#### Get Predictions #### Get Predictions
After training, we can use the output model to get the prediction of the test data: After training, we can use the output model to get the prediction of the test data:
``` ```
../../xgboost mushroom.conf task=pred model_in=0003.model ../../xgboost mushroom.conf task=pred model_in=0002.model
``` ```
For binary classification, the output predictions are probability confidence scores in [0,1], corresponds to the probability of the label to be positive.

#### Dump Model #### Dump Model
This is a preliminary feature, so far only tree model support text dump. XGBoost can display the tree models in text files and we can scan the model in an easy way: This is a preliminary feature, so far only tree model support text dump.

In this demo, the tree boosters obtained will be printed in dump.raw.txt and dump.nice.txt, and the latter one is easier to understand because of usage of feature mapping featmap.txt In this demo, the tree boosters obtained will be printed in dump.raw.txt and dump.nice.txt, and the latter one is easier to understand because of usage of feature mapping featmap.txt
