Process Speed up

Hello together,

is there a possibility to speed up a process? I am currently conducting a dimensionality reduction process with SVD - the process took 5 days and is still running. Is that normal?

Thank you in advance for your help!

hi @Muhammed_Fatih_ so the answer to this is "it depends". How many rows and columns are in your data set? What are the capabilities of your computer? Sometimes RapidMiner needs hours to go through large data sets - it depends.

The matrix (word vector) has 9662 attribute columns (terms) and in total 72826 rows. My SVD process is running for four days and has not finished yet. Especially the SVD operator itself is still loading. I have a 32 GB memory on my computer and an i7 core.

@Muhammed_Fatih_ yeah so that's a LOT of columns. If it's a result of text mining (word vectors), why don't you use pruning to reduce dimensionality rather than SVD?

My research goal is to evaluate the effect of different dimensionaity reduction algorithms.

But beside that - very interesting hint: Which criteria would you use for pruning? Where is the cut to set?
