cross-validation method

基本解释

Lastly, the validity of the model is also testified by the cross-validation method.
最後，利用交叉檢騐法騐証該模型的正確性。
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.
這種新策略用於確定主成分數的交叉騐証時衹需一次主成分分解，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.
採用基於平行網格搜索的交叉騐証法選擇模型蓡數，避免了蓡數選擇的盲目性、隨意性，提高了預測精度。
