Image Classification with DNNs
Training
cars buses trucks motorcycles
Typical training run
Pick a DNN design
Input 100 million training images
spanning 1,000 categories
One week of computation
Test accuracy
If bad: modify DNN, fix training
set or update training parameters
Why are GPUs good for deep learning?
GPUs deliver --
same or better prediction accuracy
faster results
smaller footprint
lower power

Using DIGITS
Deep Learning GPU Training System
How to start DIGITS
Two options
“digits-devserver”
Starts a development server that listens on port 5000
“digits-server”
Gunicorn application that listens on port 8080. You can configure this with nginx,
and access DIGITS @ http://localhost/
