Hi Nantia, I replied to this but somehow I don't think my response got to the mailing list.
The GLM method http://madlib.apache.org/docs/latest/group__grp__glm.html does not support SVEC inputs for the parameter `independent_varname` . That parameter can be any expressions that resolves to an array, as in the example from the user docs: SELECT glm('warpbreaks_dummy', 'glm_model', 'breaks', 'ARRAY[1.0,"wool_B","tension_M", "tension_H"]', 'family=poisson, link=log'); Frank ________________________________ From: Nantia Makrynioti <nantiam...@gmail.com> Sent: Saturday, March 13, 2021 10:46 AM To: user@madlib.apache.org <user@madlib.apache.org> Subject: GLM with svec column in independent variables Hello, Is there a way to run the glm training function using a svec (sparse vector) column in the independent variables? I'm using the encode_categorical_variables function to transform a set of categorical features to a sparse vector for every tuple, but glm does not seem to accept this column as an independent variable. Thank you very much in advance, Nantia
