NEURAL NETWORKS NEED DATA

Deep Learning is amazing!

Require huge amounts of quality data

Data needs labeling

For some problems, data + labeling is available

Good data doesn’t exists for most problems

And Labels!

Image-Net (http://www.image-net.org/) example

SYNTHETIC DATA

Real data is expensive, sometimes dangerous

Synthetic labels are automatic and accurate

Useful for validation, in addition to training
