The training data varies depending on whether we are using Supervised Learning or Unsupervised Learning Algorithms. For Unsupervised learning, the training data contains unlabeled data points, i.e., inputs are not tagged with the corresponding outputs.Models are required to find the patterns from the given training datasets in order to make predictions. When modeling, it is important to clean the data sample to ensure that the observations best represent the problem. Sometimes a dataset can contain extreme values that are outside the range of what is expected and unlike the other data. These are called outliers and often machine learning modeling and model skill in general can be improved by . Test Dataset: The sample of data used to provide an unbiased evaluation of a final model fit on the training dataset. .
