+1. **Validate input data**: Process each data type, e.g. encoding categorical data, so that Auto-Pytorch can handled
 2. **Create dataset**: Create a dataset that can be handled in this API including cross validation splits
 3. **Evaluate baselines**: Train each algorithm in the predefined pool with a fixed hyperparameter configuration and dummy model from `sklearn.dummy` that represents the worst possible performance
