학습 데이터

The subset of the dataset used to train a model. Traditionally, examples in the dataset are divided into the following three distinct subsets:¹

• a training set
• a Validation set
• a Test set

Ideally, each example in the dataset should belong to only one of the preceding subsets. For example, a single example shouldn’t belong to both the training set and the validation set.¹
