Neural network algorithms, also known as artificial neural networks or simply “neural networks”, are a class of machine learning algorithms that are modeled after the structure and function of the human brain. They are used for a variety of tasks, including classification, regression, and pattern recognition.
Neural networks are composed of layers of interconnected nodes, or “neurons”, that process information. Each neuron receives input from other neurons or directly from the data, applies some computation to the input, and produces an output that is sent to other neurons or to the output layer of the network.
The connections between neurons are weighted, meaning that some inputs are more important than others in determining the output of a neuron. During training, the weights of the connections are adjusted to minimize the error between the predicted output of the network and the actual output.
There are several types of neural network architectures, including feedforward networks, convolutional networks, and recurrent networks. Each architecture is designed to handle different types of data and tasks.
Neural networks have been successfully applied to a wide range of applications, including image and speech recognition, natural language processing, autonomous vehicles, and even playing games such as chess and Go.
