[Question] Where can I find the initial set of candidate pipelines?

[amorimlb]

Hi, first of all, congratulations for such a useful and inspiring work!
I am working on a research project related to Auto-sklearn. Can you help me with the following information?
On the paper from Auto-sklearn 2.0, (https://arxiv.org/pdf/2007.04074) you describe in section 3.1 how you construct a portfolio given a finite set of candidate pipelines C. My question is where I can find this initial set of candidate pipelines. Are they organized somewhere in the directories here in the repository?

I have found some pipeline description in "configurations.csv" files, such as autosklearn/metalearning/files/accuracy_binary.classification_dense/configurations.csv, but I am not sure if these are the optimized portfolios or the initial set of candidate pipelines C, that you mention in the paper.

Thank you!

Hi @amorimlb,

Was just passsing-by, I am far from the team behind Auto-Sklearn but I have had to find that in the past so if that could help here is my answer (once again, not validated by current maintainers):

• Classifiers: https://github.com/automl/auto-sklearn/tree/development/autosklearn/pipeline/components/classification
• Data_Prep: https://github.com/automl/auto-sklearn/tree/development/autosklearn/pipeline/components/data_preprocessing
• Feature Prep: https://github.com/automl/auto-sklearn/tree/development/autosklearn/pipeline/components/feature_preprocessing
• Regressors: https://github.com/automl/auto-sklearn/tree/development/autosklearn/pipeline/components/regression

For each primitives of the portfolio, you can find their various HPs space in their specific files of the links above. For the rest, such as constraints between HPs, algorithms etc — Navigate backwards two folders from the above links.

Hope it helps!

Cheers
