class gaitmap_challenges.stride_segmentation.egait_segmentation_validation_2014_original_label.Challenge(dataset: Optional[Union[str, Path, EgaitSegmentationValidation2014]], cv_iterator: Optional[Union[int, BaseCrossValidator, Iterator]] = StratifiedKFold(n_splits=5, random_state=None, shuffle=False), cv_params: Optional[Dict] = None)[source]#

The EgaitSegmentation Validation Challenge using the original labels.

This challenge is identical to Challenge, with the exception that use_original_labels is set to True by default. This means that the original labels are used for the reference stride list.

Parameters:
dataset

A instance of EgaitSegmentationValidation2014 or a path to a directory containing the dataset.

cv_iterator

A cross-validation iterator or the number of folds to use.

cv_params

Additional parameters to pass to the tpcp cross-validation function.

Other Parameters:
match_tolerance_s

(Class Constant) The tolerance in seconds that is allowed between the calculated stride borders and the reference stride borders.

use_original_labels

(Class Constant) If True, the original stride labels are used for the reference stride list. The original labels only contain straight strides. If False, the new labels are used for the reference stride list. The new labels contain all strides including turns and stairs.

Attributes:
cv_results_

The results of the cross-validation. This can be passed directly to the pandas DataFrame constructor to get a dataframe with the results.

Notes

Version History:

  • 1.0.0: Original Version, which had a major bug, that the scorer was still using the new labels.

  • 2.0.0 (2023-09-19): Fixed the bug, that the scorer was still using the new labels.
