protectedvirtual |
Internal subprogram used by Create.
It explores newly defined cell with help of special short MC sampling. As a result, estimates of kTRUE and drive volume is defined/determined Average and dispersion of the weight distribution will is found along each edge and the best edge (minimum dispersion, best maximum weight) is memorized for future use. The optimal division point for eventual future cell division is determined/recorded. Recorded are also minimum and maximum weight etc. The volume estimate in all (inactive) parent cells is updated. Note that links to parents and initial volume = 1/2 parent has to be already defined prior to calling this routine.
If fNmin > 0 then the total number of (training) events found in the cell during the exploration is stored in the cell. This information is used withing PeekMax() to avoid splitting cells which contain less than fNmin events.
