  abstract =     "This work presents a method to incorporate standard
                 neuro-fuzzy learning for Takagi-Sugeno fuzzy systems
                 that evolve under a grammar driven genetic programming
                 (GP) framework. This is made possible by introducing
                 heteroglossia in the functional GP nodes, enabling them
                 to switch behaviour according to the selected learning
                 stage. A context-free grammar supports the expression
                 of arbitrarily sized and composed fuzzy systems and
                 guides the evolution. Recursive least squares and
                 backpropagation gradient descent algorithms are used as
                 local search methods. A second generation memetic
                 approach combines the genetic programming with the
                 local search procedures. Based on our experimental
                 results, a discussion is included regarding the
                 competitiveness of the proposed methodology and its
                 properties. The contributions of the paper are: (i)
                 introduction of an approach which enables the
                 application of local search learning for intelligent
                 systems evolved by genetic programming, (ii)
                 presentation of a model for memetic learning of
                 Takagi-Sugeno fuzzy systems, (iii) experimental results
                 evaluating model variants and comparison with
                 state-of-the-art models in benchmarking and real-world
                 problems, (iv) application of the proposed model in
                 control.",
