Re: Bayesian Research -- Different networks with same initial parameter

Post two networks learned with identical seed here, so we can investigate the problem.

Dear shooltz,

I tried several times and I find the error! In step 3 I put sample size (confidence level) 50 instead of 100, it causes different results because Genie pick up randomly half of the samples (50 ...

Re: Bayesian Research -- Different networks with same initial parameter

Don't mix strenght of influence and sensitivity analysis. Use one or the other. I recommend sensitivity analysis for your case.

I tried Strength of influence firstly, the final influence diagram is different. Then I tried only Sensitivity Analysis , the result is not the same neither.

As the ...

Re: Bayesian Research -- Different networks with same initial parameter

find the influence value of each parameter related with KEA(my last parameter)

Apply sensitivity analysis for this. See Using GeNIe | Bayesian Networks | Sensitivity analysis in Bayesian networks chapter in GeNIe manual.


Thanks very much for your prompt reply.

I also tried Sensitivity ...

Re: Bayesian Research -- Different networks with same initial parameter

You're using random seed value of zero, which means that actual seed is taken from the system clock and a couple of other system values. To obtain repeatable results, use nonzero seed.

Thanks a lot!!! I put seed 1 and now I get the same network !

Hope you do not mind.... I have another question ...

Bayesian Research -- Different networks with same initial parameter

Dear all,

I am a new Genie user and I have a doubt with Genie.
I tried to find the relationship(network) of some items by using Genie. I followed next steps:

1. I got my file in format csv.
2. Discretization of each row. There are 8 parameters (colums) and 590 rows.
3. Learn new network. I choose ...
