Hybrid intelligent systems are formed by prudent combinations of intelligent models, such as neural networks, fuzzy models and others, to achieve efficient solutions to real-world problems. The main idea is to take advantage of the main characteristics of the individual models. For example, neural networks are good for learning from training data, while fuzzy logic is good for representing expert knowledge and uncertainty management, and evolutionary computing is good for search and optimization. Medical diagnosis are challenging due to their complexity and the uncertainty involved in the inherent decision making process done by Medical Doctors. In our work the proposed approach is to build powerful hybrid intelligent systems for achieving the automated medical diagnosis. The proposed hybrid architecture is based on modular neural networks for learning form large datasets of patients. Then for combining the outputs of the modules an integration based on type-2 fuzzy rules is performed for modeling the involved decision making process, as well as the inherent uncertainty in making the decisions. Finally, evolutionary or bio-inspired optimization techniques are used for optimizing the architectures of the neural networks, as well as the structures of the type-2 fuzzy systems. The proposed hybrid architecture has been tested and applied in different medical diagnosis problems with good results. In particular, we can mention hypertension diagnosis, arrhythmia diagnosis and diabetes diagnosis and detection of pulmonary diseases. We believe that the proposed hybrid intelligent approach can also be used for other diagnosis problem in the future.
