SOLVED: Performance Vector not showing / visible

Hi,

Fairly new to RM, I followed a couple tutorials. However neither the tutorials nor this forum could help me fix this issue. I followed this http://www.corequant.com/?p=1 tutorial step by step for Sentiment Analysis. Using RM 5.3.013 with (obviously) text processing extension. I never get the expected output, i.e. the Performance Vector. I am able to save the model and vector and apply it to unlabeled data; which yields results. However I want to know the performance of my model; what am I missing here? Why am I not getting any performance output?

My process:

Re: Performance Vector not showing / visible

Hi,

there is a slight piece missing on the screenshot of the tutorial: You need to connect the "ave" port of the 'Validation' operator to the process result ports, as you did with the "mod" port.

Regards,
Marco

You really are a hero-member. Thanks a lot.
