示例1: test_drop_empty_samples_original_unchanged
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import get_labels [as 别名]
def test_drop_empty_samples_original_unchanged(self):
data_list = [[1, 2, np.NAN], [np.NAN, np.NAN, np.NAN], [7, 8, 9]]
label_list = ["a", "b", "c"]
original = DataSet(pd.DataFrame(data_list), labels=label_list)
filtered = original.drop_empty_samples()
filtered.set_column(0, [-1, -1])
filtered.labels[0] = "z"
assert_that(original, equals_dataset(data_list))
assert_that(original.get_labels(), contains(*label_list))示例2: test_slice_features_original_unchanged
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import get_labels [as 别名]
def test_slice_features_original_unchanged(self):
df = pd.DataFrame([[1, 2, 3], [4, 5, 6], [7, 8, 9]],
columns=["weight", "height", "age"])
labels = ["m", "f", "m"]
dataset = DataSet(df, labels=labels)
sliced = dataset.slice_features(["weight", "height"])
# Modify sliced data
sliced.set_column("weight", [0, 0, 0])
sliced.labels[0] = "x"
# Check that it was indeed changed
assert_that(sliced.get_column("weight"), contains(0, 0, 0))
assert_that(sliced.get_labels(), contains("x", "f", "m"))
# Verify it was not changed in the original dataset
assert_that(dataset.get_column("weight"), contains(1, 4, 7))
assert_that(dataset.get_labels(), contains(*labels))示例3: test_combine_labels
# 需要导入模块: from pml.data.model import DataSet [as 别名]
# 或者: from pml.data.model.DataSet import get_labels [as 别名]
def test_combine_labels(self):
dataset = DataSet([[1, 2], [3, 4], [5, 6]],
labels=pd.Series(["cat", "crow", "pidgeon"]))
dataset.combine_labels(["crow", "pidgeon"], "bird")
labels = dataset.get_labels()
assert_that(labels, equals_series({0: "cat", 1: "bird", 2: "bird"}))
