 If we don't randomly withhold some of the data from ourselves and then evaluate our model against that withheld data, we will inevitably overfit the model and lose our general preditivity.
 
 ### Step 3: Machine Learning Models (`src/decision_tree.py`)

+Step 3 of the pipeline is to supply data to a machine learning algorithm (or several) and made predictions on the data asked of us from `test.csv`, as provided by the kaggle competiton. See the [algorithms section](https://github.com/emilyagras/kaggle-favorita/blob/master/README.md#algorithms) below for more details on what we've implemented.
 
 ## Algorithms
 We implement one machine learning model for the time being, which creates a model based on the training data, rates its own accuracy using the validation data, and creates predictions, ready to be submit to kaggle.com from the `train.csv` file that was provided through the competiton.
