Frequently Asked Questions
How do neural networks work?
A neural network is a computational model that is inspired by the structure and functions of the human brain. It consists of interconnected artificial neurons that process and transmit information. The network learns by adjusting the strengths of connections between neurons, which allows it to recognize patterns, make predictions, and solve complex problems.
What are the main components of a neural network?
A neural network typically consists of three main components: input layer, hidden layer(s), and output layer. The input layer receives input data, the hidden layer(s) performs computations and transforms the input, and the output layer provides the final results based on this transformed information. Each layer contains multiple neurons connected to each other.
What is the role of activation functions in neural networks?
Activation functions introduce non-linearities to the output of each neuron in a neural network. They determine whether a neuron should be activated or not based on its inputs. Activation functions help neural networks model complex relationships and learn more effectively by allowing them to approximate any function regardless of linearity. Common activation functions include sigmoid, ReLU, and tanh.
What is backpropagation and why is it important?
Backpropagation is an algorithm used to train neural networks by updating the network’s weights and biases. It calculates the gradient of the loss function with respect to the network’s parameters and adjusts the values of these parameters accordingly. Backpropagation is essential for neural networks to learn and improve their performance over time.
What are the limitations of neural networks?
Neural networks are prone to overfitting, where they become too specialized on the training data and fail to generalize well to unseen examples.
