I have been studying HE for few months, but now I have a question I can not respond to. I saw in literature that many papers use tons of bootstrapping procedures (especially in deep neural networks), but from my experience in OpenFHE, bootstrap destroys accuracy of my ciphertext (values are modified from the second decimal place on).
Is it something about parameters? Actually I am using the predefined ones (in the examples), but I am trying to understand them better
I have a question for what concerns Iterative bootstrapping though: since the precision is calculated on the plaintext, does it mean that the server itself can not calculate two iterations without asking the client to decrypt the ciphertext?
