What is Parameter Tampering?

Parameter identification technology is a technology that combines theoretical models with experimental data for prediction. Parameter identification determines the parameter values of a set of models according to the experimental data and the established model, so that the numerical results calculated by the model can best fit the test data (can be regarded as a curve fitting problem), so that Prediction of unknown processes provides some theoretical guidance.

Parameter identification technology is a technology that combines theoretical models with experimental data for prediction. Parameter identification determines the parameter values of a set of models according to the experimental data and the established model, so that the numerical results calculated by the model can best fit the test data (can be regarded as a curve fitting problem), so Prediction of unknown processes provides some theoretical guidance.

In specific research, a rough model is first established, and the model is used to predict the experimental measurement results. When the error between the calculated numerical result and the test value is large, it is considered that the mathematical model is inconsistent with the actual process or the gap is large, and then the model is modified and the parameters are reselected. When the prediction results are consistent with the measured results, the model is considered to have a high degree of reliability.
