The sample in the document does not seem to be clear about how tsai conducts the complete training process of Tabular Model. The sample only gives the most basic practice #688

I feel that the document is a little too simple. I can only run the following simple code now. How do I divide the training set, verification set, and test set, and what the dls contains, parameters, and training process? I feel a little confused when I first see this document
procs I see that the sample is filled with three value [Categorify, FillMissing, Normalize]，But these three do not seem to be variables because there is no definition in the sample. What does that mean.
And A similar problem is that I don't know where to add the splits defined in the code and what role they play

`procs = [] # 预处理操作列表，包括填充缺失值、标准化、类别编码等
y_names = ['result'] # 标签列名
df = pd.read_csv("./GfG.csv")

device = torch.device('cuda' if torch.cuda.is_available() else 'cpu')

splits = RandomSplitter(valid_pct=0.2)(range_of(df))
dls = TabularDataLoaders.from_csv('./GfG.csv', y_names=y_names,
cat_names = cat_names,
cont_names = cont_names,
procs = [Categorify, FillMissing, Normalize])

model = TabTransformer(dls.classes, dls.cont_names, dls.c)
learn = Learner(dls, model)
learn.fit_one_cycle(10, 1e-4)`

Hi @mtl121,
Could you please clarify which document you are referring to?

It doesn't point to which page, for example, the tabular model in the document's tabular model. If I use the GatedTabTransformer model of tsai to train the tabular data now, I can't start at all. The reason why I can't start is that I don't see a very complete training process from the document, and the document doesn't give a more detailed comment to the parameters of the model, Moreover, the sample given on Tabmodel's page is so simple that I can't use tsai to complete a table data task quickly

Hi @mtl121,
I'm planning to add a tutorial nb demonstrating how to use tabular models in tsai. In the meantime, I have created a gist to demonstrate how you can use tabular models in tsai. I hope you'll find it useful.

I don't know. I cannot commit to any date.
But if you have any questions in the meantime that are not covered in the gist I've just shared with you, create a new issue or open a discussion thread in "Discussions".
If the gist provided answers your initial question, you can close this issue.
