[SOLVED] Similarity to data: sorting and selecting rows
I have used a data set to generate a matrix with the similarity values (using the Similarity to Data operator).
I would like to go through each example and:
1. sort the matrix row
2. select the top k elements
So far I managed to use a "Loop Example" operator to go over each data set line, however
I cannot seem to manage to extract the whole line (all attributes for sorting). How can I do this?
The "Extract Macro" operator seems to require that I indicate a single attribute .
Assuming I can get a data row I am also taking the opportunity to ask:
How do we sort and select the top k elements of a data row?
I have also looked t the "Sort" operator but that seems work on data set columns only.
