Ah yes - that sounds like the stochastic gradient descent I've been hearing about. That makes a lot of sense for very expensive models. Thanks for the response

Ah yes - that sounds like the stochastic gradient descent I've been hearing about. That makes a lot of sense for very expensive models. Thanks for the response nshm - I've recently taken an interest in ML (coming in with some familiarity with optimization), and it's much appreciated to have some 'REPL' in the learning process.
