i am using artificial neural networks for financial markets prediction. When i used " set macro" operator to optimize the number of hidden neurons, the program give me an error messsage. I did not understand this message error and i do not know how to solve the problem.
Thanks in advance
Solved! Go to Solution.
The problem is most likely caused by the fact that macros have the data type "string" and your process expects a numeric value. Please take a look at this post. It should help you to resolve the issue.
This is most likely caused by a wrong process order. You are requesting the macro value before it was generated. To change the process order of individual operators, click on the blue rectangle on the top right corner of the process pane (see picture below).
Have you tried running it like this? The warning you are seeing is caused by the process' meta data not being in sync with its real data. This is not uncommon when using macros and usually is only a warning, not an error. From your pictures, I believe you should be able to run it successfully like it is. In case it does not work, maybe you can post your process XML and I will take a look. For this you just need to copy the XML that you can find in your XML panel and copy it into this thread within the "Insert Code" tags (</>).
