View class distribution¶

The class distribution chart shows the number of samples per class by one of the sources—user or the Prediction tool. This allows detecting the unbalanced class distributions that may cause problems in classification models. The class distribution chart for other sources is available in the train and test centers.

1. In the label center, on the top toolbar, click the charts button.

   

2. On the right, in the Chart type field, select Class distribution.

3. In Labels by, select the source whose labels will be displayed in the chart.

4. Once you have built the class distribution chart, you can do the following:

   • To view the number and percentage of samples labeled with a certain class, hover over the respective bar.

     

   • To filter the samples by class, click the bar next to the necessary class. To display all the samples, click the same bar again.

   • To export the chart as a CSV table, click Export class distribution as CSV.
