Question

Difference Between Signals from Models and Signals from Dataset

Hello community,

(Post about thingworkx analytics)

 

I was curious about the difference from signals that come from a model (where you build a model and then create a signal from inside the model view) and signals that are made from the signals section.

From how I understood signals are calculated, there should be no difference (i.e. no influence from the model), although, after running some tests, we have noticed they are indeed different. The model choice does not appear to influence the signal values, but values that come from the two different section are different. 

Could someone please explain me this difference ?

Which of the two should I use ? 

Thank you for all your time,
Bernardo

Hi

 

When you create the signal form inside the model menu, the signal takes the same configuration as the model itself: same dataset, exclusion, filter ... this is not configurable

 

When creating the signal from the top menu, you can configure all the field to build a specific signal.

 

Hope this helps

Christophe

Hi Christophe, 

 

First of all, thank you for your time,

The thing is, we built a signal from the menu with a specific set of exclusion, a defined filter and a dataset.
Then we built a model with the exact same exclusion, the exact same filter and the exact same dataset and the two signals give different results.

To be more precise, the Mutual Information values for the fields were all diferent, and also was their order (so it is not just a scale difference).
Although, within each field, the values for average goal, difference to average and number of records where all the same. Only the MI values for each field were different.

So I'm assuming they are calculated differently,

 

Again, thank you for your time, 

 

Regards,
Bernardo
