glvi 0.1.7

Local variable importance from a global model

glvi

glvi is a Python module for machine learning built on top of Scikit-learn and is distributed under the MIT license.

glvi was developed by Mr. Li for evaluating variable importance heterogeneity through a global model built on a large time-space scope.

glvi 0.1.4 was not supporting Python 2.7 and Python 3.4. glvi 0.1.4 and later require Python 3.5 or newer.

glvi requires:

• Python (>= 3.5)
• NumPy (>= 1.11.0)
• SciPy (>= 0.17.0)
• Scikit-learn (>= 0.21.0) User installation

If you already have a working installation of numpy, scipy, pandas and scikit-learn, the easiest way to install glvi is using ``pip``   ::
	
	pip install -U glvi

User guide

Compute local variable importance based on decrease in node impurity ::

from glvi import todi
r_t = todi.lovim(500, max_features=0.3, n_jobs=-1)
r_t.fit(train_x, train_y)
local_variable_importance = r_t.compute_feature_importance(X,Y,partition_feature = partition_feature, norm=True,n_jobs=-1)

or compute local variable importance based on decrease in accuracy ::

from glvi import meda
r_m = meda.lovim(500, max_features=0.3, n_jobs=-1)
r_m.fit(train_x, train_y_
local_variable_importance = r_m.compute_feature_importance(X,Y,partition_feature = partition_feature, norm=True,n_jobs=-1)
