Evaluation Metric | Eval Metric | Determines which evaluation metric to use:\n 1) Default\n 2) Error\n 3) Log Loss\n 4) None | Integer |
Learning Rate | Learning Rate | The shrinkage rate for trees, used to prevent over-fitting. Valid range is [0,1]. | Number |
Sigmoid Parameter | Sigmoid | Determines the steepness of the sigmoid function | Number |
Use SoftMax | Use Softmax | Determines whether to use the SoftMax loss function. The SoftMax function is a generalization of the logistic function to multiple dimensions. | Boolean |
Max Bins Per Feature | Max Bins | The maximum number of bins that feature values will be bucketed in. A small number of bins may reduce training accuracy but may increase general power (deal with over-fitting). | Integer |
