Neural Networks

5. (2 pts) If target vector information is not available for updating hidden layer weights in a multi-layer network, what other general learning approach could be used to update those weights instead? 6. (2 pts) Why is the generalized delta rule not a good model for how biological neurons update their synaptic connections? 7. (2 pts) When using error backpropagation, what are the names of the two mathematical variables /terms which are multiplied together to calculate the change/update for a connection weight? 8. (2 pts) When using the generalized delta rule, what is the name of the first step or forward pass of the training process? 9. (2 pts) When using the generalized delta rule, what is the name of the second step or backward pass of the training process? 10. (2 pts) What type of function is the generalized delta rule trying to minimize
