[P] Training Models on Encrypted Data

Hello,

We recently released a way to train machine learning models on encrypted data. This is all available with data science friendly APIs in [concrete-ml](https://github.com/zama-ai/concrete-ml).You can read the full blog post at

For the implementation details: we extract the onnx graph of a PyTorch training session (for now a logistic regression) and convert it into a numpy function. This then gets turned into a FHE circuit with the help of [concrete](https://github.com/zama-ai/concrete). This circuit has then the capability to be …
