Added

• Counterfactual Explainers (7 methods):

  • COMTE: Counterfactual Multivariate Time-series Explanations using greedy
    channel substitution (Ates et al., 2021)
  • NativeGuide: Instance-based counterfactual explanations using nearest
    unlike neighbor guidance (Delaney et al., 2021)
  • TSEvo: Multi-objective evolutionary optimization using NSGA-II with
    three mutation strategies (Hollig et al., 2022)
  • Glacier: Gradient-based optimization with guided locally constrained
    proximity (Wang et al., 2024)
    constraints (Wang et al., 2021)
  • SETS: Shapelet-based counterfactual explanations using shapelet
    transformation (Bahri et al., 2022)
