Hi all, yes it's me again hehehe :)

I'm trying to read a data file and automatically discretize the parameters that are continuous, I've been reading the tutorial about discretization but it gaves the following code:

DSL_discretizer disc(d.GetVariableData(0));
disc.Discretize(3,DSL_discretizer ...

shooltz thank u very much, it works just great

Hi all!

I'm wondering if could be possible to use the same options that Genie provided us for ordering the nodes (Under layout menu option), to arrange the nodes to use them into our code with Smile.
The reason is that I generate some .xdsl files with networks and after open them in Genie I need to ...

Ah ok thank u very much shooltz I was confusing about that

Ok, I answer myself :) I've made the following function:


int findVarState(int varID,std:string stateName)
{
DSL_datasetVarInfo varInfo=m_dataSet->GetVariableInfo(varID);
for(int j=0; j<varInfo.stateNames.size(); j++)
{
std::string currentStateName=m_dataSet->GetStateNames(varID)[j];
if ...

Hi,

If I've the following file:
NO
YES
YES
NO

And I make read file, the state 0 will be NO and YES will be state 1,
but if you make in different order this will change.
I would like to know how it could be possible to get correctly the index of one read state to be able to use SetEvidence with the ...

Hi Mark!

I've checked that this node it's exactly the one i need using next sentence too for security:

const char* name=result.GetNode(i)->GetId();


And it gaves me the same order that it's reading (for the variable name). But as you point I think my problem is coming not from the variable ...

Hi Mark!

Here it's the code:


if (m_dataset.ReadFile(filename)!=DSL_OKAY)
ExitProcess(0);

if (greedy.Learn(*crossValid->m_dataSet,result)!=DSL_OKAY)
{
ExitProcess(0);
}

//result.SetTarget(m_studyData->getNumAttributes()-1);
int TARGET_INDEX=result.FindNode("Paliza");
result.SetTarget ...

Another example X)
The first line of the file is:

No No Yes No Yes

Where the last column is the class

So I go to Genie, and put the evidences of the first 4 nodes, and click Update Beliefs and I get in the class node:

Yes: 85%
No: 15%


But I read the file in my program and call SetEvidence ...

Hi Mark!

I'll try to explain myself better. (Btw I made mistake it shouldn't be difference<=1 but difference<=0.5)

The Class Node will have 2 values, Yes or No, but they're probability, because they're 2 different states not just one value that can be 0 or 1.
So if I read from the file that the ...

Hi all,

I'm making a simple test for check the percentage of the bn created.
For testing I just learn with whole data file:

crossValid->readFile("data.txt");
if (greedy.Learn(*crossValid->m_dataSet,result)!=DSL_OKAY)
{
ExitProcess(0);
}

int TARGET_INDEX=result.FindNode("Class");
result ...

Thank u very much schooltz, I added it and copyFrom(...) to have a copy function not just in the contructor.

The loop I think I've managed too ^_^

I'll post my version of K-fold when i'll get it working i think will be useful for someone.

Hi all,

I was looking thorugh the forum and i found it http://genie.sis.pitt.edu/forum/viewtopic.php?t=181&highlight=cross

I assume any changes since that post so I started to create my own crossvalidation function. The problem is that I was thinking to do something like the following:

DSL ...

I think I could answer myself
Instead of using GetEvidence (It's normal as you didn't declare it O:) )

Hi

I just looking throw the forum found this topic. I was trying to do something similar, but I don't know what I could be doing wrong.

First I learn my bn using a file dataset and greedy.

greedy.Learn(m_dataset,result)


Once I get the result bn I read the initial file and go through each ...
