4.2 Dataset Size

By default, BigML uses all the data you have in your source. However, when you deal with big datasets, you can accelerate exploration of your data by setting aside a subset of your source, and build your dataset with only a small part of your data. Select the percentage you want to use to create your dataset by moving the highlighted size slider in Figure 4.2 . In this example we are using the 10% of the source imported into BigML.

This option is not available when your source contains images. However, you can always use sampling (section 7.2 ) after the dataset is created.
