Chapter 16 typos and duplicate code chunks

[gunnergalactico]

Online version of book.

chapter 16.1 reads:

"16.1 WHEN PROBLEMS CAN DIMENSIONALITY REDUCTION SOLVE?"

16.5.1 Principal Component Analysis repeats a code chunk.

"bean_rec_trained %>% step_pca(all_numeric_predictors(), num_comp = 4) %>% plot_validation_results() + ggtitle("Principal Component Analysis")"

16.5.2 Partial Least Squares repeats a code chunk.

"bean_rec_trained %>% step_pls(all_numeric_predictors(), outcome = "class", num_comp = 4) %>% plot_validation_results() + ggtitle("Partial Least Squares")"

16.5.3 Independent Component Analysis

"bean_rec_trained %>% step_ica(all_numeric_predictors(), num_comp = 4) %>% plot_validation_results() + ggtitle("Independent Component Analysis")"

16.5.4 UNIFORM MANIFOLD APPROXIMATION AND PROJECTION repeats code chunk

"library(embed) bean_rec_trained %>% step_umap(all_numeric_predictors(), num_comp = 4) %>% plot_validation_results() + ggtitle("UMAP")"

"bean_rec_trained %>% step_umap(all_numeric_predictors(), outcome = "class", num_comp = 4) %>% plot_validation_results() + ggtitle("UMAP (supervised)")"

Thank you for all your hard work.

Can you give us a little more info about the problems you are seeing? I believe this is as intended. Notice that the PCA section uses step_pca(), the PLS section uses step_pls(), and so forth.

Attached is a screenshot, not sure if it's my browser. I use safari and chrome. Thank you.
