Thanks!

I read the post on the Indexing parents, but I fail to understand how it relates to my question. Indexing parents are parents , not the predecessors, so I don't see how to make the connection.

Another question on the same topic. Shachter's algorithm require expectations for values nodes ...

Hi,
Whenever I call this function, the returned set is empty, although the node has 5 parents.
According to the documentation, this function should return the list of node's indexing parents. IIUC, this means that the list should contain node's parents in the order they are used for setting the ...

Thanks!

What I don't understand from the example is how one finds the "best" values in the decision nodes, which yield the maximum utility, based on evidences. Example iterates through the list of indexing parents, which is enough if the network/ID is of height 1. What to do when the network is ...

Hi,
I have a rather simple question about SMILE. If I want to use it for solving Influence Diagrams, is this the usual workflow:
- set the graph/read it from the file
- manually update the probabilities based on the dataset
- calculate the expected values for utility nodes
- set some of the nodes as ...

Hi,
In my program, I read the network file, which has the default outcome names. I would like to update the outcomes dynamically (ie. while I read the data set from the separate file). So, I thought that by doing RemoveOutcome(i) or SetNumberOfOutcomes(0) I would annulate current outcomes.
Well, it ...

Hi,
I'm encountering something really strange. According to the documentation, IndexToCoordinates() should convert flat index to coordinates, for a given DSL_Dmatrix. When I try this:

std::cout << "MI4 " << kam.GetNumberOfDimensions() << std::endl;
std::cout << "MI4 " << kam.GetSize() << std ...

:) I'll do that right away...
I discovered that I don't need to call ReadFile at all, to get segfault. If I call theNet.Header().SetId("test"); it segfaults.

Solved! :)
I had a bug with pthreads. The object which contained theNet was created inside main(), which passed pointer to it to other ...

Can you write simple app which doesn't link to any other external library except SMILE and just calls ReadFile, then exits? If you get the segfault in that case, post the 'brutally simple file' here - maybe it's brutal, but not that simple :)

:) I'll do that right away...
I discovered that I don ...

Hi,
when I try to call theNet.ReadFile("/home/nikkne/test.xdsl"); it segfaults. File exists, it was created by WriteFile() call, and is brutally simple.

coredump's backtrace shows this:

Program terminated with signal 11, Segmentation fault.
#0 0x080f39c9 in DSL_header::SetId ()

Hi all,
I have a naive question :(

I have an influence diagram matching a real-world experiment. This diagram has only one utility node, and in the experiment I can observe the value corresponding to this utility node. Since the utility node maps utility value to the values in the parents node in ...

Weird, yet documented

Thanks!

Thanks! That worked...
I included Xlinker when I was desperate what can be the cause.

So, why this works?

Hi,

when I try to link against libsmile.a, I get the following errors:
/usr/lib/gcc/i486-linux-gnu/3.4.6/collect2 --eh-frame-hdr -m elf_i386 -dynamic-linker /lib/ld-linux.so.2 -o skuld /usr/lib/gcc/i486-linux-gnu/3.4.6/../../../../lib/crt1.o /usr/lib/gcc/i486-linux-gnu/3.4.6/../../../../lib/crti.o ...

Thanks Mark. I understand this.
I was referring to the case where I cannot go through the complete dataset (online incremental learning).

I have two questions...
1. how exactly Normalize() works?
2. Is there a better way of updating CPTs for a node, then this algorithm:

count <- number of observations for a Node
foreach dimension in CPT
p <- probability in the CPT
if this is the dimension we need to update
p <- (p*count+1)/(count ...
