Fuzzy interpolative reasoning is a very important research topic for sparse fuzzy rule-based systems. In this thesis, we propose two new adaptive fuzzy interpolative reasoning methods for sparse fuzzy rule-based systems based on polygonal fuzzy sets and interval type-2 fuzzy sets, respectively. In the first method of our thesis, we propose a new adaptive fuzzy interpolative reasoning method based on contradiction measures between polygonal fuzzy sets and novel move and transformation techniques. The proposed adaptive fuzzy interpolative reasoning method performs fuzzy interpolative reasoning using the multiple fuzzy rules with multiple antecedent variables fuzzy interpolative reasoning scheme and solves the contradictions after the fuzzy interpolative reasoning processes based on contradiction measures between polygonal fuzzy sets. The experimental results show that the proposed adaptive fuzzy interpolative reasoning method outperforms the existing methods for fuzzy interpolative reasoning in sparse fuzzy rule-based systems. In the second method of our thesis, we propose a new adaptive weighted fuzzy interpolative reasoning method for sparse fuzzy rule-based systems based on representative values and similarity measures of interval type-2 fuzzy sets. The experimental results show that the proposed adaptive weighted fuzzy interpolative reasoning method can overcome the drawbacks of the existing adaptive fuzzy interpolative reasoning methods for sparse fuzzy rule-based systems.
