Automatic Alt-text: Computer-generated Image Descriptions for Blind Users on a Social Network Service

CSCW

This paper covers the design and deployment of an automatic alt-text (AAT), a system that applies computer vision technology to identify faces, objects, and themes from photos to generate photo alt-text for screen reader users on Facebook.

Exploring Normalization in Deep Residual Networks with Concatenated Rectified Linear Units

AAAI-17

This paper analyzes the role of Batch Normalization (BatchNorm) layers on ResNets in the hope of improving the current architecture and better incorporating other normalization techniques, such as Normalization Propagation (NormProp), into ResNets.

Optimal User Loading in Massive MIMO Systems With Regularized Zero Forcing Precoding

IEEE Wireless Communications Letters

We consider a downlink massive multiple-input multiple output system employing regularized zero-forcing precoding. We derive the asymptotic signal-to-leakage-plus-noise ratio (SLNR) as both the number of antennas and the number of users go to infinity at a fixed ratio.
