Neural Networks: A Brief Introduction
Neural networks, at their core, are computing systems inspired by the biological neural networks that constitute animal brains. They are designed to 'learn' from input data by undergoing a process of training, allowing them to perform tasks without being explicitly programmed to do so.

The Structure of Neural Networks
A typical neural network consists of three types of layers: the input layer, one or more hidden layers, and the output layer. Each layer is made up of numerous interconnected nodes, or 'neurons', each of which carries out a simple computation on the data.

The Working Principles of Neural Networks
When data is fed into a neural network, it gets processed through the layers of neurons. Each neuron assigns a weight to its input, sums them up, applies an activation function, and passes the output to the next layer. During training, these weights are adjusted to minimize the difference between the network's prediction and the actual output, a process known as backpropagation.

Applications of Neural Networks
Neural networks are used in a wide variety of applications. They power image and speech recognition systems, enabling technologies like facial recognition and voice assistants. They also drive recommendation systems in e-commerce and streaming platforms, offering personalized suggestions based on user behavior.
