2. Trial analysis of the relationship between loss function and performance measurement
Loss function and performance measurement The relationship between can be understood based on the optimization objectives. The optimization goal of the loss function is to minimize the difference between the predicted value and the actual value so that the model can better fit the data. The performance measurement focuses on the performance of the model in actual tasks. It may focus more on the accuracy, recall or other indicators of the model.
