On Explainable Fuzzy Recommenders and their Performance Evaluation

Abstract: This paper presents a novel approach to the design of explainable recommender systems. It is based on the Wang–Mendel algorithm of fuzzy rule generation. A method for the learning and reduction of the fuzzy recommender is proposed along with feature encoding. Three criteria, including the Akaike information criterion, are used for evaluating an optimal balance between recommender accuracy and interpretability. Simulation results verify the effectiveness of the presented recommender system and illustrate its pe… Show more

“…The existing literature generally classifies the XAI taxonomy as follows [ [155] , [156] , [157] ]: Stage : ante-hoc [ 158 , 159 ] and post-hoc, where post-hoc methods are further classified into model-agnostic and model-specific. Scope : local [ 160 , 161 ] and global [ 162 , 163 ]. Output format : numeric [ 164 ], visualization [ 165 ], etc.…”

“…De et al proposed the existing TREPAN decision tree as a surrogate model with an FFNN to generate rules depicting the flow of information within the neural network [89]. Rutkowski et al used the Wang-Mendal (WM) algorithm to generate fuzzy rules to support recommendations with explanations [157]. A novel neuro-fuzzy system, ALMMo-0*, was proposed by Soares et al [116].…”
