Learn rule lists from data for classification, regression or subgroup discovery
Project description
MDL Rule Lists for prediction and subgroup discovery.
This repository contains the code for using rule lists for univariate or multivariate classification or regression and its equivalents in Data Mining and Subgroup Discovery. These models use the Minimum Description Length (MDL) principle as optimality criteria.
Dependencies
This project was written for Python 3.7. All required packages from PyPI are specified in the requirements.txt
.
NOTE: This list of packages includes the gmpy2
package.
Installation
The latest release can be installed using pip:
pip install rulelist
If you run into issues regarding the gmpy2
package mentioned above, please refer to their documentation for help.
For the current version, you can clone the repository and install the dependencies locally:
git clone https://github.com/HMProenca/RuleList.git
cd RuleList
pip install -r requirements.txt
Example of usage for prediction:
import pandas as pd
from rulelist import RuleList
from sklearn import datasets
from sklearn.model_selection import train_test_split
task = 'prediction'
target_model = 'categorical'
data = datasets.load_breast_cancer()
Y = pd.Series(data.target)
X = pd.DataFrame(data.data)
X_train, X_test, y_train, y_test = train_test_split(X, Y, test_size = 0.3)
model = RuleList(task = task, target_model = target_model)
model.fit(X_train, y_train)
y_pred = model.predict(X_test)
from sklearn.metrics import accuracy_score
accuracy_score(y_test.values,y_pred)
print(model)
Example of usage for subgroup discovery:
import pandas as pd
from rulelist.rulelist import RuleList
from sklearn import datasets
task = 'discovery'
target_model = 'gaussian'
data = datasets.load_boston()
y = pd.Series(data.target)
X = pd.DataFrame(data.data)
model = RuleList(task = task, target_model = target_model)
model.fit(X, y)
print(model)
