Higher-Order TSK Fuzzy Models
This research introduces a novel Takagi-Sugeno-Kang (TSK) fuzzy model with generalized rule consequents, moving beyond traditional linear forms. By integrating model complexity into the optimization scheme, the system automatically determines the optimal functional form (linear, quadratic, or higher-order) for each rule. This enhances the model's degrees of freedom and predictive power without pre-defining its structure, yielding robust and adaptive AI for complex time series.
Adaptive Evolution & Bayesian Search
Two advanced optimization techniques were explored for training the fuzzy models: an adaptive Differential Evolution (DE) algorithm with dual populations and self-adjusting parameters, and a Bayesian Optimization (BO) approach utilizing a Gaussian process surrogate model. While both achieved high accuracy, BO significantly reduced training time by efficiently exploring the parameter space and minimizing expensive function evaluations, making it highly suitable for large-scale enterprise deployments.
VMD & Feature Selection
To address the highly stochastic nature of wind speed, the methodology incorporates Variational Mode Decomposition (VMD), breaking down the raw data into multiple intrinsic mode functions. Each mode is then predicted by an individual optimized fuzzy model, enhancing accuracy and robustness to noise. A sequential wrapper-based algorithm systematically selects the most effective lagged features for each sub-model, ensuring an optimally configured input space and minimizing computational complexity.

Case Study: Precision Wind Speed Prediction for Energy Grids
Applied to a real-world wind speed dataset from the National Observatory of Athens, Greece, this methodology demonstrates robust performance critical for renewable energy management. Accurate wind speed forecasts enable better grid stability, optimized turbine operations, and improved energy trading strategies. The combination of VMD with optimized higher-order TSK fuzzy models provides superior predictive power compared to existing benchmarks, addressing the inherent stochasticity of wind.
Our Bayesian-optimized approach yields highly accurate predictions with significantly reduced training times, making it an ideal candidate for real-time operational environments where both speed and precision are paramount for sustainable energy initiatives.
