1. Servo: Data was from a simulation of a servo system
2. Computer Hardware: Relative CPU Performance Data, described in terms of its cycle time, memory size, etc.
3. Synchronous Machine Data Set: Synchronous motors (SMs) are AC motors with constant speed.A SM dataset is obtained from a real experimental set. The task is to create the strong models to estimate the excitation current of SM.
4. Energy efficiency: This study looked into assessing the heating load and cooling load requirements of buildings (that is, energy efficiency) as a function of building parameters.
