Hi, I am running Eureqa and there is something I don't understand about the solutions that I get. I have a number of input variables like "L", "Kp3", and "F10p73". The listed solutions are all in terms of these variables, except the last one often, though not always, appears as "F10p73-mi". Is that different from my variable name, "F10p73", in which case what does the "-mi" mean? The "-" there is not a minus sign. The whole of ""F10p73-mi" is bold white text, indicating normally a variable name. Thank you, Richard
Looking at my Eureqa models the dash indicates its referencing a specific class within your feature. For instance in my model predicting shot number I have a feature called player_name and its referencing lamarcus aldridge creating a variable "player_name-lamarcus aldridge".
@IraWatt Thank you so much for responding to my question. In my case, the data structure is very simple. It's only numeric data. There are no non-numeric values in that variable. And to my knowledge there is no class structure in the data. If there is some kind of class structure, I don't think it's something that I created. I tried renaming the variable names and running it again, but I have the same issue with that particular variable, now instead of "FT" I have "FT-mi". The first line of the data file has the column names "w, cyear, syear, L, cmlt, smlt, F, FT, AE, Kp, KpA, Dst, Bysw, Bzsw, Vsw, Npsw,Pdsw, lgrhoeq" and in the columns there is only numeric data. This screenshot shows data at the top of the file. Below that is a screenshot of the Eureqa model information.
Has DR identified FT as a Numeric type in the data tab? does 'mi' show in the data histogram? At a guess it could be 'missing values'. I sadly haven't found much documentation on the variable names, I'm sure a Eureqa expert in the community will know.
