cross-validation method

基本解釋

Lastly, the validity of the model is also testified by the cross-validation method.
最后，利用交叉檢驗(yàn)法驗(yàn)證該模型的正確性。
The new strategy is very fast when the number of the principal components is determined by the cross-validation method because only one decomposition is necessary.
這種新策略用于確定主成分?jǐn)?shù)的交叉驗(yàn)證時(shí)只需一次主成分分解，因此速度很快；
The cross-validation method via parallel grid search is used to avoid blindness and randomness in model parameter selection, and the prediction precision is improved.
采用基于平行網(wǎng)格搜索的交叉驗(yàn)證法選擇模型參數(shù)，避免了參數(shù)選擇的盲目性、隨意性，提高了預(yù)測精度。
