SpletNested cross-validation (CV) is often used to train a model in which hyperparameters also need to be optimized. Nested CV estimates the generalization error of the underlying model and its (hyper)parameter search. Choosing the parameters that maximize non-nested CV biases the model to the dataset, yielding an overly-optimistic score. SpletSVM의 특징 - 기존의 지도학습 모형과 같이 예측 부분에서 활용될 수 있으며 기계학습 부분에서 다른 모델에 비해 예측률이 높다고 알려져 있다. - 넓은 형태의 데이터셋(많은 …
