Fuzzy Relation-Based Neural Networks and Their Hybrid Identification
Bibliographic record
Abstract
In this paper, we develop a comprehensive identification scheme for fuzzy relation-based neural networks (FRNNs). The proposed hybrid development approach combines the optimization technology of genetic algorithms (GAs) and an improved complex method introduced in the previous studies on fuzzy modeling. The structure of the FRNNs revolves around a collection of fuzzy rules and involves two types of fuzzy inference schemes. The taxonomy of these schemes relates to the format of the conclusion part of these rules (being either constants or linear functions). The optimization of the network deals with a number of essential parameters as well as the underlying learning mechanisms (e.g., apexes of membership functions, learning rates, and momentum coefficients). The hybrid identification approach helps achieve global optimization (when using GAs) and assure local convergence (that results from the use of the improved complex method). During the identification process, we are guided by a weighted objective function (performance index) in which a weighting factor is introduced to achieve a sound balance between approximation and generalization capabilities of the resulting model. The proposed identification method is applied to nonlinear processes (data) such as gas furnace process data and emission process data form a gas turbine power plant. The obtained experimental results show that the proposed networks exhibit high accuracy and generalization capabilities.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
