5.   AI tools can generate new ideas, explore possibilities, and    repetitive tasks.
                   6.   Artificial Intelligence, where Artificial defines "  " and Intelligence defines “thinking ability”.

                   7.   There are              players in Turing Test.
                   8.                 has intelligence more than human beings, it can do tasks beyond human capabilities.
                   9.   This type of data lacks any specific organisation, making it more challenging to analyse compared to structured
                       data. This data is called         .

                   10.  NLG is a subfield of NLP, but instead of understanding, it focuses on    human language.
              C.   State whether the following statement is true or false.
                   1.   Data science focuses on processing text and speech inputs so computers can understand,
                       interpret, and generate human language.
                   2.   Cognitive computing understands and simulates reasoning.

                   3.   Self-driving cars use computer vision to navigate roads safely.
                   4.   Cancer researchers use deep leaning to automatically detect cancer cells.

                   5.   Machine learning is divided into 2 main categories.


                                                SECTION B (Subjective Type Questions)
              A.   Short answer type questions.

                     1.  Define machine learning. Also, give two applications of machine learning in our daily lives.
                   Ans.   Machine learning is a subset of Artificial Intelligence that enables machines to improve at tasks with experience
                       (data). The goal of machine learning is to enable machines to learn by themselves using the provided data and
                       make accurate predictions and decisions.
                        Machine learning is used in Snapchat Filters, NETFLIX recommender system.

                     2.  Differentiate between Artificial Intelligence, Machine Learning, and Deep Learning.
                   Ans.

                     3.   Explain supervised learning. Also, name two algorithms that use supervised learning and two real-world applications
                        of supervised learning.
                   Ans:   In supervised learning, the machine needs external supervision to learn from data. The supervised learning models are
                       trained using labelled data. Regression and classification are the two main algorithms that use supervised machine
                       learning. In the real world, supervised learning can be used for risk assessment and fraud detection.
                     4.  The goal of reinforcement machine learning is to maximise rewards. Explain the statement.
                   Ans.  In reinforcement learning, the AI machine/model faces a game-like situation. The machine uses trial and error to
                       come up with a solution to the problem. The machine gets either rewards or penalties for the actions it performs. It’s
                       up to the model to figure out how to perform the task to maximise the reward, starting from totally random trials
                       and finishing with sophisticated tactics and human-like skills.
                     5.  Define computer vision.
                   Ans.  Computer vision is a branch of AI that involves extracting information from digital images such as videos and
                       photographs, analysing them and understanding their content.
