Exemple #1

Fichier : features_dense_longint_modular.py Projet : AlexBinder/shogun

def features_dense_longint_modular (A=matrix):
	a=LongIntFeatures(A)
	# get first feature vector and set it

	a.set_feature_vector(array([1,4,0,0,0,9], dtype=int64), 0)

	# get matrix
	a_out = a.get_feature_matrix()

	assert(all(a_out==A))
	return a_out

Exemple #2

def features_dense_longint_modular(A=matrix):
