    Question Identifying relevant predictors and interactions

    I have a data set comprising of 12,000 observations and 1,100 potential predictors (continuous and nominal) for a binary outcome/target variable.

    The research question is to identify interesting predictors and interactions for the binary outcome/target variable.

    Given the large number of potential predictors, I would like to exclude irrelevant predictors before modelling the data. Can somebody please recommend methods for feature selection that take interactions into account?
