| 释义 | bootstrapping noun[ U ] uk /ˈbuːtˌstræpɪŋ/us FINANCE the process of starting and developing a business by using a lot of effort and no investment by outside owners: His success follows the central themes: bootstrapping, ambition, and vision. Examples of bootstrappingbootstrapping Bootstrapping analysis with 1000 replicates was conducted to evaluate the statistical significance of each branching point. When the bootstrapping process finished, we had a ranked list of hypothesized words for each of the eleven semantic classes. Bootstrapping allows the estimation of the sampling distribution of virtually any statistic, merely by re-sampling and re-estimating it multiple times. Bootstrapping knowledge representations: from entailment meshes via semantic nets to learning webs. The 95% confidence intervals for mean values of this index were computed by bootstrapping. Ninety-five per cent confidence intervals are derived by parametric bootstrapping of the data (see text). Hypothesis tests and confidence intervals on vector coefficients were determined by bootstrapping over clone means ; this test assumes that family means were calculated without error. However, due to the non-independence of heterozygous genotypes in diallel crosses bootstrapping cannot be performed. The idea of indirect downward bootstrapping is probably applicable to many additional bootstrapping cases. This bootstrapping mechanism dynamically grows the seed word list so that each iteration produces a larger category context. The seed segmenter is improved iteratively by applying a bootstrapping scheme to a very large unsegmented corpus. The bootstrapping algorithm found many new members of each class, although the quality of the ranked lists varied depending on the semantic class. The same topology was found by bootstrapping with high bootstrap values (data not shown). The most confident predictions are added to the lexicon automatically and the process repeats in a bootstrapping fashion. If, say, phonological and semantic bootstrapping occur in ontogenesis, they rely on producing formally consistent meanings.
