Model Specifications modify a model’s behavior and access to server resources.
simRegression parameters guide the model training process by dictating the number and size of decision trees to be constructed, as well as other aspects of the learning procedure. [Therefore, it is highly recommended to use a grid to select the appropriate parameters. <- We should add this once we support grids for Regression.]
Iterations | Number of gradient boosting algorithm iterations/trees. More iterations can improve accuracy but increase overfitting risk. |
Max Depth |
Maximum tree depth. Deeper trees capture more complex patterns but may overfit. |
ETA | Learning rate shrinkage to prevent overfitting. Smaller ETA values slow down learning and help in avoiding overfitting. |
Col Sample by Tree | Feature sub-sample ratio per tree. Lower ratios increase diversity and prevent overfitting. |
Regression Objective |
Loss function used for training. It should match the regression problem's specifics. The allowed values are:
