Frequently Asked Questions

Does scikit learn support categorical data??

However scikit-learn implementation does not support categorical variables for now. Other techniques are usually specialised in analysing datasets that have only one type of variable. See algorithms for more information. Able to handle multi-output problems.

Can I use one hot encoding for categorical data in scikit learn??

You can find more information in the scikit-learn documentation if needed. If a categorical variable does not carry any meaningful order information then this encoding might be misleading to downstream statistical models and you might consider using one-hot encoding instead (see below).

How does scikit learn classification work in Python??

Scikit learn Classification Report Support In this section, we will learn about how Scikit learn classification works in Python. A classification is a form of data analysis that extracts models describing important data classes. Classification is a bunch of different classes and sorting these classes into different categories.

What version of scikit learn do I need to deploy??

If you're deploying a scikit-learn model or an XGBoost model, this must be at least 1.4. If you plan to use the model version for batch prediction, then you must use runtime version 2.1 or earlier.
