Implementation of Decision Tree Algorithm using Gini Index

To install python packages for running code, run the following command:

• pip install -r requirements.txt

Running the following command to preprocess dataset:\

• For train dataset run python3 preprocessing.py --input_file adult.train --output_file train.csv
• For test dataset run python3 preprocessing.py --input_file adult.test --output_file test.csv

To run decision tree algorithm, run the following command:
python3 dtbuild.py --train_file <path/to/training_data> --model_file <path/to/save_model> --min_freq <min_freq>

To get result for test set, using this command:
python3 dtclassify.py --model_file <path/to/model_file> --test_file <path/to/test/file> --predictions <name of prediction file>

To evaluate your result on test set, using this command:
python3 dtevaluate --pred <path/to/prediction_file>
