skip the dimension reduction

hi marteen, i just wanna know what happen if we dont use the dimension reduction for the clustering?, and how to skip the dimension reduction step?he dimension reduc

If we do not use dimensionality reduction then the clustering will be directly done on the raw embeddings. You can find more about that here](https://maartengr.github.io/BERTopic/getting_started/dim_reduction/dim_reduction.html#skip-dimensionality-reduction).

in your experience what the difference between using the dimension reduction an not using it??

thanks

The link that I posted gives you an idea about the need to perform dimensionality reduction. You can also find more about that step in the pipeline here. In general, it is often advised to perform dimensionality reduction as clustering algorithms might have difficulties handling data in high-dimensional space.
