When we train a model for classification, we call it a 'classifier'. When we train a model for regression, what do we call it?

The only thing I could think of was "regression model" or just "model", because it doesn't sound like correct English to say "the regression predicted a value of 0.5", whereas it does sound correct to say "the classifier predicted class 1".

You can always just call it a model. Or, even better, refer to the independent variables in the model that are doing the actual prediction. The model is merely a means for you to understand which variables can predict your target variable.
