# 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]

An [example](https://wiki.g15e.com/pages/Example%20(machine%20learning.txt)) that contains [features](https://wiki.g15e.com/pages/Feature%20(machine%20learning.txt)) but no [label](https://wiki.g15e.com/pages/Label%20(machine%20learning.txt)). 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](https://wiki.g15e.com/pages/Supervised%20learning.txt), models train on labeled examples and make predictions on unlabeled example.

In [semi-supervised learning](https://wiki.g15e.com/pages/Semi-supervised%20learning.txt) and <unsupervised learning>, unlabeled examples are used during [training](https://wiki.g15e.com/pages/Training%20(machine%20learning.txt)).
