You mentioned ML lets us do X; did you try federated learning? Our team saw privacy issues but improved accuracy.

Which part of ML amazed you most—model interpretability, speed, or deployment? In our last project, we struggled with interpretability.

I'm curious, what specifically about machine learning amazed you? Was it the rapid progress or its applications?

I've found that the biggest challenge is not the ML itself, but getting quality data to train the models.
