cross-validation method

基本解释

Lastly, the validity of the model is also testified by the cross-validation method.
最后，利用交叉检验法验证该模型的正确性。
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.
这种新策略用于确定主成分数的交叉验证时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.
采用基于平行网格搜索的交叉验证法选择模型参数，避免了参数选择的盲目性、随意性，提高了预测精度。
