When we make the rotation, we can check if that operation made our tree imbalanced and if so, we can do ... Witryna13 lis 2024 · Part 3.5: Rotations. Now that we’ve seen four different cases of an imbalanced tree, let’s see how to fix each of them using rotations. Note that the binary search tree property is preserved ...
Witryna30 lip 2024 · ROC Threshold Moving for Imbalanced Classification. As alluded to above, using the default probability threshold of 0.5 to predict class labels in case of imbalanced classification problems will likely lead to poor model performance. Luckily, it is pretty straightforward to determine the optimal probability threshold in the case of ROC curves.
