[en] This paper introduces the Inverted Hierarchical Neuro-Fuzzy BSP System (HNFB 1), a new neuro-fuzzy model that has been specifically created for record classification and rule extraction in databases. The HNFB 1 is based on the Hierarchical Neuro-Fuzzy Binary Space Partitioning Model (HNFB), which embodies a recursive partitioning of the input space, is able to automatically generate its own structure, and allows a greater number of inputs. The new HNFB 1 allows the extraction of knowledge in the form of interpretable fuzzy rules expressed by the following: If is and is , then input pattern belongs to class . For the process of rule extraction in the HNFB 1 model, two fuzzy evaluation measures were defined: 1) fuzzy accuracy and 2) fuzzy coverage. The HNFB 1 has been evaluated with different benchmark databases for the classification task: Iris Dataset,Wine Data, Pima Indians Diabetes Database, Bupa Liver Disorders, and Heart Disease. When compared with several other pattern classification models and algorithms, the HNFB 1 model has shown similar or better classification performance. Nevertheless, its performance in terms of processing time is remarkable. The HNFB 1 converged in less than one minute for all the databases described in the case study.
