Narayanan (2022) reproducible.cs.princeton.edu We show that data leakage is indeed a widespread problem and has led to severe reproducibility failures. Speci fi cally, through a survey of literature in research communities that adopted ML methods, we fi nd 17 fi elds where errors have been found, collectively affecting 329 papers and in some cases leading to wildly overoptimistic conclusions.
step_select_vip( artist, outcome = vars(popularity), top_p = tune() ) lm_res <- workflow(selection_rec, linear_reg()) %>% tune_grid(resamples = folds, grid = 25) The work fl ow makes sure that the appropriate computations are used with the right data at the right time
comes from a place of “This makes it too easy—you’re not thinking carefully about what the code is doing!” But I think this is getting it backwards. By removing the burden of writing procedural logic, I get to focus on scienti fi c and statistical questions about my data and model. varianceexplained.org/r/sliced-ml/
