Question Regarding the Graz visualization Box
Posted: Thu Oct 12, 2017 8:16 am
Hey guys,
I'd like to use the Graz visualization Box to visualize the output of an LDA classifier. I am using a sigmoid function, so my output lies between -1 and 1. Now I would like the bar to be e.g. for 0.5 half extended to the right and for -0.5 half extended to the left. Testwise sending constant values it seems like any positive number will just extend it all the way to the right while negative numbers extend it all the way to the left. But when I use real data I also sometimes get a less extended bar. But I can't find a connection between the bar length and the numbers I give to the Box.
I have compared with Matrix Display in parallel, so I'm sure which numbers I send.
Can you tell me how the box computes the bar length? Does it somehow 'learn' from the maximum values used? Does it even work with just one output or do I need to give probabilities? (I also tried that, but with no success)
Cheers,
Simon
