May I know if we can use loop nodes to stack operations on given data table?
for example,
operations table:
condition | operator | num_to_operate
band1 | "+" | 300
band1 | "*" | 2
band2 | "+" | 1000
input data table:
name | band | salary
lily | band1 | 5000
lucy | band2 | 4569
nancy | band1 | 3850
then, I'd like to operate according to operations table from top to bottom, in order to get final salary according to base salary. Here is the result I expect:
Output data table:
name | band | salary
lily | band1 | 12600
lucy | band2 | 5569
nancy | band1 | 8300
I know I can use "TableRow To Variable Loop Start" node to start a loop, then manipulate data according to variable. But when I get pass loop end and go back loop start node, how can I use datatable which has just been manipulated in input data table, instead of the very original table?
Currently, I just save the data to hard disk before loop end, and when next loop starts, I read the table again from hard disk......How can I do it in a more elegant way?
the term delegating stems from ensemble learning. The idea of delegating learning, is to in each run learn everything, and afterwards examples being not correctly classified are delegated to the next learner.
Here is a paper about it http://dl.acm.org/citation.cfm?id=1015395
When we developed the node we were not aware there would be so many other use cases of this functionality.
Em, data mining would be too narrow a positioning of this great tool. I did understand somewhat about data mining, which prevented me from using this great tool in the very past.
