WebLike most machine learning algorithms, Decision Trees include two distinct types of model parameters: learnable and non-learnable. Learnable parameters are calculated during training on a given dataset, for a model instance. The model is able to learn the optimal values for these parameters are on its own. In essence, it is this ability that puts the … WebSetting criterion="poisson" might be a good choice if your target is a count or a frequency (count per some unit). In any case, \(y >= 0\) is a necessary condition to use this criterion. Note that it fits much slower than the MSE criterion. Mean Absolute Error:
