Algorithm 3 XAI Integration in Decision-Making for UI

Require: Hybrid feature importance

ϕ_{i}^{Hybrid}

for all

f_{i} \in F

, Decision policy

π

Ensure: Adjusted decision policy

π_{E L}

1:
Input: Hybrid feature importance $ϕ_{i}^{Hybrid}$ , Decision policy $π$
2:
Output: Adjusted decision policy $π_{E L}$
3:
Step 1: Integration of Explainability
4:
Initialize $π_{E L} (s) = π (s)$
5:
for each feature $f_{i} \in F$ do
6:
Update policy $π_{E L} (s) = π_{E L} (s) + λ \cdot ϕ_{i}^{Hybrid} \cdot f_{i} (s)$
7:
end for
8:
Return: Adjusted policy $π_{E L}$
