alt Hacker NewsYes, you can do Cryptonets. What I’m saying is that you don’t have to do cryptonets, you can simply use FHE to train the network in fully encrypted manner: both the network and the data are FHE-encrypted, so the training itself is an FHE application. It would be insanely slow and I doubt it can be done today even for “small” LLMs due to high overheads of FHE.
> This is why FHE for ML schemes [1] don't try to make ML models work directly on encrypted data, but rather try to package ML models so they can run inside an FHE context.
I don't think @strangecasts was trying to say you couldn't. I believe their point was that you can't have a model learn to coherently respond to encrypted inputs with just traditional learning mechanisms (so without FHE). Doing so would require an implicit breaking of the encryption scheme by the model because it would need a semantic understanding of the plaintext to provide a cogent, correctly encrypted response.
