A general learning problem
 
Hello,
I am trying to find a good prediction model for a certain outcome on the basis of several variables. After taking a look at the data (plotting etc'...), I don't see any clear pattern. Does that mean that I cannot find a good predictor to my outcome? Is there a clever way to tell whether my outcome is predictable by my inputs or do I have to run different algorithms and see which one gives a good results?
Thank you,
Liron

Usually it is not a good practice to "see." Anyway, generally you can start "analyzing" parts of your data to see if there are basic input-output correlations, and/or try some simple models to assess the predictability of your data. Hope this helps.

Thanks for providing such a wonderful solution. We all are facing multiple problems with general learning and to cover up these issues, we need to run different algorithms to see which one gives a good result. Thanks for highlighting such issues, as an engineer, I would like to take some valuable data from here.

Good to know this. I was looking for the same solution.

I'm expecting the clever way,too. Wait for it online.
