Hello,
I interested in adding reference to the "Greedy Thick Thinning" algorithm in my work.
Is there an option to get some place where i can find an article that explains the "Greedy Thick Thinning" algorithm ?
Thanks,
Boris

Re: Continuous/Discrete
Suppose the column contains only integers : 1,2,3,4,5,...,50,.....1000 this column esteemed as Continuous or Discrete ? If you're asking about the type of the column as inferred by DSL_dataset::ReadFile, then the answer is 'discrete'. What is the "Discrete threshold" feature in GeNIe ? Is...

Hello,
How the SMILE's algorithm recognize if the column type continuous or discrete ?
Thanks,

I am asking about the computational complexity (time complexity).mark wrote:Just to clarify, are you asking for the actual running time or the computational complexity?

Re: Learning structure
Do you mean to ask if there is a difference? In general, the runtime depends strongly on the connectivity of the graph you are trying to learn (i.e., the number of conditional dependencies in the data). I actually intended to ask the run time for the greedy algorithm as function of nodes . Separate...

Re: Learning structure
Can you please indicate the run time for the greedy algorithm when using the K2 and BDeu ?mark wrote: K2 and BDeu are prior distributions over parameters used in the score metric.

Re: Learning structure
If the arc can be reversed it means there is a direct correlation between the variables, but the causal relationship cannot be determined Are these kind of arcs presented ? K2 and BDeu are prior distributions over parameters used in the score metric What the BDeu's weights meaning? Thanks, Boris

Re: Learning structure
In a nutshell, the arcs are causal, unless an arc can be reversed without changing the set of conditional independencies that hold for a given graph. The learning is unsupervised. If the arc can be reversed without any changing it will be deleted or appear as correlated? Another question: The K2 an...

Re:
Please refer to Heckerman's "A Tutorial on Learning With Bayesian Networks" for an explanation of GreedyThickThinning. Essential graph search starts from a graph obtained by applying PC and then continues with a GreedyThickThinning search (and it also does multiple restarts). The learning...

Parser with C#
Hello, I trieds to execute => Parse(filename) function but without success. How i can use the "TextParser" class ? comment: my code contain the "using Smile.Learning" row. When i using the : myDataSet.ReadFile(filename) Is the parser executed automaticaly? Thanks in advance, Boris

Re: Using DataSet
Is there an option to copy all the Items from C# Dataset to Smile Dataset ? Another question if i can read specific table from access Db (Like GeNIe allows). No, there's no .Net-specific functionality in Smile.Learning.DataSet. You'll need to iterate over the contents of your ADO.NET (or whatever d...

Learning Bayesian Network From Data
Hello,
When i open the file (that attached) and try to learn the network with Greedy algorithm i get network without connections at all.
The result appears immediately in other words , seems that GeNIe not try to run the learning at all.
What can be the problem?
Thanks,
Boris
