                 Computer science has changed how we live, work, and use technology, leading to progress in areas like artificial
                 intelligence, data science, cybersecurity, and robotics. It helps solve difficult problems using smart programs, automation,
                 and data analysis. Before learning about modelling, let us first revise some of the basic terminologies of AI.

                         Revisiting AI, ML, DL


                 AI is a broad field that encompasses various technologies, including Machine Learning and Deep Learning.
                 These technologies are interconnected and can be understood as follows:



                                                                          It is the ability of machines to simulate

                                                                          human intelligence.

                                                                          It is a subset of Artificial Intelligence that
                                      Machine Learning                    enables  machines to  learn  from  data
                                                                          and improve their performance without
                                                                          explicit programming.

                                                                          It is a subset of Machine Learning that
                                      Deep Learning
                                                                          uses neural  networks  to process large
                                                                          amounts  of  data  and  solve  complex
                                                                          problems.

                 Let us understand AI, ML and DL in detail.
                 AI


                 Artificial Intelligence (AI) is a fast-growing technology that allows machines to do tasks that usually need human
                 intelligence, like learning, solving problems, and making decisions. It imitates some abilities of the human brain,
                 such as recognising patterns and understanding information, but it cannot fully match the brain’s complexity.
                 ML


                 ML stands for Machine Learning, which is a subset of Artificial Intelligence. It uses statistical methods to enable
                 machines to learn and improve from experience without being explicitly programmed. Machine Learning is one
                 of the most widely used techniques for building AI systems worldwide. It involves teaching machines to interpret,
                 process, and analyse data to solve problems effectively.
