rocObj = rocmetrics(Y(testInds),posterior,Mdl.ClassNames); Plot the ROC curve for the second class by using the plot function of rocmetrics. Get plot(rocObj,ClassNames=Mdl.ClassNames(2)) The AUC is close to 1, which indicates that the model predicts labels well.Input...

Fit a linear regression model, and then save the model by usingsaveLearnerForCoder. Define an entry-point function that loads the model by usingloadLearnerForCoderand calls thepredictfunction of the fitted model. Then usecodegen(MATLAB Coder)to generate C/C++ code. Note that generating C/C++ ...
If you require determinism when performing deep learning operations using a GPU, use the deep.gpu.deterministicAlgorithms function (since R2024b). If you use the rng function to set the same random number generator and seed, then predictions made using the CPU are reproducible....

Predictor model, returned as a dynamic system model. For multi-experiment data,sys_predis an array of models, with one entry for each experiment. You can use the predictor modelsys_predand estimated initial conditionsicto reproduce the results of prediction: ...

In Example 2, I’ll illustrate how to apply the predict function without getting the “Error in eval(predvars, data, env) : numeric ‘envir’ arg not of length one”. Have a look at the following R code: pred_values2<-predict(my_mod, data_2)# Proper specification of data argumenthea...
