Abstract :
The applicability of AI methods to the Chagas´ disease diagnosis is carried out by the use of Kohonen´s self-organizing feature maps. Electrodiagnosis indicators calculated from ECG records are used as features in input vectors to train the network. Cross-validation results are used to modify the maps, providing an outstanding improvement to the interpretation of the resulting output. As a result, the map might be used to reduce the need for invasive explorations in chronic Chagas´ disease.
