Unlabeled example
An example that contains features but no label. For example, the following table shows three unlabeled examples from a house valuation model, each with three features but no house value:1
| Number of bedrooms | Number of bathrooms | House age |
|---|---|---|
| 3 | 2 | 15 |
| 2 | 1 | 72 |
| 4 | 2 | 34 |
In supervised machine learning, models train on labeled examples and make predictions on unlabeled example.
In semi-supervised learning and unsupervised learning, unlabeled examples are used during training.
