Artificial Intelligence (AI) is a form of computer systems that can perform tasks that usually require human intelligence. It does this by analysing large amounts of data, identifying patterns and making decisions. AI is used in Machine Learning (ML) where the AI program starts to learn without the need for instructions. Natural Language Processing (NLP) is another application of AI which helps AI programs to understand, interpret, and process human language. AI has also made tremendous progress in the healthcare sector where doctors and medical professionals can use AI to analyse medical data and make diagnoses.
