  This paper describes the details of Sighthound's fully automated age, gender
and emotion recognition system. The backbone of our system consists of several
deep convolutional neural networks that are not only computationally
inexpensive, but also provide state-of-the-art results on several competitive
benchmarks. To power our novel deep networks, we collected large labeled
datasets through a semi-supervised pipeline to reduce the annotation
effort/time. We tested our system on several public benchmarks and report
outstanding results. Our age, gender and emotion recognition models are
available to developers through the Sighthound Cloud API at
