Neural Network Structure Clarification Assignment Answers

Question:

Which of the following is/are true about the working and structure of Neural Networks? 1) In Feedforward Neural Networks, information flows from the output layer to the input layer. 2) During backpropagation, the weights are updated starting from the input layer to the output layer. 3) The first hidden layer should have exactly as many neurons as there are in the input layer.

Neural Network Structure Clarification Answer and Explanation

- This statement is true. During backpropagation, the error is calculated at the output layer and then propagated backward through the network to update the weights. The weights are adjusted based on the gradient of the error with respect to the weights, and this process starts from the output layer and moves towards the input layer.

3) The first hidden layer should have exactly as many neurons as there are in the input layer.

- Statement 3 is not necessarily true.
