All potential entries are zeros for node...

Post by cecciriccardo98 »

Hello
I am running inference on a Bayesian Network, specifically I am working with jsmile on a temporal diagram

specifically I am working on the unrolled diagram and when I do the updateBeliefs(), after setting nodes to an evidence (actually it happens even before setting any node), jsmile throws the following exception:

SMILE error -43 in function UpdateBeliefs [...]
All potential entries are zeros for node Target_Position_0
All potential entries are zeros for node Target_Position_1
All potential entries are zeros for node Target_Position_2
All potential entries are zeros for node Utility_0
All potential entries are zeros for node Utility_1
All potential entries are zeros for node Utility_2
Error when running Cooper's algorithm


where Target_Position_X is the Target_Position node at time X, which depends on the Target_Position_X-1 node.
Same goes for Utility_X

Can anyone help me understand what the problem is and how can I fix it?

This error can be caused either by lost of arithmetic precision (for very large network), or by an inconsistent probabilities/evidence. Can you post your model so we can diagnose this? If it contains sensitive information, send me a private forum message with a download link.
