Since this is a thing I struggle a bit with myself, I thought it worthwhile to write up my thoughts. Note that I fully understand that not everyone has the luxury to think about their career like this – you...

This is a machine-aided translation of this Dutch post. Und jetzt auch auf Deutsch verfügbar! Everyone is tumbling over themselves making predictions about AI. It’s going to free us from menial work, it’s going to dismantle our education, we all won’t have to learn things anymore because the AI will do it for us,...

After having completed this series of blogposts (well done!) you should have a good grounding in what deep learning is actually doing. However, this was of course only a small 20k word...

This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! The previous chapters have often mentioned the chasm between “deep learning models that work on my data” and “it actually works in the real world”. It is perhaps for this reason that almost all...
