Role of validation for neural network (deep learning) - validation 역할

Why do we need validation (validation이 필요한 이유)? In order to estimate how well your model has been trained (that is dependent upon the size of your data, the value you would like to predict, input etc) and to estimate model properties (mean error for numeric predictors, classification errors for classifiers, recall and precision for IR-models etc.) - 모델이 학습이 잘 되었는지 측정하기 위해 A set of examples used ..
