Barr and Feigenbaum in 1981 defined AI as “Artificial Intelligence (AI) is the part of computer
                 science concerned with  designing intelligent computer systems, that is, systems that exhibit
                 characteristics  we  associate  with  intelligence  in  human  behaviour—understanding  language,
                 learning, reasoning, solving problems, and so on.”


                         Domains of AI

                 The  domains  in  AI  encompass  various  specialized  areas  where  intelligent  machines  and
                 algorithms are developed to tackle specific challenges and applications. These domains include.











                          Natural Language
                              Processing                       Data Science                   Computer Vision




                 Natural Language Processing (NLP)
                 This is a subfield of AI which helps in communication between human and computer in natural
                 language. It enables a computer to read and understand data by mimicking human natural
                 language.
                 This subfield of AI is used for a variety of tasks such as email filters. A lot of people receive a lot
                 emails which are useless. NLP checks the sender of the email and categorises the mails as spam
                 or junk. NLP also finds its use in the auto complete and spell check feature of word processors.
                 NLP also proves to be quite useful in voice text messaging and virtual assistants.
