                                             SECTION B (Subjective Type Questions)

            A.  Short answer type questions:
               1.  What is data exploration in AI project cycle?
              Ans.  Data exploration refers to the techniques and tools used to visualize data through complex statistical methods.
               2.  What do we do in the Evaluation stage of the AI project cycle?
              Ans.  Evaluation stage is the testing of the system, where we check if the model is capable of achieving required goals or not.
               3.  What is the role of iterative process in problem scoping?
              Ans.  The iterative process is an important approach of problem scoping that helps in continually improving a design or
                  product using an AI model.
               4.  What is the use of ‘Where’ block in 4W’s Problem Canvas?
              Ans.  In this stage, we check for where does the problem arise, the context of the problem.
               5.  What do you mean by Data Acquisition?
              Ans.  Data acquisition means collecting raw facts, figures or statistics from relevant sources either for reference or for analysis
                  needed for AI projects.
               6.  What is the use of data in an AI project?
              Ans.  Data plays an important part of an AI project as it creates the base on which the AI project is built.
               7.  What is a system map?
              Ans.  A system map is a diagrammatic representation of a set of things working together.

               8.  State the ways in which you can collect data.
              Ans.  Surveys, Web scraping, sensors, cameras, Observations, API.
                                                                                      AI Project Cycle  233
