detecting faces in cluttered backgrounds and real world has remained as an unsolved problem yet. in this paper, by using composition of some kind of independent features and one of the most common appearance based approaches, and multilayered perceptron (mlp) neural networks, not only some questions have been answered, but also the designed system achieved better performance rather than the pre...

In machine learning, the structure of feature space is an important factor that determines performance a model. Therefore, we can deepen our understanding learning algorithms if visualize changes in during process. However, visualizing such difficult because it requires dimensionality reduction while maintaining consistency with data high-dimensional and temporal direction. this study, visualiz...
