perplexity term in genie
hello ^_^ i'm using DBN for language modelling; recently i've known that to test language model we have to test something called perlexity http://en.wikipedia.org/wiki/Perplexity : which measures the how predictive is the model for sequence of words?i've read about annealed map .is it the one? my wo...

low prediction accuracy in a variable state
hello !
when making validation (for unrolled DBN)for target node say A_2 at time= t2;A can have values {a1,a2,...,an}. for A=a3 validation gives accuracy 0(that is DBN fails in predicting this value). how can we know why?
how can we find explanation?

Re: DBN validation accuracy
Hello Marek!
this is sample from my data set .
I don't understand
I would be grateful if you tell me what do you think? the validation accuracy are not clear for me. if you would like i can send you the details. and other experiments

effect of one parent on child
hello ^_^
we have the CPT between nodes. how do we know to how much does a parent affect the child (this is the joint probability?)
how to document the learned network?

DBN validation accuracy
Hello ! I have 1. made DBN with 3 time slice and then train dataset=11261 case (the training used the default settings of genie) 2. I have performed the following experiments (the target node called POS) (temporal arc only on the node pos dbn.rar ) a. validate (2kfold)with class node pos at time t1 ...

validation,inference,learn
hello! 1. if we want to make parameter learning again. how to delete the probabilities for all nodes. 2. if we make inference in which the target node is predicted then this is validation? is that right? 3. cross validation is for managing the validation process. inference algorithm is used to predi...

hello ! geni crashes again with this message (This application has requested the Runtime to terminate it in an unusual way.). when i download dbn which I've made prameter learning using EM without making any target nodes and executes fine, but when i re-open it. it gives the crash message above. and...
