Hi, i can´t understand what does it mean p_busq_idig:day_of_week = 1 or the other similiar attributes. As far as my concern, it´s seems that the automodel used the generate attribute operator and create new attributes, but how does automodel created this attributes? Do you know wich formula had been used?

    Hello @cdaponte

    Brian already mentioned what might be happening inside auto model regarding your attributes. If you would like to investigate in-depth, you can access the complete process behind the auto model. You just need to go click on "Open Process" and 



    I also see there is an option here in an auto model that is automatically checked called "Extract Date Information". This is performing different date-related calculations. I also highlighted that in the below image. If you uncheck this then there wont be any date related values taken by auto model.



    Once you open the process as mentioned above. There is a "preprocessing" block as shown below. Inside that preprocessing block, there is aa sub-process called "Handle date". This is where new attributes are being generated. Inside that, you can see all the processes happening on the date column.




    Hope this helps.

    I assume you have attributes called p_busq_idig and u_busq_idig as available attributes for prediction, and they are date/time formats. And then you checked the option in automodel to have it automatically generate new attributes and to include date/time attribute conversions. 
    When you select this option, it will look at various transformations of the Date to Numerical type to capture things like day of the week, month of the year, etc.
    In this case, it looks like the day of the week versions of these date/time attributes are very significant.
