                                  c)  Unstructured data                      d)  Hybrid data

                        3.  Select the predictive technique used to estimate continuous numerical values.

                                  a)  Classification                         b)  Clustering

                                  c)  Dataset                                d)  Regression
                        4.  Mark the dataset which consists of data in the form of numbers.

                                  a)  Numerical dataset                      b)  Text dataset

                                  c)  Multimedia dataset                     d)  Image dataset

                        5.  Which term  is used  to  describe  a process  that  turns structured  data  into  meaningful  human
                            language?

                                  a)  Optical character recognition          b)  Speech recognition

                                  c)  Machine translation                    d)  Natural language generation

                     B.  Fill in the blanks using the given hints:
                        1.                  is used in AI where machines sort information into specific        Hints
                            categories.                                                                      Similarities
                                                                                                               Web
                        2.  In Clustering the data is grouped together based on              .
                                                                                                           Amazon Alexa
                        3.  Regression is used to make                about numbers.                        Classification

                        4.  A                 dataset is gathered from online sources like websites.         Predictions
                        5.  Google Assistant and                 understand spoken commands and respond to users in a
                            natural way.

                     C.  Write ‘T’ for true and ‘F’ for false.
                        1.  Speech recognition tranforms spoken language into machine-readable data.

                        2.   AI systems can learn from different types of data such as numbers, images and sounds.
