Artificial Intelligence is the field of computer science concerned with building intelligent machines or computer systems, capable of simulating human intelligence. The machines created using Artificial Intelligence can work and react like humans without human intervention. Speech Recognition, Customer service, Recommendation Engine, Natural Language Processing (NLP) are some of the applications of Artificial Intelligence.

Since its inception, AI research has explored and rejected a variety of methodologies, including mimicking the brain, modelling human problem-solving, formal logic, massive knowledge libraries, and imitating animal behavior. Highly mathematical-statistical machine learning dominated the subject in the first decades of the twenty-first century. The many sub-fields of AI research are based on specific aims and the application of certain techniques. Reasoning, knowledge representation, planning, learning, natural language processing, sensing, and the ability to move and manipulate objects are all conventional AI research aims. One of the field's long-term goals is general intelligence (the capacity to solve any problem).  AI researchers have adapted and integrated a wide range of problem-solving strategies to handle these issues, including search and mathematical optimization, formal logic, artificial neural networks, and statistics, probability, and economics methodologies. AI also makes use of various fields like psychology, linguistics, philosophy.
