If you are making a … WitrynaWhen a dataset's distribution of classes is uneven, it is said to have imbalanced data. In other words, compared to the other classes, one class has significantly more or fewer samples. This can be a problem because most machine learning algorithms are made to function best with balanced data, which means that there are roughly equal numbers …
