其实模型中可以分为两种参数,一种是在训练过程中学习到的参数,即parameter也就是上面公式里的w,而另一种参数则是hyperparameter,这种参数是模型中学习不到的,是我们预先定义的,而模型的调参其实指的是调整hyperparameter,而且不同类型的模型的hyperparameter也不尽相同,比如SVM中的C,树模型中的深度、叶子数以及比较常...

Is it correct that the Regression Learner Toolbox uses the best parameters for each model? For example, in the case of trees, the accuracy depends on how many branches there are. Do regression learners use these parameters most accurately? Do svm, nnr, linear...
Detached off-grids, subject to the generated renewable energy (RE), need to balance and compensate the unstable power supply dependent on local source potential. Power quality (PQ) is a set of EU standards that state acceptable deviations in the paramete
The obtained results for different numbers of coefficients are presented in Fig. 4. In the case of the Cambridge COVID-19 Sound database, the accuracy of the SVM model initially improved as the number of coefficients increased. However, after reaching a peak at around 30 coefficients, the acc...
