What Is The Backpculation Of Forward Propagation And Backpropagation?

Decent Essays

A. Forward Propagation and Backpropagation In case of forward propagation each node has the same classifier and none of them are fired randomly.Also repeating the input provides the same output.The question that arises at this point is if every node in the hidden layer receives same input, why dont all of them produce the same output?The reason is each set of input is modified by unique weights and biases [6]. Each edge has a specific weight and each node has a unique bias.Thus the combination of each activation is also unique and hence the nodes fire differently.Prediction of neural net depends on weight and bias.As prediction should be high it’s desired that the prediction value should be as close to the actual output as …show more content…

IV. PATTERN RECOGNITION USING NEURAL NETS For really complex problems neural networks outperform their competition.With the aid of GPU’s [1], the neural networks can be trained faster than ever before.Deep learning is specially used to train computers to recognize patterns.For simple patterns, logistic regression, or SVM are good enough. But when the data has 10s or more inputs Neural Networks are cut above the rest.For complex patterns, neural networks with a lesser number of layers become less effective.The reason is the number of nodes required in each layer grows exponentially with the number of possible patterns in data.Eventually, the training becomes very expensive and accuracy topples.Hence it can be concluded that for the
