How to use the power of the community to learn faster

How to use the power of the community to learn faster

Community is the most powerful force behind online learning. It is the reason why MOOCs have a limited impact and tight-knit communities like fast.ai consistently produce unbelievable results.

How to train and validate on Imagenet

How to train and validate on Imagenet

Training on Imagenet is something that is completely trivial after you do it once, but if you are just someone on the Internet without such prior experience, it is an insurmountable task. Up until a couple of days ago, I didn't even know how to get the data! And then

Machine Learning and Testing
