Machine Learning (ML) is an application of Artificial Intelligence based on the concept that machines should be given access to data and learn specific tasks by themselves, without being explicitly programmed. Artificial Neural Networks (ANNs) are a special type of ML algorithms inspired by the human brain and its functioning is similar to the way neurons work in our system. That is, just like how the neurons can learn from the past data, similarly, the ANN, in order to mimic the behavior of the biological neural networks, learn from the data and provide responses in the form of predictions or classifications.
