Here are some of the technologies we use: Caffe - deep learning feature computation and model training OpenCV - local + other features Zookeeper - service discovery Cascading - batch processing jobs We’ve built infrastructure around some of these libraries to operate at scale. For example we’ve build an incremental feature extraction pipeline that at the core uses caffe + opencv for the feature extraction (more details on how this works is in the paper). We serve our infrastructure through ec2.
