I had a question regarding the max_card value set in the cont_cat_split method in the tabular lesson

Lesson 7 - Official topic

In the tabular chapter the cont_cat_split method is called with different max_cardinality parameters for the DT/RF model and the NN model as follows: #DT/RF cont,cat = cont_cat_split(df, 1, dep_var=dep_var) #NN cont_nn,cat_nn = cont_cat_split(df_nn_final, max_card=9000, dep_var=dep_var) The chapter does say that categorical columns are treated differently as it needs to create embeddings and indicates that embedding of size greater than 10k should not used and hence the 9k is used as max card…

Any thoughts?
