Python RandomSpike Examples

Example #1

 def test_with_spikes(self):
     transform = RandomSpike()
     transformed = transform(self.sample_subject)
     self.assertTensorNotEqual(
         self.sample_subject.t1.data,
         transformed.t1.data,
     )

Example #2

 def test_with_zero_intensity(self):
     transform = RandomSpike(intensity=0)
     transformed = transform(self.sample_subject)
     self.assertTensorAlmostEqual(
         self.sample_subject.t1.data,
         transformed.t1.data,
     )

Example #3

 def test_wrong_intensity_type(self):
     with self.assertRaises(ValueError):
         RandomSpike(intensity='wrong')

Example #4

 def test_wrong_num_spikes_type(self):
     with self.assertRaises(ValueError):
         RandomSpike(num_spikes='wrong')

Example #5

 def test_not_integer_num_spikes(self):
     with self.assertRaises(ValueError):
         RandomSpike(num_spikes=(0.7, 4))

Example #6
