Performance using features extracted from the walkway. (a) Performance on validation and test sets, where vertical lines indicate standard deviation of the 20 inner CVs. The statistical analysis compares the best-performing experiment (DS1 + SS) with the results achieved in the other conditions, using Paired Samples T-tests or Wilcoxon signed-rank tests with Bonferroni correction, where *p < 0.05, **p < 0.01, and ***p < 0.001 indicate statistical significance. (b) Confusion matrix of the DS1 + SS condition. (c) Feature selection frequency for the DS1 + SS condition
