I'm new with Text Mining and Rapidminer. I want to learn difference between these two operators. and also, is LSA (Latent Semantic Analysis) different technique or same as SVD.

Hi @LevenD, those to operators are totally different algorithms. You can use SVD in the LSA to do the same thing (topic detection) but algorithmically they don't have anything in common. Best, Martin

mschmitz "You can use SVD in the LSA to do the same" actually this is exactly what i'm looking for. Do i have a chance to do in Rapidminer with operators ?

Look at these links please I think you can find a lot of information for these operators
https://docs.rapidminer.com/latest/studio/operators/modeling/predictive/discriminant_analysis/linear_discriminant_analysis.html
https://docs.rapidminer.com/latest/studio/operators/cleansing/dimensionality_reduction/singular_value_decomposition.html
I hope this helps
