From: Predicting reactive stepping in response to perturbations by using a classification approach
Performance on the test data set using the original full feature set and kinematics feature set, and the three reduced feature sets that followed from recursive feature elimination. SLU indicates step leg unloading, TO indicates toe-off, tSLU−n and tTO−n indicate the nth time step before step leg unloading and toe-off respectively. Predictions were made using various observation time windows: from the start of the perturbation until each prediction time step
