The tidymodels framework is a collection of R packages for modeling and machine learning using tidyverse principles.

The tidymodels framework is a "meta-package" for modeling and statistical analysis that shares the underlying design philosophy, grammar, and data structures of the . It includes a core set of packages that are loaded on startup, and extra packages that are installed along with tidymodels but not attached on startup. The tidymodels framework provides tooling for modeling tasks including supervised machine learning (predictive modeling), unsupervised machine learning, time series analysis, text analysis, and more.

Prevent tidymodels from turning numeric to chr

Apologies if this has been asked before, but I was unable to find the corresponding info. I am using the recipe from tidymodels and trying to create a model (eventually). As I prepped my this is effectively what it looked like (apologies, I can't…

logistic_reg() estimates in tidymodels interpretation seem to be predicting incorrect class as positive outcome

I am using tidymodels to develop a logistic regression using the Palmer's Penguins dataset. I believe that female should be the reference class since it is the first level of my outcome variable, and therefore a positive outcome for the model should…

How can I pass an extra variable to a tidymodels fit function?

I am writing a tidymodels engine to fit the joint LASSO described here and implemented in the fuser package. This is a LASSO model for regression that allows partial sharing of information between groups, in this case tissues in a biomedical RNAseq…

tidymodels: f_meas metric_tweak error on metric_set

Using the iris dataset, a knn-classifier was tuned with iterative search for the purpose of multiple classification. However, an error is generated, when the macro-weighted version of f_meas (as created by metric_tweak) is used in metric_set. I…

Is there a metric for run times, or some other recommended way to collect runtimes when tuning a model in tidymodels?

I am using the tidymodels R package to fit a random forest model with the ranger engine, but I think this question is general to tuning any type of model tidymodels supports. When running my tuning grid, I would like to record the time it takes to…
