Class distribution

The class distribution chart shows the amount of samples per class by one of the sources—model or ground truth. 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 label and training centers.

Note

The chart takes into account the filters you have applied. However, if you apply a filter when the chart is already open, the filter isn't considered. To refresh the chart, click Clear in the upper-right corner of the Chart setup panel, and then set up the chart again.
