An On-device Deep Neural Network for Face Detection
Apple started using deep learning for face detection in iOSÂ 10. With the release of the Vision framework, developers can now use this techno logy and many other computer vision algorithms in their apps. We faced significant challenges in developing the framework so that we could preserve user privacy and run efficiently on-device. This article discusses these challenges and describes the face detec

Attention in Neural Networks and How to Use It
Attention mechanisms in neural networks, otherwise known as neural attention or just attention, have recently attracted a lot of attention (pun intended). In this post, I will try to find a common denominator for different mechanisms and use-cases and I will describe (and implement!) two mechanisms of soft visual attention. What is Attention? Informally, a neural attention mechanism equips a neura

Exploring the structure of a real-time, arbitrary neural artistic stylization network
In this paper, we present a method which combines the flexibility of the neural algorithm of artistic style with the speed of fast style transfer networks to allow real-time stylization using any content/style image pair. We build upon recent work leveraging conditional instance normalization for multi-style transfer networks by learning to predict the conditional instance normalization parameters
