# Frequently Asked Questions – Neural Net Excel

## Q: What is a neural network?

A: A neural network is a computational model inspired by the structure and functioning of the human brain. It consists of interconnected nodes or artificial neurons that process and transmit information through weighted connections.

## Q: How does a neural network learn?

A: Neural networks learn through a process called training. During training, the network is shown a set of inputs along with the corresponding desired outputs. It adjusts the weights of its connections to minimize the difference between its predicted outputs and the desired outputs.

## Q: What is backpropagation?

A: Backpropagation is a popular algorithm used to train neural networks. It calculates the gradient of the error function with respect to the network’s weights, enabling the network to update its weights in the direction that minimizes the error.

## Q: What is the activation function in a neural network?

A: Yes, neural networks can be used for regression problems. By adjusting the output layer and the loss function, a neural network can be trained to predict continuous values.

## Q: What is overfitting in neural networks?

A: Overfitting occurs when a neural network learns the training data too well, to the point that it memorizes the examples instead of learning the underlying patterns. This usually leads to poor generalization on unseen data.

## Q: How do you avoid overfitting in neural networks?

A: To avoid overfitting in neural networks, techniques such as regularization, early stopping, dropout, and cross-validation can be applied. These methods help prevent the model from becoming overly complex or too specialized to the training data.
