1. Modify the training script (i.e. master.py) to point to your data directory.
2. Run the training script (i.e. master.py) to learn best parameters for your features. The applyCrossValidation variable must be marked True (applyCrossValidation=True) in order to learn the parameters.
3. After learning the relevant parameters, run the training script with these parameters to train and evaluate the PBT or IBT model. The applyCrossValidation variable must be marked False (applyCrossValidation=False) in order to learn and evaluate the correct model.

Pretrained models and related parameters are shared under models/ directory. NUM_HIDDEN and stopIter parameters for these models are as follows:

• IBT-AwA: NUM_HIDDEN=100, stopIter=26000
• PBT-AwA: NUM_HIDDEN=400, stopIter=6000
• IBT-aPaY: NUM_HIDDEN=100, stopIter=15800
• PBT-aPaY: NUM_HIDDEN=100, stopIter=6000
