Brief overview of neural networks
A neural network is a mathematical model inspired by the structure and functioning of the human brain. It consists of interconnected artificial neurons, also known as nodes, organized in layers. Each neuron receives input signals, performs calculations using weights and biases, and produces an output that becomes the input for the next layer. Neural networks are trained using a process called backpropagation, where the network adjusts its weights and biases based on the error between predicted and actual outputs. This iterative learning process enables neural networks to learn from large amounts of data and make accurate predictions or classifications. However, traditional neural networks suffer from limitations, such as vanishing or exploding gradients and difficulties in capturing long-term dependencies. These challenges have inspired the development of more advanced architectures, such as the Transformer neural network, which utilizes attention mechanisms to improve both parallelization and long-range interactions in the network.
