Re: different results for Genie and Smile

Ok, but this -1 at the end could be an issue

If your cutoff is say 1.0 then the other should be 0

(1-1)/3 -1 = -1
or
0/(3-1) = 0/2 = 0

Same for 0.6

(1-0.6)/3 -1 = (0.4)/3 -1 = -0.87
or
(1-0.6)/(3-1) = 0.4/2 = 0.2

It does make a difference

So are you sure about this?

Re: Genie Sampling and fixed nodes

Ok, question why do want these specific nodes sampled?

Why would an exact algorithm not be an option for these nodes?

Are there specific requirements you need or other special circumstances?

Re: different results for Genie and Smile

Are you sure about what you put in f?

(1.0-cutoffvalue)/possibleColors-1

is the 1.0-cutoffvalue supposed to be divided by possibleColors or possibleColors-1?

Re: Genie Sampling and fixed nodes

Ok, let's summarize a few thing, please correct me if I'm wrong. - You have a network with discrete nodes (i.e. a discrete number of states for each node). - Some of the data for these nodes comes from sensors and the observed states are soft evidence. - You want to use an inference algorithm based ...

Re: Genie Sampling and fixed nodes

Just wondering something,

You always seem to be using soft evidence, why is that?

Re: different results for Genie and Smile

How do the results differ?
Are they big, or small, could they be rounding errors?

Re: Genie Sampling and fixed nodes

Well, yes if you have the joint probability distribution, you can do all the computations you would ever need, but the size of it grows exponentially and for anything beyond the usual toy problems they grow beyond what's capable of storing on one or multiple computers altogether. Wit just 32 binary ...

Re: different results for Genie and Smile

Hi Techmec,

How and where did you set the evidence?

btw. are you using the .xdsl format? the .dsl format is actually older and not really used anymore.

Best,

Re: Genie Sampling and fixed nodes

Hi techmec, No, it's not possible to sample the joint distribution. The sampling algorithms are use for inference. You can set a node to a value, by setting evidence, but this means setting it to a state, I'm not sure if that's what you mean. The mandatory option you found is used for something else...

Re: Bug: Spaces in path when compiling jSmile

Thanks for the feedback on that, I did notice that myself when I compiled it.

I'll see to it that it's fixed.

Btw, did you manage to compile a 64 bit dll? If so I'll won't have to email it (from your other post)

Re: Smile DLL x64 for jSmile

Hi Jonnie, This should help you compile Jsmile for 64 bit windows, but this is with the "full" VS 2010. I still have your email I believe, I'll send you the dll I've created with the following procedure. Download the jsmile source code Download the VS2010 64 bit SMILE and put it in the smi...

Re: Genie Sampling and fixed nodes

Hi techmec,

I'm not quite sure what you are trying to accomplish.
The term mandatory nodes doesn't really mean anything to me.

Could you describe step by step what you are doing at the moment?

Thanks,

Re: Compiler errors in Smile .NET wrapper

Hi Piotr,

I have been trying to reproduce the problem but haven't been able to.
Could you give me some more information about your setup?
OS, Visual Studio version, etc.

You can post it either here or send it to genie@sis.pitt.edu

Thanks,

Martijn
