Python Layer.set_biases Examples

Example #1

File: layer_tests.py Project: X-rayLaser/DeepNetLib

    def test_with_single_hidden_layer(self):
        layer = Layer(size=3,
                      prev_size=2,
                      activation=activation_functions.Sigmoid)
        biases = [-2, 0.5, 9]
        layer.set_biases(biases=np.array(biases, float))

        self.assertEqual(layer.biases().tolist(), [-2, 0.5, 9])
