In Eureqa, I am getting solutions with a term "- *AE*Vsw", where "AE" and "Vsw" are variable names. What does "-*AE" mean? It doesn't seem to be the same as "- AE*Vsw" omitting "*", because the formula does not give reasonable agreement to the model in that case.
Hey @redenton, had a look into your question. Not sure if it is a visual bug but here for instance is a Eureqa formula like yours:
Here is the same formula displayed from the model logs:
There is now a number between the minus and asterisk.
Model Logs can be found here under 'log':
Not sure why its not displayed in the UI.
After rereading the formula it looks as though they are different. I'm not sure why the logs do not contain the formula displayed in the model
It is a visual bug, here is a model with the issue:
When I export the the model:
Great find! I agree that this looks like a visual bug - you may be able to see the correct expression by changing the rounding from 2 decimals to all (above the pareto chart). However, could you please send an email to support@datarobot.com to create a ticket? Provide all the information you shared here too. If you'd prefer, I can create the ticket - just let me know.
Thanks,
Jess
@IraWatt @JessLin Jess, I can create a support ticket for this. Ira's hint to look at the log was very helpful. I didn't know you could find the solutions there. Thank you Ira! Based on the log, the term in question should have been "-4.09020687809093e-7*AE*Vsw" instead of "-*AE*Vsw". Showing all digits did not fix the visual display when showing "Eureqa Solutions". Perhaps this means there is a problem in displaying a number if it is too small, like here with the e-7 notation.
@redenton Great to hear the logs were the answer. Just a note that the equation in my log was different from the Eureqa equation shown (don't know if this is also a bug), I found the correct term in the Eureqa export. I also suspect it could be because its a small number : D.
