In a neural network, what does a fully connected architecture imply?

• Neurons are connected only to the output layer

• Neurons are connected randomly

• Each neuron is connected to every neuron in the next layer

• Each neuron is connected to every neuron in the same layer

What is the main purpose of backpropagation in neural networks?

• To propagate input data forward

• To initialize weights randomly

• To update weights by propagating error information backward

• To compute the output of the network

How does backpropagation help in training neural networks?
