Auto Feature Engineering, Make Golden Features in Tabular Dataset

This repository mimics mljar's Golden Features Method.

It has the advantage of being able to automatically proceed with FeatureEnginering.

It working on Tabular Dataset.

Performance

Sample JupyterNotebook

The Boston dataset showed the following performance improvements using the Top10 feature.

[{'Feature': 'NOX_plus_PTRATIO', 'Score': 0.8822110289465535},
 {'Feature': 'RM_divide_B', 'Score': 0.8669953317836949},
 {'Feature': 'TAX_plus_PTRATIO', 'Score': 0.8668896359860812},
 {'Feature': 'RM_divide_RAD', 'Score': 0.8664016362396519},
 {'Feature': 'TAX_divide_B', 'Score': 0.8661958667613189},
 {'Feature': 'B_divide_LSTAT', 'Score': 0.8649016554522404},
 {'Feature': 'RM_multiply_AGE', 'Score': 0.8635321077767777},
 {'Feature': 'CRIM_multiply_PTRATIO', 'Score': 0.8631138222798383},
 {'Feature': 'DIS_multiply_LSTAT', 'Score': 0.8619849012074536},
 {'Feature': 'CRIM_divide_AGE', 'Score': 0.8617352792173447}]
BEFORE MSE: 24.2911194749736
AFTER MSE: 17.55893128587233

Run Python Script

Running it as a script can be a bit slow because it automatically checks if it is a regression task.

python MakeGoldenFeature.py -t reg -l label -i train.csv -o goldenfeatures.json

# -t MLtask
# -l Label Feature Name
# -i input csv
# -o output json
