How does Azure ML handle categorical columns during training a linear or logistic regression model?

How does Azure ML handle categorical columns during training a linear regression model? A linear regression model takes continuous values. However, even though I haven't changed anything of those categorical columns, Azure ML trains linear and logistic regression without error. So I would like to know how Azure ML manages to process categorical columns behind the scene. Thanks!

The linear regression module will only take numeric independent variables. Are you sure you had this working with categoricals in the linear regression?

It depends upon the model you are using, but you can get clues to how it's done by right-clicking on the "Train Model" element in your experiment, then clicking "Trained Model" -> "Visualize". The visualization will show you how it's used the supplied data.
