it is good at voice recognition too and machine translation and recently applied to robotics.

My experience is that dl method is not as smart as a real human. you can't simply put data in and wait.

the trainer has to understand the data first. and then he needs to choose the best model for the data. sometimes it is black magic. sometimes you need to do many experiments, and in the end, you can't explain why this or that gives the best result. lots of manual work is involved.

but I should say I'm not that experienced with dl.
