Independent of DL, I'm curious why these two regression cases haven't been made available in a SQL-like interface until now. Kudos to Google for putting this in the hand of folks who otherwise just use SQL.

Oracle has had linear regression for well over a decade now.

Linear regression makes a lot of sense since it can be done streaming in a single pass. We have it as an aggregator in Hail: https://hail.is/docs/devel/aggregators.html#hail.expr.aggreg...
I wonder how they're doing logistic regression. It doesn't have a closed form and normally solved with an iterative, multi-pass optimization. edit: Read more closely. They're using (non-stochastic) batch gradient descent.

Good point! I wouldn’t be surprised to see a Postgres plugin for this. Wouldn’t get the vast scalability but it would offer convenience.
