This work aims to evaluate the use of traditional machine learning algorithms on features extracted from face images, in order to perform their recognition. The extracted features are based on the Principal Component Analysis (PCA), that represent each face as a n-dimensional vector, where n is less than the image size. The evaluated algorithms are distance classifiers, decision trees, support vector machines and neural networks, which were evaluated in their different parametrizations. The best accuracy results were obtained by the support vector machine and artificial neural networks models (99%), with the latter presenting the highest accuracy (97%) when the same model was tested in a new database.Trabalho de Conclusão de Curso (Graduação)Com o aumento da disponibilidade de dados de faces, o aprendizado de máquina se torna uma ferramenta bastant...
