Web24 mei 2024 · In the previous version of mlr I could do something like; get the predictions using the test dataset and measure the performance of, say, the MSE or Rsquared values like so: pred <- predict (aqMod, newdata = aqTest) performance (pred, measures = list (mse, rsq)) Any suggestions as to how I can do this in mlr3? WebR is great for estimating statistical models using frequentist or Bayesian methods, and there are definitely tools for doing some ML in the language. Out of the box, it's better than Python regarding the root level libraries. Nonetheless, Python is what most of the ML community uses (either in torch or tensor flow). 0.
