PyGRF 0.0.9
PyGRF
PyGRF: An improved Python Geographical Random Forest (GRF) model.
Installation:
PyGRF can be installed from PyPI:
$ pip install PyGRF
Example:
Below shows an example on how to fit a PyGRF model and use it to make predictions.
from PyGRF import PyGRF
from sklearn.model_selection import train_test_split
# Split your data into training and test sets
X_train, X_test, y_train, y_test = train_test_split(X, y, random_state=42)
#Create a PyGRF model by specifying hyperparameters
pygrf_example = PyGRF.PyGRFBuilder(n_estimators=60, max_features=1, band_width=39, train_weighted=True, predict_weighted=True, bootstrap=False,
resampled=True, random_state=42)
#Fit the created PyGRF model based on training data and their spatial coordinates
pygrf_example.fit(X_train, y_train, xy_coord)
#Make predictions for testing data using the fitted PyGRF model and you specified local model weight
predict_combined, predict_global, predict_local = pygrf_example.predict(X_test, coords_test, local_weight=0.46)
