terms of stability and classification accuracy.

 


Bootstrap Computation using R
By Lyra Filiola
Bootstrap is a computational method based on computer. Development of computer technology makes bootstrapping data becomes much easier than ever.

Bootstrap
The so called "bootstrap" method generates, for any quantity defined on a on a (unknown) probability distribution :
an estimate of this quantity,
as well as a measure of the uncertainty regarding this estimation.

Bootstrap Plot
Purpose:
Estimate uncertainty
The bootstrap (Efron and Gong) plot is used to estimate the uncertainty of a statistic.

Bootstrapping A technique for simulating new data sets, to assess the robustness of a model or to produce a set of likely models.

Bootstrapping - this technique (Efron, 1979) samples a data set with replacement (i.e. a single case may be randomly sampled several times into the bootstrap set). The bootstrap can be applied any number of times, for increased accuracy.

Vygotskian theory posits that children need to "learn to learn" - by mastering a set of mental tools which bootstrap their mental abilities, the same way that physical tools can extend physical abilities.

Q. Might an AI system be able to bootstrap itself to higher and higher level intelligence by thinking about AI?
A. I think yes, but we aren't yet at a level of AI at which this process can begin.
Q. What about chess?

scientists, Ray Kurzweil and Hans Moravec, came out independently with serious books that proclaimed that in the coming century, our own computational technology, marching to the exponential drum of Moore's Law and more general laws of bootstrapping, ...

Method: for i = 1 to k do // create k models: create bootstrap sample, Di , by sampling D with replacement; use Di to derive a model, Mi ; endfor To use the composite model on a tuple, ...

there is actually very little code (~1000 lines, including WAV file processing) since i relied mostly on the pronouncing dictionary and voice database to bootstrap the application.

This notion of "bootstrapping"-that is, applying a problem-solving system to the task of improving some of its own methods-is old and famil1ar, but in [15] we find perhaps the first specific proposal about how such an advance might be realized.
