示例1: test_graph_crf_loss_augment
# 需要导入模块: from pystruct.models import GraphCRF [as 别名]
# 或者: from pystruct.models.GraphCRF import initialize [as 别名]

y = y_1
crf = GraphCRF()
crf.initialize([x], [y])

# check that y_hat fulfills energy + loss condition
assert_almost_equal(np.dot(w, crf.joint_feature(x, y_hat)) + crf.loss(y, y_hat),
-energy)示例2: test_initialize
