Dependencies

To install dependencies, run the command below. pip install -r requirements.txt

Be aware that I use python as the python command. This code requires Python 3 for some systems, python will be located at the python3 command.

Run the code

To run the code, you must exrecute python ./main.py from the root directory. Running the code will not give all question solutions.

To change the dataset, you must change the condtion on line 194 to select the database you wish to evaluate.

When working with Dbig.txt, you mus also uncomment the big_dataset_logic and comment out the normal_dataset_logic. To observe the sklearn tree, the process is the same except uncommenting the sklearn_tree_analysis. A note about the sklearn question, the datasets are built with uniform random sampling on each script run, thus the results will slightly differ per run.

When validating bad_dataset.txt you must change line 110 from t = DecisionTree(dataset[key],name=key,force_choice=False,choice_ind=2) to t = DecisionTree(dataset[key],name=key,force_choice=True,choice_ind=2).

When testing question 4, you must execute the command python ./lagrange_interpolation.py
