Understanding Neural Networks
What is a Neural Network?
A neural network is a form of artificial intelligence that is inspired by the structure and function of the human brain. It consists of interconnected nodes called neurons, which are organized in layers and capable of processing and transmitting information. Each neuron takes input from the previous layer, applies its activation function, and produces an output. The output of each neuron becomes the input for the neurons in the next layer, thus allowing the network to learn and make predictions.
How do Neural Networks work?
Neural networks work by utilizing a process called training. During training, the network is exposed to a large amount of data and learns to recognize patterns and relationships within that data. This is achieved by adjusting the strength of connections (weights) between neurons based on the error (difference between predicted and actual output) generated during the training process. The more data the network is trained on, the better it becomes at generalizing and making accurate predictions on unseen data.
Types of Neural Networks
Various types of neural networks can be used for different tasks. Some common types include feedforward neural networks, recurrent neural networks, and convolutional neural networks. Feedforward neural networks are the simplest type, where information flows only in one direction, from input to output. Recurrent neural networks, on the other hand, can maintain an internal memory and perform computations based on sequential data. Convolutional neural networks are specifically designed for image and video processing tasks and utilize convolutional layers to extract meaningful features.
