i thought this was a problem of my model, but it doesn't work in the tutorial either. error message is "wrong connection. your connection is producing the wrong type of data. try changing the starting point of the connection."

hey guys,
we have applied the pca and chisquared methods to the topic of dimensionality reduction. this reduces the data volume considerably, which is my question: can i remove the main component analysis pca and leave the weight by pca method?
i would like to thank you for answering my question.

if you are not using then you can remove pca, if you just need weights from pca you can keep the current weights to pca  operator and remove the pca operator. you can tailor the process for your needs.
