    DATA SCIENCE

                      Data science is the field that deals with collecting, analysing and interpreting large sets of data.
                      It helps machines learn patterns from data and make decisions or predictions. Data may include
                      numbers, text, images, videos or other types of information that can be stored and examined. It
                      combines key areas such as mathematics, statistics, computer science and domain knowledge to
                      recognise patterns within data. These patterns help both humans and machines make informed
                      decisions and address real-world problems effectively.

                      Data science function of AI is enabled by:
                        Data collection and preparation: Raw data is gathered from different sources and organised

                         carefully so that it becomes accurate and suitable for building useful models.
                        Model training: AI systems are provided with prepared data to recognise patterns and make
                         reliable predictions.

                        Continuous improvement: Data scientists repeatedly examine and refine models using new
                         data to enhance accuracy, a process called feedback loops.

                                                                           AGENT

                        Why should a separate test dataset be used to evaluate the model, instead of the training data?

                      Applications of Data Science

                      Data science can be used for the following applications:

                                                 Transportation  experience and  logistics: AI uses  GPS  tracking,
                                                   traffic updates and weather forecasts to determine the fastest and
                                                   most efficient delivery routes. Sensors in vehicles also provide real-
                                                   time information how well the vehicle is running, helping to identify

                                                   when maintenance is required and preventing breakdowns.
