smile exception -43 all potential entries are zeros

[thoriqsalafi]

Hi,

I am using jsmile for android and I think I have define all the nodes and the state as well as the connection, and seems it is working after I execute 2 or 3 times, but after 4/5 times I update to a new belief there is error like this

/AndroidRuntime(1954): Caused by: smile.SMILEException: SMILE error -43 in function UpdateBeliefs. Logged information: All potential entries are zeros for node ....
06-03 09:58:46.590: E/AndroidRuntime(1954): All potential entries are zeros for node ... etc

so what is the problem here? and how to solve it? thanks

so what is the problem here? and how to solve it? thanks

It's usually one of these two:
- conflicting evidence
- network structure which yields the jointree where precision loss happens (for example the naive bayes network with single parent and 1000+ children).

Can you post your network here?

I cant save the node and get error -2 so this is my code for the network. please help thanks

I cant save the node and get error -2 so this is my code for the network.

Try calling Network.writeString() and copy its output. I'll also need the evidence which is set when you get the error -43.

thanks for help

i am confused because if i set the evidence like this, there is no error

Code: Select all

net.setEvidence("Home","No");

net.setEvidence("Dynamic","Yes");

i am confused because if i set the evidence like this, there is no error
...
but if I use this and select the spinner based on the above evidence I got error -43 it has been 2 days and I still got the error

This suggests that error -43 is caused by conflicting evidence. SMILE contains some built-in checks which reject the conflicts in evidence, but there are some undetected borderline cases.

To properly investigate the problem, I'll need your network in .xdsl format AND the evidence causing the error -43. I'll be more than happy to help you, but I'm not going to write an Android app to reproduce the issue. If you are unable to succesfully call Network.writeFile, use Network.writeString and dump it to log.
