部分因子 meaning in English

syngenote

An ffds " design about 6 system variables was conducted with 128 subjects in the second experiment . result was examined using hierarchical regression
该实验使用部分因子设计的实验设计方法，通过分层回归检验了六个系统变量及其二阶交互作用对目击辨认表现的影响。
Its basic principle is to regard selecting or do not selecting a feature as a two - level independent factor ; the parameters of svm as continuous noise factors ; the accuracy of the svm model as the dependent variable ; to employ a fractional factorial experiment design to form the experiment which combines the two - level factors and the noise factors ; after the experiment is finished , to analyze the effect of each factor to determine the effective independent factor combination , namely the best feature combination for the svm model
其基本原?为：将一个输入变?的选取与否视为一个二水准的实验因子；将一个? ?视为一个?续的噪音因子；将模型的准确?视为因变? ； ?用部分因子实验设计得到实验因子与噪音因子的组合；实验完毕后，进?因子的效果分析，以决定最佳的实验因子组合，即最佳的输入变?组合。
