This paper proposes an aim-object-based asymmetric neuro-fuzzy system that is different from conventional models in two ways. First, this system has an asymmetric structure with different numbers of neurons in the premise and consequent layers. Secondly, with the assistance of the sphere complex fuzzy set, depending on the application, our model can alter the number of outputs. In addition, a hybrid learning algorithm combining the whale optimization algorithm and the recursive least-square estimator is proposed to optimize the proposed model. The results of the experiment show that the proposed model can simultaneously predict multiple targets with fewer parameters and maintain a performance level similar to that of the conventional neuro-fuzzy system.
