Author:

Alberto M. Esmoris Pena

Receptive field test that checks the indexing matrix, the centroids, and the propagation work as expected for some use cases.

__init__()

Basic configuration for any VL3D test.

Parameters:

name (str) – Test name

run()

Run receptive field test.

Returns:

True if ReceptiveField works as expected for the test cases, False otherwise.

Return type:

bool

test_grid_receptive_fields()

Run grid receptive field tests.

Returns:

True if RepcetiveFieldGS works as expected for the test cases, False otherwise.

Return type:

bool

test_fps_receptive_fields()

Run FPS receptive field tests.

Returns:

True if ReceptiveFieldFPS works as expected for the test cases, False otherwise.

static test_grid_receptive_field(bounding_radii, cell_size, center_point, input_points, values_to_propagate, expected_num_cells, expected_centroid_nointerp, expected_centroid_interp, expected_propagated_values, eps=1e-06)

Build a grid receptive field with the input points and propagate the given values. Then, the results are compared with the expected outputs to validate the implementation.

Parameters:

  • bounding_radii – The bounding radii to build the receptive field.

  • cell_size (np.ndarray) – The cell size to build the receptive field.

  • center_point (np.ndarray) – The center point for the receptive field.

  • input_points – The input points to build the receptive field.

  • values_to_propagate (np.ndarray) – The values to propagate through the receptive field.

  • expected_num_cells (int) – The expected number of cells composing the receptive field.

  • expected_centroid_nointerp (np.ndarray) – The expected centroids (without interpolation).

  • expected_centroid_interp (np.ndarray) – The expected centroids (with interpolation).

  • expected_propagated_values (np.ndarray) – The expected propagated values.

  • eps (float) – The decimal tolerance for numerical validation.

Returns:

True if the receptive field behaves as expected, False otherwise.

static test_fps_receptive_field(X, F, y, rfArgs, eps)

Build a FPS receptive field with the input points and check that the features and labels are encoded as expected.

Parameters:

  • X (np.ndarray) – The structure space for the test.

  • F (np.ndarray) – The feature space for the test.

  • y (np.ndarray) – The point-wise labels for the test.

  • rfArgs (dict) – The key-word arguments to build the FPS receptive field. See ReceptiveFieldFPS.

  • eps (float) – The decimal tolerance threshold.
