Palisade: EvalMult between plaintext and ciphertext resulting in tower size mismatch
I hope someone can help me understand an error I get when using Palisades. I want to only use the first 329 slots of a BGV ciphertext, and zero out the rest (which at some point contains some 'rubbish' I don't want to re-enter the first 329 slots…

How are embeddings used for fully homomorphic encryption?
How exactly do you perform one way encryption using embeddings from a deep neural network?
Fully homomorphic encryption (FHE) benefits society by ensuring full privacy. The Private Identity recognition algorithm uses FHE to enable encrypted match…

The difference between Rotation and Galois Automorphism in RLWE-based FHE
The functionality of these two operations is similar, which confuses me.
What's the difference between them? And how they implement it respectively?
If I want to perform inner product (i.e., slot-wise accumulation), which operation should I use?

What is the multiplicative depth of a single relu layer for encrypted inference?
For a single square activation (x^2), the multiplicative depth is 1, and for a polynomial activation like x^3 + x, the multiplicative depth is 2.
For a convolution (wx + b), multiplicative depth is 1.
What's the depth for a single ReLU layer?
