                     Case: Substantial Electricity Bill (Continued…)
                     You begin designing a sensor and alarm system that detects movement in the room. If there
                     is no movement, the alarm will sound to remind someone to turn off the lights and fans.




                          Evaluation—The Testing Stage


                  Evaluation is one of the most critical stages of an AI project. This phase is an important step
                  where we check how well the AI model works to see if it meets the goals set at the start. If the
                  model does not perform as expected, changes may be needed. Once the developer is happy that

                  the model works well and fits the project’s needs, the AI project moves to the next phase called
                  deployment.

                                                                                                   Skills

                    Case: Substantial Electricity Bill (Continued…)
                    After installing the sensor and alarm system in some classrooms, gather the following data:
                       • Reduction in electricity usage compared to the period before the system was installed

                       • Number of times the alarm went off and what actions were taken
                       • Feedback from teachers and students on how effective and easy to use the system is
                       • A comparison of the costs of installing and maintaining the system versus the money saved
                       on electricity

                       • Any technical problems or false alarms during the trial period

                    Use this data to decide if the system effectively reduces electricity usage and if it can be
                    used in all classrooms. Use this evaluation to improve the system before fully implementing
                    it.





                          Deployment

                  In this phase, the best model is put into real use. It is added to the actual system where people
                  can use it in everyday work. A system is also set up to watch the model’s performance regularly,

                  making sure it keeps giving correct and reliable results. If problems come up, like changes in data
                  or lower performance, the model is fixed and updated. The goal is to keep the model working
                  well over time and make improvements as needed.
