Neural networks , also known as artificial neural networks (ANNs) or artificially generated neural networks (SNNs) are a subset of machine learning that provide the foundation of... What is a neural network ? A neural network is a machine learning model that stacks simple "neurons" in layers and learns pattern-recognizing weights and biases from data to map inputs to outputs. Neural networks are among the most influential algorithms in modern machine learning and artificial intelligence (AI). Researchers use Artificial Neural Networks (ANN) algorithms based on brain function to model complicated patterns and forecast issues. The Artificial Neural Network (ANN) is a deep learning method that arose from the concept of the human brain Biological Neural Networks . They are among the most powerful machine learning algorithms used today.
