The analysis and classification of such encoded multimedia from unorganized and unstructured data is an important problem for information management and retrieval. In this paper we proposed an ANN based approach to classify text, speech and fax data. The normalized frequency of binary features of ...

The classification results showed that multilayer perceptron neural network employing back propagation-training algorithm was effective to distinct between the two classes, based on the good selection of the training data set samples. The correct classification rate was 100% for the training data sets ...
During the series of articles, we implemented an algorithm to perform binary classification, and we used a gradient descent optimization algorithm to learn the weight coefficients of the model. In every pass, we updated the weight vectorwwusing the following update rule: ...
