+.. py:function:: load_default_grid()
+ :noindex:
+ :module: gensvm.gridsearch
+
+ Load the default parameter grid for GenSVM
+
+ This is the parameter grid used in the GenSVM paper to run the grid search
+ experiments. It uses a large grid for the ``lmd`` regularization parameter
+ and converges with a stopping criterion of ``1e-8``. This is a relatively
+ small stopping criterion and in practice good classification results can be
+ obtained by using a larger stopping criterion.
+
+ The function returns the following grid::
+
+ pg = {
+ 'lmd': [pow(2, x) for x in range(-18, 19, 2)],
+ 'kappa': [-0.9, 0.5, 5.0],
+ 'p': [1.0, 1.5, 2.0],
+ 'weights': ['unit', 'group'],
+ 'epsilon': [1e-8],
+ 'kernel': ['linear']
+ }
+
+ :returns: **pg** -- Mapping from parameters to lists of values for those parameters. To be
+ used as input for the :class:`.GenSVMGridSearchCV` class.
+ :rtype: dict
