Artificial Neural Networks(ANNs) also called Neural Networks are computing systems inspired by the biological neural networks that constitute human brains (and animal brains).
Neural nets resemble the connections between neurons and synapses found in the brain.
In neural nets neurons are segragated into layers. Information passes from firt layer (input layer) to the last layer (output layer) after traversing the layers. Different layer may apply different transformations on their inputs.
Application of Neural networks includes image recognition, image generation (GANs), translation, self-driving cars etc.
