Distributed Structured Prediction with and without Latent Variables for General Graphical Models
This project subsumes work for learning parameters of structured distributions. Subsequently we detail
  • 1. a method for efficient structured prediction with latent variables for general graphical models
  • 2. distributed learning of structured predictors
  • 3. distribtued cutting plane learning of structured predictors
Thanks for reporting suggestions, bugs and successful use-cases.
 
1. Efficient Structured Prediction with Latent Variables for General Graphical Models
by: A.G. Schwing, T. Hazan, M. Pollefeys and R. Urtasun
In this paper we propose a unified framework for structured prediction with latent variables which includes hidden conditional random fields and latent structured support vector machines as special cases. We describe a local entropy approximation for this general formulation using duality, and derive an efficient message passing algorithm that is guaranteed to converge. We demonstrate its effectiveness in the tasks of image segmentation as well as 3D indoor scene understanding from single images, showing that our approach is superior to latent structured support vector machines and hidden conditional random fields.
