graph clustering algorithm (urgent help)
-
dear all
i'm working on a project that i have to deliver within 2 weeks from now and i have a problem which is
i'm building a recommender system that tracks user behavior then builds a graph of web pages
and after that uses incremental connected components to cluster web pages graph
my problem is that the step of building the graph and using incremental connected components are written in c++ using c++ boost graph library
and i work with vb.net and asp.net
and i have difficulty understanding this algorithm
so if any one can help me transform it into vb.net format or help me in writing the algorithm allover in vb.net
or give me another algorithm that i can use , as i already determined my graph using database instead of using data structure, link for algorithm is
http://www.boost.org/libs/graph/doc/incremental_components.html
http://www.boost.org/boost/graph/incremental_components.hpp
thanks for your patience
hope any one help me i'm in real need for that
accept all my regards

Bug in Merge node optimization (specify sort order)?
-
Whenever I try to use specified sort order function in a Merge node (Optimization tab), I get an error message like this one:
"Specified previous sort order invalidated at record: (8)"
Both tables are definitely in the specified order because I had just sorted them. Is this a bug?

Which date format can be detected automatically?
-
Is there a date format which Clementine can detect automatically in the Var. File Input node, so that it is not necessary to define the data type manually? I have been using YYYY-MM-DD but it is always detected as string.

Range Values in Clementine
-
Dear All,
I have this problem and i don't know what to do...for a specific field called "volume", any value exceeding 999,999 is turned to $null$.
I have tried to override the field type (which was setting to String rather than range) on the file Node and also i have tried to specify a range value on the type node....nothing works.
Is there anything else i could do?
Many Thanks
Harry

Predicting the real probability to be of certain category.
-
Is there a way, besides using the same amount of data for training as for the prediction, to get with neural networks or whatever a real probability value? Confidence is not probability, it's just useful to determine the relative probability with other records. Right now I'm just comparing to reality and creating sub groups with probability value.
Thanks!
