Back Propagation Neural Network: Explained With Simple Example
The purpose has technically changed, but backpropagation works on error, not purpose, so it can be used without alteration in the new environment without issue. Purpose comes into play in the construction of the chromosomes to be used in the genetic process. Whereas previously researchers have used everything from individual weights to learning ...

ANNs attempt to replicate how the human learning process works and when given a sufficiently large set of training data, ANNs can model complex, i.e. nonlinear, relationships between the predictors and the predictand (Lippmann 1987). ... The ANN used here is a feed-forward neural network trained by a backpropagation algorithm (Reed 1998), which ...

The details for deriving the backpropagation algorithm can be found in the literature. 1.7 More neural network paradigms. So far, we briefly described how feedforward neural nets can solve problems by recasting the problem as a formal map. The workings of the backpropagation algorithm to train a neural network were formally explained.

Backpropagation doesn’t work directly with the very large elementary function; it uses a method that passes back through the network, calculating gradients as it goes along, but the concept is the same. ... One method works by training one support vector machine for each class. This SVM has the chosen class as one class, and every data point ...

a) What is the purpose of using N-fold Cross Validation? Explain in a few sentences how 2-fold cross validation works! [4] To determine the generalization error/training accuracy of the learn model (if they just say just accuracy give them on 0.5 points) [1.5] Correct description of 2 fold cross validation [2.5]

The most famous learning algorithm, which works in the manner described, is currently backpropagation. In the backpropagation learning algorithm online training is usually significantly faster than batch training, especially in the case of large training sets with many similar training examples [8]. 4.4 Generalization of Neural Networks
