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%) to ...

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 influe...

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 Analysis , bu...

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: as...

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 Ba...
