            tidymodel error, when calling predict function is asking for target variable
            Asked 2021-Jun-10 at 19:13

            I have trained a churn tidymodel with customer data (more than 200 columns). Got a fairly good metrics using xgbboost but the issue is when tryng to predict on new data.

            Predict function asks for target variable (churn) and I am a bit confused as this variable is not supposed to be present on real scenario data as this is the variable I want to predict.

            sample code below, maybe I missed the point on procedure. Some questions arised:

            1. should I execute prep() at the end of recipe?

            2. should I execute recipe on my new data prior to predict?

            3. why removing lines from recipe regarding target variable makes predict work?

            4. why is asking for my target variable?

              ...

            ANSWER

            You are getting this error because of recipes::step_string2factor(churn)

            This step works fine when you are training the data. But when it is time to apply the same transformation to the training set, then step_string2factor() complains because it is asked to turn churn from a string to a factor but the dataset doesn't include the churn variable. You can deal with this in two ways.

            skip = FALSE in step_string2factor() (less favorable)

            By setting skip = FALSE in step_string2factor() you are telling the step o only be applied to when prepping/training the recipe. This is not favorable as this approach can produce errors in certain resampling scenarios using {tune} when the response is expected to be a factor instead of a string.

            Tidymodels - Help evaluating regression models made via recipes
            Asked 2021-May-24 at 23:31

            I am working with the current tidytuesday data about salaries and trying to create a model with tidymodels and recipes. I want to predict salary with many of the other factors present using the recipes code, but I run into an issue.

            Issue 1 - My recipe says there are empty rows, but I do not know how to figure out how. This does not give an error, so maybe it is not a problem.

            Issue 2 - Understanding what my models actually did and how to visualize the performance. I want to plot the models performance on the initial data. Here is an example of my goal: https://indescribled.files.wordpress.com/2021/05/image-17.png?w=782

            I do not understand exactly how to use the predict function with my recipe. juice(rec) is less than 1000 rows while the testing data is about 6000. Perhaps I am reading it backwards, but can someone try to point me in the right direction?

            The code below should be an exact reproduction of mine.

            If I understand correctly, you are trying to capture only one # symbol at the beginning of each line.

            The regular expression that helps you solve the issue is: r"(?:^|\s)(?:[#]\ )(.*\n+##\ ([^#]*\n)+)". The brackets isolate the capturing or non capturing groups. The first group (?:^|\s) is a non capturing group, because it starts with a question mark. Here you want that your matched string starts with the beginning of a line or a whitespace, then in the second group ([#]\ ), [#] will match exactly one # character. \ matches the space between the hash and the h1 tag text content. finally you want to match any possible character until the end of the line so you use the special characther ., which identifies any character, followed by + that will match any repetition of the previous matched character.

            This is probably the code snippet you are looking for, I tested it with the same sample test you used.

            I think a lot of what you did, specifically around data wrangling, was not necessary, especially since you called d3.hierarchy() and d3.cluster() afterwards. I've replaced this with d3.stratify (which deals with hierarchical data that is not yet in the right format).

            I've also replaced d3.cluster with d3.tree() because it was unclear to me why you'd want to use d3.cluster here. Your data has multiple parents, multiple roots and even floating nodes, and d3 is not meant to deal with that. My workaround has been to attach pseudonodes to every level, so as to make sure that there is only one node and that all nodes are at the right level at all times. To make sure the links were drawn correctly, I've written a custom getLinks function, that can deal with multiple parents.

            I've also written a custom link generator that draws the links somewhat in the way that you want them. d3 doesn't offer much of flexibility here, but you can use the source code for inspiration.

            Edit

            I've changed the logic to be more focused on which "partners" got a child, so both links to the same child are on the same level - like in your picture. I've also drawn the nodes based on how many partners they have, and have given every link an offset so the lines are more distinct.

            I've sorted the nodes so that the real pro-creators are at the top (Zeus), which gives a more balanced and less crowded view.

            Tidymodels Tuning Recipe Parameters
            Asked 2020-Jul-19 at 22:34

            Using tidymodels, I really love the possibility of tuning not only model parameters, but also some recipes steps. For example the number of components in step_pls(). The issue is that I'm finding trouble in limiting the range of possible values. For example, if I want to use step_umap I would like to limit the search space to 2:5 components. When I replace step_pls() by step_umap(), the following code causes the session to crash. It tries to build umap with around 50 components... So basically, my question is, while using grid_random or grid_max_entropy, how can I limit the range of search for a specific tuning parameter?

            Note: also tried something like param_grid%>%grid_random(size=5,num_comp() %>% range_set(c(3, 5))). But seems to be ignored.

            Thanks
